GPalta

Welcome to GPalta's homepage

GPalta is a Genetic Programming toolbox written in Java. Its main design goals are:

• Simplicity, both for the user and the developer
• Speed

GPalta is considered in beta stage, with many features incomplete or simply missing. However, it’s currently being used succesfully in our labs. It’s published here in the hope that it will be usefull for somebody else.

Feel free to contact the authors for any comments (bug reports are specially welcome)

• Tree based genetic programming
• Strongly Typed (optional)
• Multi threaded evaluation of individuals and fitness assignment
• Multi threaded graphical interface to control an evolution process
• Evolutions can be saved to file, and be continued later (and/or elsewhere)

• Ease of use:
• For GP aplications, all you have to do is provide fitness cases, configure some usual GP options and click go (or call evolve from Matlab)
• For advanced research, GPalta can be easily extended with custom nodes, fitness, operators, etc

To see what's new in this release, read the changelog

• gpalta-0.4.zip. December 19th, 2007

The .zip file includes all the necessary files to run GPalta. It also includes the full source code and documentation.

You can view the most up to date source code online in the subversion repository (see branches/multitree). Instructions on how to get a local copy of the code can be found on the BerliOS project page.

• For stand alone usage, see the readme.txt file

• For usage from Matlab, we recommend reading the GPalta from Matlab tutorial.

• For more detailed information, you can consult the api specifications

• Please note that online documents might be a little out of date, because of changes made in the source code. This will change once a 1.0 release is made, as the API should remain stable thereafter.
