\typeout{Conference Style, version of 6 September 1995 (revised Nov 2010)}

% All bug reports should be directed to kek@cs.brown.edu
% The following comments are from the original ijcai97.sty

% The current two-column conference style.
% Originally used for IJCAI-89.
% Fixes from various people incorporated up to the IJCAI-95 style.

% To use, place in a file called conference.sty, or whatever your conference
% is called, in the TeX search path.  (Placing it in the same directory as
% the paper should also work.)

% Prepared by Peter F. Patel-Schneider,
% liberally using the ideas of
% other style hackers, including Barbara Beeton.
% This style is NOT guaranteed to work.  It is provided in the hope
% that it will make the preparation of papers easier.
%
% The preparation of this file was supported by Schlumberger Palo Alto
% Research, AT\&T Bell Laboratories, AAAI, and Morgan Kaufmann Publishers.

% \pubnote added by J. Scott Penberthy

% These instructions can be modified and used in other conferences as long
% as credit to the authors and supporting agencies is retained, this notice
% is not changed, and further modification or reuse is not restricted.
%
% If you are organizing a conference, and want to use this file, you should
% appoint a contact person to handle any problems!
%
% If you are using this file for the preparation of papers for a
% conference that supplied you with this file, you should contact the
% organizers of the conference if you have any problems.  They should have
% much more information than I have.

% There are undoubtably bugs in this style.  If you make bug fixes,
% improvements, etc.  please let me know.  My e-mail address is:
%       pfps@research.bell-labs.com

% Papers are to be prepared using the ``named'' bibliography style,
% included in this file, which implements long and short citations.
%
%       \documentstyle[conference]{article}
%       \title{Title}
%       \author{Author 1 \and Author 2 \\ Address line \\ Address line \And
%               Author 3 \\ Address line \\ Address line}
%       \pubnote{\em To appear, AAAI-94}  % optional, remove for submission
%       \begin{document}
%       \maketitle
%       ...
%       \bibliography{bibliography-file}
%       \bibliographystyle{named}
%       \end{document}
%
% \pubnote is for printing the paper yourself, and should not be used in
% submitted versions!!!!

% Author information can be set in various styles:
% For several authors from the same institution:
% \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 Author 2} \\ ... \\ {\bf Author n} \\
%         Address line \\ ... \\ Address line}
% For authors from different institutions:
% \author{Author 1 \\ Address line \\  ... \\ Address line
%         \And  ... \And
%         Author n \\ Address line \\ ... \\ Address line}
% To start a separate ``row'' of authors use \AND, as in
% \author{Author 1 \\ Address line \\  ... \\ Address line
%         \AND
%         Author 2 \\ Address line \\ ... \\ Address line \And
%         Author 3 \\ Address line \\ ... \\ Address line}

% If the title and author information does not fit in the area allocated,
% place \setlength\titlebox{<new height>} after the \documentstyle line
% where <new height> is something like 2.5in

% NOTE:  Some laser printers have a serious problem printing TeX output.
% These printing devices, commonly known as ``write-white'' laser
% printers, tend to make characters too light.  To get around this
% problem, a darker set of fonts must be created for these devices.

% Physical page layout

\typeout{Named Citation Style, version of 30 November 1994}

% This file implements citations for the ``named'' bibliography style.
%  Place it in a file called named.sty in the TeX search path.  (Placing it
% in the same directory as the LaTeX document should also work.)

% Prepared by Peter F. Patel-Schneider, with the assistance of several,
% since forgotten, LaTeX hackers.
% This style is NOT guaranteed to work.  It is provided in the hope
% that it will make the preparation of papers easier.
%
% There are undoubtably bugs in this style.  If you make bug fixes,
% improvements, etc.  please let me know.  My e-mail address is:
%       pfps@research.att.com

% The preparation of this file was supported by Schlumberger Palo Alto
% Research and AT\&T Bell Laboratories.

% This file can be modified and used in other conferences as long
% as credit to the authors and supporting agencies is retained, this notice
% is not changed, and further modification or reuse is not restricted.

% The ``named'' bibliography style creates citations with labels like
%       \citeauthoryear{author-info}{year}
% these labels are processed by the following commands:
%       \cite{keylist}
%               which produces citations with both author and year,
%               enclosed in square brackets
%       \shortcite{keylist}
%               which produces citations with year only,
%               enclosed in square brackets
%       \citeauthor{key}
%               which produces the author information only
%       \citeyear{key}
%               which produces the year information only
