There is a system for experimenting with GA's. It is called GENESIS. Here
you have a copy of a post of its release and of how you can get it.

Subject: release announcement: GENESIS 1.1ucsd

I am pleased to announce the release of GENESIS 1.1ucsd, a heavily modified
and enhanced version of the original genetic algorithm simulator by John J.
Grefenstette.  New features (since 1.0ucsd) include:

- support of subdirectory structure for I/O files
- application-specific parameters to the evaluation function
- sigma scaling (a more robust alternative to window scaling)
- stochastic decoding for searching continuous spaces
- super-uniform population initialization option
- support of Dynamic Parameter Encoding - cf. recent TR announcement

Other major differences to standard GENESIS include the ability to use
suitable C functions directly as evaluation functions, and to distribute
a set of simulations to remote hosts.  GENESIS 1.1ucsd can be obtained
via anonymous ftp from the Artificial Life archive server as follows:

% mkdir GAucsd
% cd GAucsd
% ftp iuvax.cs.indiana.edu	(129.79.254.192)
Login: anonymous
Password: <anything>
ftp> cd pub/alife/software/unix/GAucsd
ftp> binary
ftp> get GENESIS.1.Z
ftp> get GENESIS.2.Z
ftp> get GENESIS.3.Z
ftp> get GENESIS.4.Z
ftp> quit
% uncompress GENESIS.?.Z
% chmod +x GENESIS.?
% GENESIS.1
% GENESIS.2
% GENESIS.3
% GENESIS.4
% lpr UsersGuide
% view README

A tech report describing the main new feature, Dynamic Parameter Encoding,
is available in pub/alife/papers/schrau90-dpe.ps.Z on the same ftp server.

If you don't have ftp access, I can honor requests for an e-mail copy
of the source code.  I maintain a mailing list for bug reports, updates,
and other issues pertaining to this simulator - send me a message if
you wish to be added to this list.  Please feel free to send me your
comments, suggestions and experiences regards 1.1ucsd.

I have compiled and tested the code on Sun3, Sun4, Vax, Mips and Pyramid
architectures - if you are installing 1.1ucsd on another system I'd like
to hear whether you had any compatibility problems.

Best regards,
