2019 Formatting Instructions

for Authors Using L

AAAI Press

Association for the Advancement of Artiﬁcial Intelligence

2275 East Bayshore Road, Suite 160

Palo Alto, California 94303

Abstract

AAAI creates proceedings, working notes, and technical re-

ports directly from electronic source furnished by the authors.

To ensure that all papers in the publication have a uniform ap-

pearance, authors must adhere to the following instructions.

Congratulations on having a paper selected for inclusion in

an AAAI Press proceedings or technical report! This doc-

ument details the requirements necessary to get your ac-

cepted paper published using L

X. If you are using Mi-

crosoft Word, instructions are provided in a different doc-

ument. If you want to use some other formatting software,

you must obtain permission from AAAI Press ﬁrst.

The instructions herein are provided as a general guide

for experienced L

X users. If you do not know how to use

X, do not use it to format your paper. AAAI cannot pro-

vide you with support and the accompanying style ﬁles are

not guaranteed to work. If the results you obtain are not in

accordance with the speciﬁcations you received, you must

correct your source ﬁle to achieve the correct result.

These instructions are generic. Consequently, they do not

include speciﬁc dates, page charges, and so forth. Please

consult your speciﬁc written conference instructions for de-

tails regarding your submission. Please review the entire

document for speciﬁc instructions that might apply to your

particular situation. All authors must comply with the fol-

lowing:

•You must use the 2019 AAAI Press L

X style ﬁle and

bib ﬁle, which are located in the 2019 author kit.

•You must complete, sign, and return by the deadline the

AAAI copyright form (proceedings authors) or distribu-

tion license (technical report authors).

•You must read and format your paper source and PDF ac-

cording to the formatting instructions for authors.

•You must submit your electronic ﬁles and abstract using

our electronic submission form on time.

•You must pay any required page or formatting charges to

AAAI Press so that they are received by the deadline.

2019, Association for the Advancement of Artiﬁcial

•You must check your paper before submitting it, ensur-

ing that it compiles without error, and complies with the

guidelines found in the author kit.

All papers submitted for publication by AAAI Press must

be accompanied by a valid signed copyright form or, in the

case of technical reports, by a valid signed permission to

distribute form. There are no exceptions to this requirement.

You must send us the original version of this form. However,

to meet the deadline, you may fax (1-650-321-4457) or scan

and e-mail the form (pubforms19@aaai.org) to AAAI by the

submission deadline, and then mail the original via postal

mail to the AAAI ofﬁce. If you fail to send in a signed

lish your paper. There are no exceptions to this policy.

You will ﬁnd PDF versions of the AAAI copyright and per-

mission to distribute forms in the author kit.

Formatting Requirements in Brief

We need source and PDF ﬁles that can be used in a variety of

ways and can be output on a variety of devices. The design

and appearance of the paper is governed by the aaai style

ﬁle. You must not make any changes to the aaai style ﬁle,

nor use any commands, packages, style ﬁles, or macros

within your own paper that alter that design, including,

but not limited to spacing, ﬂoats, margins, fonts, font

size, and appearance. AAAI imposes requirements on your

source and PDF ﬁles that must be followed. Most of these

requirements are based on our efforts to standardize confer-

ence manuscript properties and layout. All papers submitted

to AAAI for publication will be recompiled for standardiza-

tion purposes. Consequently, every paper submission must

comply with the following requirements:

•Your .tex ﬁle must compile in PDFL

X — no .ps or

.eps ﬁgure ﬁles.

•All fonts must be embedded in the PDF ﬁle — this in-

cludes your ﬁgures.

•Modiﬁcations to the style ﬁle, whether directly or via

commands in your document may not be made, most

especially when made in an effort to avoid extra page

charges or make your paper ﬁt in a speciﬁc number of

pages.

•No type 3 fonts may be used (even in illustrations).

•You may not alter the spacing above and below captions,

ﬁgures, headings, and subheadings.

•You may not alter the font sizes of text elements, foot-

notes, heading elements, captions, or title information (for

references and tables and mathematics, please see the the

limited exceptions provided herein).

•You may not alter the line spacing of text.

•Your title must follow Title Case capitalization rules (not

sentence case).

•Your .tex ﬁle must include completed metadata to pass-

through to the PDF (see PDFINFO below)

•L

X documents must use the Times or Nimbus font

package (do not use Computer Modern for the text of your

paper).

•No L

X 209 documents may be used or submitted.

•Your source must not require use of fonts for non-Roman

alphabets within the text itself. If your paper includes

symbols in other languages (such as, but not limited to,

Arabic, Chinese, Hebrew, Japanese, Thai, Russian and

other Cyrillic languages), you must restrict their use to

bit-mapped ﬁgures.

•Fonts that require non-English language support (CID

and Identity-H) must be converted to outlines or 300 dpi

bitmap or removed from the document (even if they are in

a graphics ﬁle embedded in the document).

•Two-column format in AAAI style is required for all pa-

pers.

•The paper size for ﬁnal submission must be US letter

without exception.

•The source ﬁle must exactly match the PDF.

•The document margins must be as speciﬁed in the format-

ting instructions.

•The number of pages and the ﬁle size must be as speciﬁed

for your event.

•No document may be password protected.

•Neither the PDFs nor the source may contain any embed-

ded links or bookmarks.

•Your source and PDF must not have any page numbers,

footers, or headers.

•Your PDF must be compatible with Acrobat 5 or higher.

•Your L

X source ﬁle (excluding references) must con-

sist of a single ﬁle (use of the “input” command is not

allowed.

•Your graphics must be sized appropriately outside of

X (do not use the “clip” command) .

If you do not follow the above requirements, your sub-

mission will be subject to reformatting and special handling

fees that can easily exceed the extra page fee.

What Files to Submit

You must submit the following items to ensure that your pa-

per is published:

•A fully-compliant PDF ﬁle.

•Your L

X source ﬁle submitted as a single .tex ﬁle (do

not use the “input” command to include sections of your

paper — every section must be in the single source ﬁle).

The only exception is the reference list, which you should

include separately. Your source must compile on our sys-

tem, which includes the standard L

X support ﬁles.

•Only the graphics ﬁles used in compiling paper.

•The L

X-generated ﬁles (e.g. .aux and .bib ﬁle, etc.) for

your compiled source.

•If you have used an old installation of L

X, you should

include algorithm style ﬁles). If in doubt, include it.

Your L

X source will be reviewed and recompiled on

our system (if it does not compile, you may incur late fees).

Do not submit your source in multiple text ﬁles. Your sin-

gle L

X source ﬁle must include all your text, your bibli-

ography (formatted using aaai.bst), and any custom macros.

Accompanying this source ﬁle, you must also supply any

nonstandard (or older) referenced style ﬁles and all your ref-

erenced graphics ﬁles.

Your ﬁles should work without any supporting ﬁles (other

than the program itself) on any computer with a standard

X distribution. Place your PDF and source ﬁles in a

single tar, zipped, gzipped, stuffed, or compressed archive.

Name your source ﬁle with your last (family) name.

Do not send ﬁles that are not actually used in the pa-

per. We don’t want you to send us any ﬁles not needed for

compiling your paper, including, for example, this instruc-

tions ﬁle, unused graphics ﬁles, standard style ﬁles, addi-

tional material sent for the purpose of the paper review, and

so forth.

Obsolete style ﬁles. The commands for some common

packages (such as some used for algorithms), may have

changed. Please be certain that you are not compiling your

paper using old or obsolete style ﬁles.

Using L

X to Format Your Paper

The latest version of the AAAI style ﬁle is available on

AAAI’s website. Download this ﬁle and place it in the T

search path. Placing it in the same directory as the paper

should also work. You must download the latest version of

the complete author kit so that you will have the latest in-

struction set and style ﬁle.

Document Preamble

In the L

X source for your paper, you must place the fol-

lowing lines as shown in the example in this subsection. This

command set-up is for three authors. Add or subtract author

and address lines as necessary, and uncomment the portions

that apply to you. In most instances, this is all you need to

do to format your paper in the Times font. The helvet pack-

age will cause Helvetica to be used for sans serif. These ﬁles

are part of the PSNFSS2e package, which is freely available

from many Internet sites (and is often part of a standard in-

stallation).

Leave the setcounter for section number depth com-

mented out and set at 0 unless you want to add section num-

bers to your paper. If you do add section numbers, you must

uncomment this line and change the number to 1 (for sec-

tion numbers), or 2 (for section and subsection numbers).

The style ﬁle will not work properly with numbering of sub-

subsections, so do not use a number higher than 2.

If (and only if) your author title information will not

ﬁt within the speciﬁed height allowed, put \setlength

\titlebox2.5in in your preamble. Increase the height until the

height error disappears from your log. You may not use the

\setlength command elsewhere in your paper, and it may not

be used to reduce the height of the author-title box.

Inserting Document Metadata with L

PDF ﬁles contain document summary information that en-

ables us to create an Acrobat index (pdx) ﬁle, and also al-

lows search engines to locate and present your paper more

accurately. Document metadata for author and title are RE-

QUIRED. You may not apply any script or macro to imple-

mentation of the title, author, and metadata information in

your paper.

Important: Do not include any L

X code or nonascii

characters (including accented characters) in the metadata.

The data in the metadata must be completely plain ascii. It

may not include slashes, accents, linebreaks, unicode, or any

X commands. Type the title exactly as it appears on the

paper (minus all formatting). Input the author names in the

order in which they appear on the paper (minus all accents),

separating each author by a comma. You may also include

keywords in the Keywords ﬁeld.

\begin{document}\\

\maketitle\\

...\\

\bibliography{Bibliography-File}\\

\bibliographystyle{aaai}\\

\end{document}\\

Illegal Commands

There are a number of packages, commands, scripts, and

macros that are incompatable with aaai19.sty. The common

ones are provided later on in this document (See some Com-

mon Errors to Avoid). Generally, if a command, package,

script, or macro alters ﬂoats, margins, fonts, sizing, lines-

pacing, or the presentation of the references and citations, it

is unacceptable. The following commands are some of the

more common ones that may not be used in your paper (this

list is not exhaustive — there are others):

• \renewcommand (in almost all instances)

• \baselinestretch

• \setlength (except for titlebox)

• \input

• \vspace or vskip (when used before or after a section or

subsection or ﬁgure or table)

• \addtolength

• \columnsep

• \top margin (or text height or addsidemargin or even side

margin)

•trim or clip (used to crop ﬁgures)

•any command that globally alters ﬂoats, space above and

below ﬁgures and tables

Removing Certain Commands in Your Final Paper

For your ﬁnal camera ready copy, you must not use any page

break commands, including, but not limited to:

• \newpage

• \break

• \clearpage

• \pagebreak

(References must ﬂow directly after the text without breaks.)

Note that this may not the case when submitting a paper

for review. Some conferences require references to be on a

separate page during the review process. AAAI Press, how-

ever, does not require this condition for the ﬁnal paper. You

must also be certain that your \pdﬁno author ﬁeld includes

all your authors. The latter step is often forgotten.

Paper Size, Margins, and Column Width

Papers must be formatted to print in two-column format on

8.5 x 11 inch US letter-sized paper. The margins must be

exactly as follows:

•Top margin: .75 inches

•Left margin: .75 inches

•Right margin: .75 inches

•Bottom margin: 1.25 inches

The default paper size in most installations of L

X is A4.

However, because we require that your electronic paper be

formatted in US letter size, the preamble we have provided

includes commands that alter the default to US letter size.

Please note that using any other package to alter page size

(such as, but not limited to the Geometry package) will result

in your ﬁnal paper being rejected.

Column Width and Margins. To ensure maximum read-

ability, your paper must include two columns. Each column

should be 3.3 inches wide (slightly more than 3.25 inches),

with a .375 inch (.952 cm) gutter of white space between the

two columns. The aaai19.sty ﬁle will automatically create

these columns for you.

Overlength Papers

If your paper is too long, turn on \frenchspacing, which

will reduce the space after periods. Next, shrink the size of

your graphics. Use \centering instead of \begin{center}in

your ﬁgure environment. For mathematical environments,

you may reduce fontsize but not below 6.5 point. You

may also alter the size of your bibliography by inserting

\fontsize{9.5pt}{10.5pt} \selectfont right before the bibli-

ography (the minimum size is \fontsize{9.0pt}{10.0pt}.

Commands that alter page layout are forbidden. These

include \columnsep, \topmargin, \topskip, \textheight,

\textwidth, \oddsidemargin, and \evensizemargin (this list

is not exhaustive). If you alter page layout, you will be re-

quired to pay the page fee plus a reformatting fee. Other

commands that are questionable and may cause your paper

to be rejected include \parindent, and \parskip. Commands

that alter the space between sections are forbidden. The ti-

tle sec package is not allowed. Regardless of the above, if

your paper is obviously “squeezed” it is not going to to be

accepted. Options for reducing the length of a paper include

reducing the size of your graphics, cutting text, or paying the

extra page charge (if it is offered).

Figures

Your paper must compile in PDFL

X. Consequently, all

your ﬁgures must be .jpg, .png, or .pdf. You may not use

the .gif (the resolution is too low), .ps, or .eps ﬁle format for

your ﬁgures.

When you include your ﬁgures, you must crop them out-

side of L

X. The command \includegraphics*[clip=true,

viewport 0 0 10 10]... might result in a PDF that looks great,

but the image is not really cropped. The full image can

reappear (and obscure whatever it is overlapping) when page

numbers are applied or color space is standardized.

Type Font and Size

Your paper must be formatted in Times Roman or Nimbus.

We will not accept papers formatted using Computer Mod-

ern or Palatino or some other font as the text or heading type-

face. Sans serif, when used, should be Courier. Use Symbol

or Lucida or Computer Modern for mathematics only.

Do not use type 3 fonts for any portion of your paper,

including graphics. Type 3 bitmapped fonts are designed

for ﬁxed resolution printers. Most print at 300 dpi even if

the printer resolution is 1200 dpi or higher. They also often

cause high resolution imagesetter devices and our PDF in-

dexing software to crash. Consequently, AAAI will not ac-

cept electronic ﬁles containing obsolete type 3 fonts. Files

containing those fonts (even in graphics) will be rejected.

Fortunately, there are effective workarounds that will pre-

vent your ﬁle from embedding type 3 bitmapped fonts. The

easiest workaround is to use the required times, helvet, and

courier packages with L

X2e. (Note that papers formatted

in this way will still use Computer Modern for the mathe-

matics. To make the math look good, you’ll either have to

use Symbol or Lucida, or you will need to install type 1

Computer Modern fonts — for more on these fonts, see the

section “Obtaining Type 1 Computer Modern.”)

If you are unsure if your paper contains type 3 fonts, view

the PDF in Acrobat Reader. The Properties/Fonts window

will display the font name, font type, and encoding proper-

ties of all the fonts in the document. If you are unsure if your

graphics contain type 3 fonts (and they are PostScript or en-

capsulated PostScript documents), create PDF versions of

them, and consult the properties window in Acrobat Reader.

The default size for your type should be ten-point with

twelve-point leading (line spacing). Start all pages (except

the ﬁrst) directly under the top margin. (See the next sec-

tion for instructions on formatting the title page.) Indent ten

points when beginning a new paragraph, unless the para-

graph begins directly below a heading or subheading.

Obtaining Type 1 Computer Modern for L

X. If

you use Computer Modern for the mathematics in your

paper (you cannot use it for the text) you may need

to download type 1 Computer fonts. They are available

without charge from the American Mathematical Society:

http://www.ams.org/tex/type1-fonts.html.

Title and Authors

Your title must appear in mixed case (nouns, pronouns, and

verbs are capitalized) near the top of the ﬁrst page, cen-

tered over both columns in sixteen-point bold type (twenty-

four point leading). This style is called “mixed case.” Au-

thor’s names should appear below the title of the paper, cen-

tered in twelve-point type (with ﬁfteen point leading), along

with afﬁliation(s) and complete address(es) (including elec-

tronic mail address if available) in nine-point roman type

(the twelve point leading). (If the title is long, or you have

many authors, you may reduce the speciﬁed point sizes by

up to two points.) You should begin the two-column format

when you come to the abstract.

Formatting Author Information Author information can

be set in a number of different styles, depending on the num-

ber of authors and the number of afﬁliations you need to dis-

play. In formatting your author information, however, you

may not use a table nor may you employ the \authorblk.sty

package. For several authors from the same institution, use

\and:

\author{Author 1 \and ... \and Author n\\

Address line \\ ... \\ Address line}

If the names do not ﬁt well on one line use:

\author{Author 1} ... \\

{\bf \Large Author ... Author}\\

Address line \\ ... \\ Address line

}

For authors from different institutions, use \And:

\author{Author 1\\ Address line \\ ... \\ Address line

\And ... \And Author n\\

Address line\\ ... \\ Address line}

To start a separate “row” of authors, use \AND:

If the title and author information does not ﬁt in the

area allocated, place \setlength\titlebox{height}after the

\documentclass line where {height}is 2.5in or greater.

Formatting Author Information — Alternative Method

If your paper has a large number of authors from different

institutions, you may use the following alternative method

for displaying the author information.

\author{AuthorOne},\textsuperscript{1}

\author{AuthorTwo},\textsuperscript{2}

\author{AuthorThree},\textsuperscript{3}

\author{AuthorFour},\textsuperscript{4}

\author{AuthorFive}, \textsuperscript{5}\\

\textsuperscript{1}AffiliationOne}\\

\textsuperscript{2}AffiliationTwo}\\

\textsuperscript{3}AffiliationThree}\\

\textsuperscript{4}AffiliationFour}\\

\textsuperscript{5}AffiliationFive}\\

X Copyright Notice

The copyright notice automatically appears if you use

aaai.sty. If you are creating a technical report, it is not nec-

essary to include this notice. You may disable the copyright

line using the \nocopyrightcommand. To change the entire

text of the copyright slug, use: \copyrighttext {text}. Either

of these must appear before \maketitle. Please be advised,

however, that if you disable or change the copyright line and

transfer of copyright is required, your paper will not be pub-

lished.

Credits

Any credits to a sponsoring agency should appear in the ac-

knowledgments section, unless the agency requires different

placement. If it is necessary to include this information on

the front page, use \thanks in either the \author or \title

commands. For example:

\title{Very Important Results in AI\thanks{This work is sup-

ported by everybody.}}

Multiple \thanks commands can be given. Each will result in

a separate footnote indication in the author or title with the

corresponding text at the botton of the ﬁrst column of the

document. Note that the \thanks command is fragile. You

will need to use \protect.

Please do not include \pubnote commands in your docu-

ment.

Abstract

Follow the example commands in this document for creation

of your abstract. Further indentation is not required. Do not

include references in your abstract!

Page Numbers

Do not ever print any page numbers on your paper.

Text

The main body of the paper must be formatted in ten-point

with twelve-point leading (line spacing).

Citations

Citations within the text should include the author’s last

name and year, for example (Newell 1980). Append lower-

case letters to the year in cases of ambiguity. Multiple au-

thors should be treated as follows: (Feigenbaum and Engel-

more 1988) or (Ford, Hayes, and Glymour 1992). In the case

of four or more authors, list only the ﬁrst author, followed by

et al. (Ford et al. 1997).

Extracts

Long quotations and extracts should be indented ten points

from the left and right margins.

This is an example of an extract or quotation. Note the

indent on both sides. Quotation marks are not necessary

if you offset the text in a block like this, and properly

identify and cite the quotation in the text.

Footnotes

Avoid footnotes as much as possible; they interrupt the read-

ing of the text. When essential, they should be consecu-

tively numbered throughout with superscript Arabic num-

bers. Footnotes should appear at the bottom of the page, sep-

arated from the text by a blank line space and a thin, half-

point rule.

Headings and Sections

When necessary, headings should be used to separate major

sections of your paper. Remember, you are writing a short

paper, not a lengthy book! An overabundance of headings

will tend to make your paper look more like an outline than

a paper. The aaai.sty package will create headings for you.

Do not alter their size nor their spacing above or below.

Section Numbers The use of section numbers in AAAI

Press papers is optional. To use section numbers in L

uncomment the setcounter line in your document preamble

and change the 0 to a 1 or 2. Section numbers should not be

used in short poster papers.

Section Headings. Sections should be arranged and

headed as follows:

Acknowledgments. The acknowledgments section, if in-

cluded, appears after the main body of text and is headed

“Acknowledgments.” This section includes acknowledg-

ments of help from associates and colleagues, credits to

sponsoring agencies, ﬁnancial support, and permission to

publish. Please acknowledge other contributors, grant sup-

port, and so forth, in this section. Do not put acknowledg-

ments in a footnote on the ﬁrst page. If your grant agency

requires acknowledgment of the grant on page 1, limit the

footnote to the required statement, and put the remaining

acknowledgments at the back. Please try to limit acknowl-

edgments to no more than three sentences.

Appendices. Any appendices follow the acknowledg-

ments, if included, or after the main body of text if no ac-

knowledgments appear.

References The references section should be labeled

“References” and should appear at the very end of the paper

(don’t end the paper with references, and then put a ﬁgure by

itself on the last page). A sample list of references is given

later on in these instructions. Please use a consistent format

for references. Poorly prepared or sloppy references reﬂect

badly on the quality of your paper and your research. Please

prepare complete and accurate citations.

Illustrations and Figures

Figures, drawings, tables, and photographs should be placed

throughout the paper near the place where they are ﬁrst dis-

cussed. Do not group them together at the end of the pa-

per. If placed at the top or bottom of the paper, illustrations

may run across both columns. Figures must not invade the

top, bottom, or side margin areas. Figures must be inserted

using the \usepackage{graphicx}. Number ﬁgures sequen-

tially, for example, ﬁgure 1, and so on.

The illustration number and caption should appear under

the illustration. Labels, and other text with the actual illus-

tration must be at least nine-point type.

If your paper includes illustrations that are not compatible

with PDFT

X (such as .eps or .ps documents), you will need

to convert them. The epstopdf package will usually work

for eps ﬁles. You will need to convert your ps ﬁles to PDF

however.

Low-Resolution Bitmaps. You may not use low-

resolution (such as 72 dpi) screen-dumps and GIF

ﬁles—these ﬁles contain so few pixels that they are always

blurry, and illegible when printed. If they are color, they

will become an indecipherable mess when converted to

black and white. This is always the case with gif ﬁles, which

should never be used. The resolution of screen dumps can be

increased by reducing the print size of the original ﬁle while

retaining the same number of pixels. You can also enlarge

ﬁles by manipulating them in software such as PhotoShop.

Your ﬁgures should be 300 dpi when incorporated into your

document.

X Overﬂow. L

X users please beware: L

X will

sometimes put portions of the ﬁgure or table or an equation

in the margin. If this happens, you need to scale the ﬁgure or

table down, or reformat the equation. Check your log ﬁle!

You must ﬁx any overﬂow into the margin (that means no

overfull boxes in L

X). If you don’t, the overﬂow text will

simply be eliminated. Nothing is permitted to intrude into

the margin or gutter.

Using Color. Use of color is restricted to ﬁgures only. It

may never be used for any portion of the text of your paper.

The archival version of your paper will be printed in black

and white and grayscale. Consequently, because conversion

to grayscale can cause undesirable effects (red changes to

black, yellow can disappear, and so forth), we strongly sug-

gest you avoid placing color ﬁgures in your document. If

you do include color ﬁgures, you must (1) use the CMYK

(not RGB) colorspace and (2) be mindful of readers who

may happen to have a color deﬁciency. Your paper must be

decipherable without using color for distinction.

Drawings. We suggest you use computer drawing soft-

ware (such as Adobe Illustrator or, (if unavoidable), the

drawing tools in Microsoft Word) to create your illustra-

tions. Do not use Microsoft Publisher. These illustrations

will look best if all line widths are uniform (half- to two-

point in size), and you do not create labels over shaded ar-

eas. Shading should be 133 lines per inch if possible. Use

Times Roman or Helvetica for all ﬁgure call-outs. Do not

use hairline width lines — be sure that the stroke width of

all lines is at least .5 pt. Zero point lines will print on a laser

printer, but will completely disappear on the high-resolution

devices used by our printers.

Photographs and Images. Photographs and other images

should be in grayscale (color photographs will not reproduce

well; for example, red tones will reproduce as black, yellow

may turn to white, and so forth) and set to a minimum of 300

dpi. Do not prescreen images.

Resizing Graphics. Resize your graphics before you in-

clude them with LaTeX. You may not use trim or clip op-

tions as part of your \includegraphics command. Resize the

media box of your PDF using a graphics program instead.

Fonts in Your Illustrations You must embed all fonts in

your graphics before including them in your LaTeX docu-

ment.

The AAAI style includes a set of deﬁnitions for use in for-

matting references with BibTeX. These deﬁnitions make the

bibliography style fairly close to the one speciﬁed below.

To use these deﬁnitions, you also need the BibTeX style ﬁle

“aaai.bst,” available in the author kit on the AAAI web site.

Then, at the end of your paper but before \enddocument,

you need to put the following lines:

\bibliographystyle{aaai} \bibliography{bibﬁle1,bibﬁle2,...}

Please note that you are required to use

\bibliographystyle{aaai}for your references. You may

not use named, plain, apalike, acm, ieeetr, siam, chicago, or

any other style. Use of natbib is also not acceptable.

The list of ﬁles in the \bibliography command should be

the names of your BibTeX source ﬁles (that is, the .bib ﬁles

referenced in your paper).

The following commands are available for your use in cit-

ing references:

\cite: Cites the given reference(s) with a full citation. This ap-

pears as “(Author Year)” for one reference, or “(Author Year;

Author Year)” for multiple references.

\shortcite: Cites the given reference(s) with just the year. This

appears as “(Year)” for one reference, or “(Year; Year)” for

multiple references.

\citeauthor: Cites the given reference(s) with just the author

name(s) and no parentheses.

\citeyear: Cites the given reference(s) with just the date(s)

and no parentheses.

Warning: The aaai.sty ﬁle is incompatible with the hy-

perref and natbib packages. If you use either, your references

will be garbled and your paper will not be published.

Formatted bibliographies should look like the following

examples.

Some Common Errors to Avoid

The following list includes a number of the most common

mistakes made by authors when formatting their paper and

the reponses that have been sent to the author regarding

them:

PDFINFO

The following required elements are missing from the pream-

ble to your LaTeX source (or are malformed):

\pdfinfo{

/Title ()

/Author ()

}

The PDF you submitted is A4. All PDFs must be US Letter

sized. Submissions that do not conform to this requirement

cannot be published.

ABOVEDISPLAY

You’ve used \abovedisplay, \belowdisplay, \above caption,

and \belowcaption to alter aaai19.sty. These commands are

illegal and must be stripped from your source.

ABSTRACT INDENTATION

Remove the \begin{quote}and \{endquote}around your ab-

stract. It might buy you some space.

ASPECT RATIO OF FIGURES CHANGED

You may scale the height OR the width of your ﬁgures, but

not both.

AUTHOR LIST MALFORMED (AUTHBLK)

The authblk.sty package cannot be used.

AUTHOR LIST MALFORMED

You did not use the built-in commands in aaai19.sty to format

your authors. You need to follow the formatting instructions

for authors using LaTeX.

AUTHOR LIST TOO WIDE

Your author list goes beyond the accepted page width. Please

break the line and insert {\bf \Large}around the authors on

the second line. The author and title information must be pre-

sented as speciﬁed in the author instructions.

AUTHOR AFFLIATIONS TOO WIDE

Your author’s afﬁliations go beyond the accepted page width.

Please break the line.

BASELINESTRETCH

You’ve used \baselinestretch — a command speciﬁcally pro-

hibited in the author formatting instructions. Please remove

it.

CAPTION STYLE ALTERED (CAPTION.STY)

You’ve altered the font and style of captions. Captions must

be rendered as speciﬁed by aaai.sty. They cannot be altered

by changing the font, fontsize, or position, whether manually

or by using caption.sty. Such revisions must be removed.

CJK

The CJK package cannot be used. Restrict use of non-roman

alphabets to ﬁgures and tables, which must be compiled and

converted to PDF, then imported as a ﬁgure into LaTeX.

CLIP

You may not use the clip to import only a portion of a graphic.

It only places a fragile layer that screens the remained of the

ﬁgure from view, but imports the entire ﬁgure into the PDF.

The layer is fragile, and often fails when ﬂattened. The full

content of all ﬁgures must be imported. In addition and for the

same reason, you may not use vspace to reposition a ﬁgure.

All ﬁgures must be completely cropped and adjusted outside

of LaTeX before being imported.

COLUMN WIDTH

Unfortunately, your paper contains material that exceeds the

column width. Please review your LaTeX log ﬁle and correct

all the overfull boxes.

COMPILE ERRORS

Unfortunately, the source ﬁle you submitted will not compile.

We are getting undeﬁned control sequence errors. There are

either missing packages in your preamble, or missing deﬁ-

nitions, or perhaps you are using an old or modiﬁed style.

For your information, we are using a complete 2017 install of

TeXLive, complete with all updates as of September 1. The

packages listed in your preamble are all installed on all our

systems. If you are using a style ﬁle that is not in that pack-

age, you will need to include it. Whatever the reason, we need

you to correct your LaTeX and resubmit your source ﬁles. (If

your paper contains graphics, be certain that the fonts are em-

bedded.)

EPSF / EPSFIG / PSFIG

The epsf, epsﬁg, and psﬁg packages are obsolete. Use the

graphicx package instead.

EULER

The euler package is obsolte

FIGURES HAVE BEEN CROPPED WITH LATEX

You have used trim and clip commands in your

\includegraphics statement. Please crop your graphics

appropriately using a standard graphics program (not

Preview). The masks created by LaTeX are fragile, and

disappear when PDFs are combined together. This will result

in text in your paper becoming obscured by the fully restored

graphic you have imported.

FIGURES MISSING

Unfortunately, the source ﬁle you submitted are incomplete.

You did not include the graphics ﬁles. As a result, your paper

will not compile. You must upload a new compressed archive

that contains all the ﬁles required to compile your paper on

a different computer and network. (If your paper contains

graphics, be certain that the fonts are embedded.)

FLOATS ALTERED

You’ve altered ﬂoats. The \renewcommand cannot be used.

The ﬂoat package cannot be used. Please remove them.

FOOTNOTE STYLE ALTERED

Footnotes must follow the built-in style.

FONTS (EMBEDDING)

Unfortunately, one or more of the fonts in your paper (most

likely the ﬁgures) were not embedded in your PDF. This can

cause hidden and silent changes to characters once the paper

is published, especially when it is combined with other PDFs

in the proceedings. If you need to know how to verify the

fonts in your ﬁgures, please search for “font embedding pdf.”

You will ﬁnd a number of methods, one or more of which

may be suitable for your operating system and available soft-

ware. We recommend using Acrobat Reader to check doc-

ument properties in your PDF, as it is standards-based soft-

ware. Consequently, you must embed all the fonts in all your

graphics ﬁles. If you do not know how to do this, change them

to png or jpg.

FONTS (LANGUAGE)

We cannot accept ﬁles that require custom installation of non-

roman font sets, including CJK and arabic.

FONTS (TYPE 3)

Unfortunately, one or more of the fonts in your paper (most

likely the ﬁgures) are type 3 PDF. If in your ﬁgures, you must

either change them to type 1 embedded fonts or change them

to png or jpg. If the problem is in your text, you will need to

switch the package you are using that is calling type 3 fonts

to one that uses type 1 fonts. (Blackboard fonts are often the

problem in these cases.)

FULL PAGE USED

You used \usepackage{full page}, which is a package specif-

ically disallowed. You must remove it.

GEOMETRY USED

You used \usepackage{geometry}, which is a package

speciﬁcally disallowed. You must remove it.

GRAPHICS

The graphics package is obsolete. Use the graphicx package

instead.

HYPERREF

The hyperref package may never be used. If you are using it

for URLs, use url.sty instead

INCOMPATIBLE SCRIPT OR MACRO

You’ve used an incompatible script (such as \maltepaper.sty)

to automate completion of the title and author information

on your paper and in the metadata. Such scripts impede cor-

rection of your paper and often are incompatible with Acro-

bat (producing corrupted metadata ﬁelds). Scripts and macros

cannot be used to automate population of metadata, author or

title information, or insertion of ﬁgures or tables.

LAYOUT

The layout package cannot be used. Use url.sty instead.

LINESPREAD

\linespread alters aaai.sty. This command (along with

\baselineshift and others that alter aaai.sty) cannot be used.

You must remove it.

LMODERN

You used \usepackage{lmodern}, which is a package specif-

ically disallowed. You must remove it.

LAYOUT USED

You used \usepackage{layout}, which is a package speciﬁ-

cally disallowed. You must remove it.

MBOX USED FOR FIGURES

You cannot use mboxes to insert ﬁgures. They circumvent the

spacing requirements for aaai.sty. Use subﬁgures instead.

MULTIPLE TEX FILES

You did not submit a single .tex ﬁle as speciﬁed in the in-

structions. We require this to avoid production errors and to

facilitate debugging. The \input command is not allowed in

your source. Please combine all your tex ﬁles into a single

.tex ﬁle (references can remain in .bbl or .bib ﬁle).

NAMEREF

The nameref package cannot be used.

NATBIB

Natbib is incompatible with aaai19.sty and aaai.bst. It must

be removed. See References Malformed below.

PAGE BREAKS

You’ve included pagebreaks in your ﬁnal submission. (They

are not required before your references accepted ﬁnal papers

and must be removed).

PAGE NUMBERS

Your paper contains page numbers. You need to remove them.

PDFLaTeX NOT USED

Your source will not compile in PDFLaTeX. You must con-

vert your eps graphics to PDF.

PDFCOMMENT

You used pdfcomment, which is a disallowed package. You

must remove it.

PSTRICKS

You used pstricks, which is a package speciﬁcally disallowed.

You must remove it. (Use Tikz instead). If you are simply

adding labels, use pinlabel.sty.

REFERENCES ARE INDENTED

You’ve indented your references. Remove the \begin{quote}

and \endquote

REFERENCES MALFORMED

You’ve used natbib, which is incompatible with aaai.bst.

As an alternate to this, try this workaround:

% \usepackage{natbib}

\newcommand{\citet}[1]

{\citeauthor{#1}˜\shortcite{#1}}

\newcommand{\citep}{\cite}

\newcommand{\citealp}[1]

{\citeauthor{#1}˜\citeyear{#1}}

REFERENCES TOO SMALL

Your references are too small. They cannot be any smaller

than 9 pt (\small). Please correct this.

SAVETREES

The savetrees may not be used.

SETLENGTH

You’ve used \setlength to alter textﬂoats. This command is

speciﬁcally disallowed. Please strip it from your source and

recompile.

SETSPACE

The setspace package may not be used.

SPACE ABOVE, BELOW ELEMENTS ALTERED

You’ve adjusted the space above or below tables, ﬁgures, cap-

tions, ﬂoats, and/or section/subsection/subsubsections. These

changes alter aaai.sty and are not allowed. Please remove

them and either edit your text or resize ﬁgures or both.

SOURCE FILES MISSING

Your compressed archive does not contain *ALL* your

source ﬁles (a stand-alone archive containing all the ﬁles

necessary to recompile your paper in LaTeX). Consequently,

your LaTeX ﬁle will not compile. You must create another

compressed archive in which you have included all the ﬁles

necessary to compile your paper on a separate computer. We

cannot publish your paper without these ﬁles.

SPACE ALTERED ABOVE, BELOW FLOATS AND SEC-

TIONS

You’ve adjusted the space above or below tables, ﬁgures,

captions, and/or section/subsection/subsubsections. These

changes alter aaai.sty and have resulted in a paper that is more

difﬁcult to read. Please remove them and either edit your text

or resize ﬁgures or both.

STYLE FILE OF BIBLIOGRAPHY IS INCORRECT

You did not use aaai.bst (you used named.bst instead). This

is not an IJCAI conference. You need to recompile your bib-

liography using the correct style for AAAI-19.

STYLE FILE IS INCORRECT

You did not use aaai19.sty. This style ﬁle is required. No

other style ﬁle (including previous versions of aaai.sty) may

be used.

STYLE FILE NOT IN CTAN

All styles must be available in the CTAN archive. If they are

custom, you need to remove them and put the contents of

the custom style directly in your preamble so that our source

checker will allow compilation of your ﬁle.

TIMES PACKAGE NOT USED

Your paper is not formatted using the Times package, either

because it is missing completely from your preamble, or be-

cause you are using another package that is cancelling use of

times. This package is required.

TITLESEC

The title sec package may not be used.

VSPACE USED

You’ve used negative vspace around section / subsections.

These must be removed.

TIMES PACKAGE MISSING

You neglected to use \usepackage{times}. This font is re-

quired.

TITLE AND AUTHOR INFORMATION MALFORMED

You need to remove the formatting commands from your ti-

tle and author information. The style for this information is

governed by the conference style ﬁle. It cannot be altered.

TITLE BOX TOO SMALL

Your author-title-afﬁliation data exceeds the limit of the ti-

tle box. To ﬁx this, you need to increase the size of the title

box. You can do this by placing \setlength\titlebox{2.5in}

in your preamble. You may need to increase the measurement

until the log ﬁle error goes away. (Please note: This command

cannot be used elsewhere in the paper, and cannot be used to

shrink the size of the title box.)

TITLE IN SENTENCE CASE

Your title is formatted in sentence case. Title Case (Mixed

Case) is required. Please capitalize the initial letters of all

words in your title except for conjunctions and prepositions.

You need to do this in your source, in the \pdﬁnfo in your

source, and on the submission website.

TITLE MALFORMED (TITLESEC)

You’ve used titlesec.sty, which alters the AAAI style. It must

be removed.

TOCBIBIND

The tocbibind package may not be used.

ULEM

The ulem package may not be used.

T1ENC

The T1enc package is obsolete. Us the CM Super Fonts pack-

age instead.

Producing Reliable PDF

Documents with L

Generally speaking, PDF ﬁles are platform independent and

accessible to everyone. When creating a paper for a proceed-

ings or publication in which many PDF documents must be

merged and then printed on high-resolution PostScript RIPs,

several requirements must be met that are not normally of

concern. Thus to ensure that your paper will look like it does

when printed on your own machine, you must take several

precautions:

•Use type 1 fonts (not type 3 fonts)

•Use only standard Times, Nimbus, and CMR font pack-

ages (not fonts like F3 or fonts with tildes in the names or

fonts—other than Computer Modern—that are created for

speciﬁc point sizes, like Times˜19) or fonts with strange

combinations of numbers and letters

•Embed all fonts when producing the PDF

•Do not use the [T1]fontenc package (install the CM super

fonts package instead)

Creating Output Using PDFL

X Is Required

By using the PDFT

X program instead of straight L

X or

X, you will probably avoid the type 3 font problem alto-

gether (unless you use a package that calls for metafont).

PDFL

X enables you to create a PDF document directly

from L

X source. The one requirement of this software is

that all your graphics and images must be available in a for-

mat that PDFL

X understands (normally PDF, jpg, or png).

PDFL

X’s default is to create documents with type 1

fonts. If you ﬁnd that it is not doing so in your case, it is

likely that one or more fonts are missing from your system

or are not in a path that is known to PDFL

dvipdf Script Scripts such as dvipdf which ostensibly by-

pass the Postscript intermediary should not be used since

they generally do not instruct dvips to use the conﬁg.pdf ﬁle.

dvipdfm Do not use this dvi-PDF conversion package.

Ghostscript

X users should not use GhostScript to create their PDFs.

Graphics

If you are still ﬁnding type 3 fonts in your PDF ﬁle, look at

your graphics! L

X users should check all their imported

graphics ﬁles as well for font problems.

Proofreading Your PDF

Please check all the pages of your PDF ﬁle. Is the page size

A4? Are there any type 3, Identity-H, or CID fonts? Are all

the fonts embedded? Are there any areas where equations

or ﬁgures run into the margins? Did you include all your

ﬁgures? Did you follow mixed case capitalization rules for

your title? Did you include a copyright notice? Do any of

the pages scroll slowly (because the graphics draw slowly

on the page)? Are URLs underlined and in color? You will

need to ﬁx these common errors before submitting your ﬁle.

Improperly Formatted Files

In the past, AAAI has corrected improperly formatted ﬁles

submitted by the authors. Unfortunately, this has become an

increasingly burdensome expense that we can no longer ab-

sorb. Consequently, if your ﬁle is improperly formatted, it

will not be included in the publication. If time allows, how-

ever, you will be notiﬁed via e-mail of the problems with

your ﬁle and given the option of correcting the ﬁle yourself.

A resubmission fee (minimum $50.00, and likely higher)

will be required for this service). Optionally, you may ask

that AAAI have the ﬁle corrected for you, for an additional

fee. If you opt to correct the ﬁle yourself, please note that

we cannot provide you with any additional advice beyond

that given in your packet. Files that are not corrected after a

second attempt will not be included in the publication.

X 209 Warning

If you use L

X 209 we will not be able to publish your

paper. Convert your paper to L

X2e.

Naming Your Electronic File

We request that you name your L

X source ﬁle with your

last name (family name) so that it can easily be differenti-

ated from other submissions. If you name your ﬁles with the

name of the event or “aaai” or “paper” or “camera-ready”

or some other generic or indecipherable name, you bear all

risks of loss — it is extremely likely that your ﬁle may be

overwritten.

Submitting Your Electronic Files to AAAI

Submitting your ﬁles to AAAI is a two-step process. It is

explained fully in the author registration and submission in-

structions. Please consult this document for details on how

to submit your paper.

Inquiries

If you have any questions about the preparation or submis-

sion of your paper as instructed in this document, please

contact AAAI Press at the address given below. If you have

technical questions about implementation of the aaai style

ﬁle, please contact an expert at your site. We do not provide

technical support for L

X or any other software package.

To avoid problems, please keep your paper simple, and do

not incorporate complicated macros and style ﬁles.

Additional Resources

X is a difﬁcult program to master. If you’ve used

that software, and this document didn’t help or some

items were not explained clearly, we recommend you read

Michael Shell’s excellent document (testﬂow doc.txt V1.0a

2002/08/13) about obtaining correct PS/PDF output on

X systems. (It was written for another purpose, but it has

general application as well). It is available at www.ctan.org

in the tex-archive.

Acknowledgments

AAAI is especially grateful to Peter Patel Schneider for his

work in implementing the aaai.sty ﬁle, liberally using the

ideas of other style hackers, including Barbara Beeton. We

also acknowledge with thanks the work of George Ferguson

for his guide to using the style and BibTeX ﬁles — which

has been incorporated into this document — and Hans Gues-

gen, who provided several timely modiﬁcations, as well as

the many others who have, from time to time, sent in sug-

gestions on improvements to the AAAI style.

The preparation of the L

X and BibT

X ﬁles that im-

plement these instructions was supported by Schlumberger

Palo Alto Research, AT&T Bell Laboratories, Morgan Kauf-

mann Publishers, The Live Oak Press, LLC, and AAAI

Press. Bibliography style changes were added by Sunil Is-

sar. \pubnote was added by J. Scott Penberthy. George Fer-

guson added support for printing the AAAI copyright slug.

Additional changes to aaai.sty and aaai.bst have been made

by the AAAI staff.

Thank you for reading these instructions carefully. We look

forward to receiving your electronic ﬁles!
