%File: AAAI.Sty-BugList
The following suggestions have been sent to us regarding the AAAI LaTeX 
style file. These modifications may or may not apply to you.
=========================================================================
Latex 2e treats the aaai.sty differently than Latex 2.09, in
particular, adding about a page to a 7 page paper by increasing the
interline spacing.
This is apparently because 2e redefines the "normalsize" macro, while
2.09 defines if from @normalsize. This also scews up the treatment of
\{above,below}display[short]skip.
The workaround is to add the line:
\def\normalsize{\@setsize\normalsize{11pt}\xpt\@xpt}% 10 point on 11
right after the line:
\def\@normalsize{\@setsize\normalsize{11pt}\xpt\@xpt}% 10 point on 11
in aaai.sty.
=========================================================================
Here is a bug fix to the aaai.sty file for Latex from AAAI's web site needed
for my version of latex ("This is TeX, Version 3.1415 (C version 6.1)"):
Change line
\linewidth\hsize \vskip 0.625in minus 0.125in \centering
to
\linewidth\hsize \vskip 0.375in minus 0.125in \centering
to make the title start at the correct height on the page. Otherwise it starts
0.25 in too low. I don't know if this applies to older versions of latex or
not.
=========================================================================
Since I was annoyed by a strange behavior of aaai.sty,
I examined it and found a bug of the style file.
\def\subsubsection{\@startsection{subparagraph}{3}{\z@}{-6pt plus
2pt minus 1pt}{-1em}{\normalsize\bf}}
==> -2pt minus -1pt}{-1em}{\normalsize\bf}}
=========================================================================
In order to use aaai.sty in LaTeX2e it is necessary to comment out the 
\footheight command. You can do so by changing
\setlength\footheight{0pt}  \setlength\footskip{0pt}
to
%\setlength\footheight{0pt}
\setlength\footskip{0pt}
=========================================================================
The \setlength\titlebox{2.25in} is 2.25, while the paper template
looks like it will allow a minimum of 2 in.
Perhaps 2 in. should be the default in aaai.sty?
=========================================================================
The mechanism for invoking styles is different in LaTeX2e.  The mechanism to
use is
\documentclass{article}
\usepackage{aaai}
\usepackage{times}
This assumes that the user has a version of the style file that works with
LaTeX2e.  
Some users may be able to use
\documentstyle[aaai]{article}
to invoke compatability mode, but that may have some problems.

The copyright slug comes too close to any footnotes in the first
column of text; it should have a small vertical separation, especially
as it is not indented, whereas the text of any \thanks{ } footnotes
is indented.  Right now, if the last \thanks{} footnote above
the copyright happens to fill in its last line, it looks like the
copyright slug is part of that same footnote.
The fix is very simple:  on line 133, replace the current line, which
reads
\if T\copyright@on\insert\footins{\noindent\footnotesize\copyright@text}\fi
by
\if T\copyright@on\insert\footins{\smallskip\relax\noindent\footnotesize\copyright@text}\fi
The small vertical skip hardly takes any room on the page, yet makes
the copyright notice stand clearly separate from any preceding
footnote.

Small bug in the definition of \AND, which results in the second
(and any following) "rows" of authors to have their affiliation in
\Large type as opposed to normal size.
Here is the fix: change (starting line 124 of file)

   \def\AND{\end{tabular}\hss\egroup \hfil\hfil\egroup
           \vskip 0.25in plus 1fil minus 0.125in
            \hbox to \linewidth\bgroup\Large\hfil\hfil
              \hbox to 0pt\bgroup\hss \begin{tabular}[t]{c}\Large\bf}

into

   \def\AND{\end{tabular}\hss\egroup \hfil\hfil\egroup
           \vskip 0.25in plus 1fil minus 0.125in
            \hbox to \linewidth\bgroup\hfil\hfil
              \hbox to 0pt\bgroup\hss \begin{tabular}[t]{c}\Large\bf}

that is, simply remove the \Large on line 126.

Hyperref likes to be loaded as the last package since it redefines a lot
of basic LaTeX macros. This includes the definition of the bibitems in
the bibliography, since it adds the anchors for hyperlinks.

Unfortunately, aaai.sty also wants to change the behavior of bibitem,
specifically in order not to print the item key in the bibliography.
When loading aaai.sty before hyperref.sty, these changes get reversed.
As a hack, one can load a style file as the last package which combines
the necessary changes from aaai.sty and hyperref.sty. I have included
such a hack below, but I think one should look into whether this cannot better
be achieved by changing the aaai BibTeX style in order to work together
nicely with hyperref.

I have been using aaai.sty to prepare a paper in latex, and
had thought that the recommended heading

    \documentclass[letterpaper]{article}

would produce the right paper size with both latex and pdflatex.

However, it turns out not to work for pdflatex. The font size gets
shrunk to make the columns fit in A4 width.

After some exploration and consultation with local latex experts,
I have come across two solutions that I have tried which produce
identical effects, which I think are correct, and one solution
that I have not tried, but may also work.

SOLUTION 1 (provided by Mark Roberts):

The "geometry" package provides a very intuitive interface to
those awkward settings. Documentation is here
ftp://tug.ctan.org/pub/tex-archive/macros/latex/contrib/geometry/manual.pdf

The following sets AAAI format:

\usepackage[pdftex,letterpaper,lmargin=0.75in,rmargin=0.75in,tmargin=0.75in,bmargin=1.25in]{geometry}


SOLUTION 2 (found via google):

% Insert conditional instructions for pdflatex
    \newif\ifpdf
    \ifx\pdfoutput\undefined
    \pdffalse % we are not running PDFLaTeX
    \else
    \pdfoutput=1 % we are running PDFLaTeX
    \pdftrue
    \fi

% Set size for pdflatex
% If using only pdflatex, never latex, the two setlength
% commands will work on their own
    \ifpdf
        \setlength{\pdfpagewidth}{8.5in}
        \setlength{\pdfpageheight}{11.0in}
    \fi

SOLUTION 3, which I have not tried:

    \usepackage[pdftex,letterpaper,,...]{hyperref}


No doubt there are lots more solutions. Putting those three in the bugs
file and a warning about pdflatex in the formatting guide should
probably meet everyone's needs.
