Stop looking for, here you got it! Download it and try it! It includes a dummy example to realize how to use the framework, implementing a feature selection problem.
Genetic algorithms are well defined, but people code them again and again. This framework will allow you to just focus in you problem specific implementation, because the well defined parts of the Genetic Algorithms are already implemented and ready to use. Yes, ready to use.
No more copy and paste + refactor, just code your problem specific details and run inside the framework.
From now on, Genetic Algorithms are already done!!
