The project has moved on Google Code: http://code.google.com/p/beagle.
Beagle is the best! Thanks.
Open BEAGLE is a very efficient evolutionnary algorithm framework for scientific computing. It is very easy to use on shared memory and distributed memory computer using either, the OpenMP module for the former or the HPC module for the later.
Well designed software that is excellently supported by the main developer. Extensible design allows evolutionary computation in C++ for advanced users, but Beagle comes with sufficient pre-defined code that a beginner can start off immediately from the examples.
