  1. JGAP is a Genetic Algorithms and Genetic Programming package written in Java. JGAP version 3.2 represents major feature enhancements, including: + Port to Java version 5 (previously also ran on version 4) + Providing a job-based evolution facility, allowing to run your own computing grid + Improvements in the grid logic (especially concerning the architecture) + Better evolution architecture thanks to the new Breeder class + Caching of fitness computation via introduction of business keys + Speedup + Genetic Programming enhancements + A complex Robocode GP example for evolving pure Java code + A lot of new unit tests (currently we count over 1350 unit tests) + Bug fixes with new unit tests exposing the former bugs + A lot more, see the change log This version includes a lot of input from the growing user base of JGAP.

  2. I've been using this in a prototype project and it has prooved to be very good in a stand alone client, but not so good in a multi-threaded environment (e.g. J2EE) as there are thread safety issues in the Configuration object (a static method needs to be called before a instance can be created using the new operator) as well as far too much use of System properties (imho). Definately worth a look and much kudos to the development team, but make sure you perform adequate due diligence if you intend to use this in a production environment. I wouldn't have normally commented, but since this is ServerSide.com I felt I should have pointed out the issue I was having while trying to integrate this in to a J2EE project. I should also mention that I raised these to Klaus who was very responsive in helping me to identify a solution to my personal problems with regards to the issues mentioned, so thanks Klaus!
