Paradiseo-EO
Paradiseo-EO deals with population based metaheuristics, it is a templates-based, ANSI-C++ compliant evolutionary computation library (evolutionary algorithms, particle swarm optimization...). It contains classes for almost any kind of evolutionary computation you might come up to - at least for the ones we could think of. It is component-based, so that if you don't find the class you need in it, it is very easy to subclass existing abstract or concrete classes.
