EO Evolutionary Computation Framework

EO has been completely redesigned for version 0.9 and moved to SourceForge. Main EO designers are now Maarten Keijzer and Marc Schoenauer.

You can still download old versions from here, and use http://geneura.ugr.es/~jmerelo/eo for the documentation, ftp://geneura.ugr.es/pub/eo/eo-0.8.7.tgz or ftp://geneura.ugr.es/pub/eo/eo-0.8.7.zip for the release. Latest release is 0.8.7, latest snapshot September 14 1999.

 
• Chromosomes: Can be defined by the user, by subclassing the EOBase class; binary, floating point, bidimensional, string and value plus sigma, used in evolution strategies, are provided. All algorithms defined work on all kind of chromosomes. 
• Genetic operators: Can be defined by the user, by subclassing the EOOp class. Operators can be unary, binary or n-ary (orgy) operators. Many floating point, bitstring, and generic operators are defined, like mutation, crossover, and things like that. 
• Selection/elimination procedure: Can be defined by the user, by subclassing the EOSelect class. Steady-State and rank-based are provided. 
• Reproduction procedure: Can be user defined (I'll skip that from now on, but everything can be user-defined) by subclassing EOBreed. Random, lottery, and rank-based are provided. 
• Replacement procedure: Can be defined by the user, by subclassing the EOReplace class. Eliminate-all, eliminate-worst are provided
• Termination conditions: (user-definable) fitness and generation-based. 
• Algorithms: Easy Ga, Goldberg's SimpleGA, Evolution Strageties and simulated annealing with user-definable cooling schedule. 
• Some utilities: command-line parsing, random-number generations 
• Examples: examples that test all features and classes, plus genetic mastermind. 
• User interface: an example that uses gtk and another with Borland Builderis provided 
• Documentation in html. 

• Linux with egcs 1.0.2 
• Irix 4.0 with egcs 1.0.2 
• Solaris with egcs 1.0.2 and gcc 2.8.1 
• Win95/NT with CygWin/egcs 1.0.2, VC++ 5.0 and Borland Builder. Makefiles and projects files are provided. 

We have also set up remote CVS read access to the source tree. To get the version we are working in currently, first download a cvs client from Cyclic or from your closest GNU repository, and then do this:
bash%export CVSROOT=:pserver:anon@geneura.ugr.es:/home/cvs
or
csh%setenv CVSROOT :pserver:anon@geneura.ugr.es:/home/cvs
and then
$ cvs login
(Logging in to anon@geneura.ugr.es)
CVS password: <press enter here>, and
$ cvs -z9 checkout oldEO
, which will download all the code, compressed to the maximum. This will create the eo source tree; from them on, you can check changes, get daily updates, and so on. This will be much faster than downloading the whole zipfile, and besides, if you have made local changes, cvs will merge them with whatever changes we have made.
