\typeout{Conference Style for ALIFE IX}
% Place this in a file called alife9.sty in the TeX search path.  (Placing
% it in the same directory as the paper should also work.)
% Contact C. Titus Brown, brown@krl.caltech.edu, with any questions.

% 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.

% 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 

%------------------------------------------------------------------
% Please, use pdflatex to create a pdf document. To use pdflatex you will 
% have to convert your figures to pdf files. For this the eps2pdf tool is 
% available. Graphics can then be included with the standard \includegraphics
% command. Size and orientation can be changed with the options [scale],[width]
% and [angle]. 
% In the bibstyle, capitalization is enabled in the 'title' fields. 
%
%------------------------------------------------------------------


% Papers are to be prepared as follows:

%       \documentstyle{article}
%       \usepackage{alife9}
%       \title{Title}
%       \author {Author 1$^{1}$ , Author 2$^{2}$ ... \and Author n$^{n}$\\ 
%       \mbox{} \\ 
%       $^1$ Address line \\
%       $^2$ Address line \\
%       ...
%       $^n$ Address line \\
%       corresponding@author.email}
%
%       \begin{document}
%       \maketitle
%       ...
%       \bibliography{Bibliography-File}
%       \bibliographystyle{alife9}
%       \end{document}


% For several authors from the same institution use the same number to 
% refer to one address. 
% 
% If the names do not fit well on one line use
%         Author 1, Author 2 ... \\ {\Large\bf Author n} ...\\ ...
%
% If the title and author information do not fit in the area allocated,
% place \setlength\titlebox{<new height>} after the \documentstyle line
% where <new height> is 2.25in

% NOTE:  Some laser printers have a serious problem printing TeX output.
% The use of ps type I fonts should avoid this problem.
