and thanks a lot for the appreciated help.
The problem is that I don't want to limit my parameters, but to introduce some switch within the objective function which leads to a guaranteed removement of the individuum from the population...

Best Regards,

Hi Tobias,

Continuing my email this morning, I don't think GARealAlleleSetArray is likely to solve all the constrain-related problems. You'll probably need something else.

Subject: [galib] Constrainted Optimization


I'm starting my experience with GAlib to solve a constrainted optimization problem. That means, I have absolutely strict boundaries for the optimization. The evolution will generate individuals which are invalid and thus have to be removed from the population before the next generation is created. Now I could just set a very bad cost function for these individuals, but in this case, the population would sometimes contain individuals which are no solution. So I would prefer to "kill"
these individuals - is there already a way within GAlib to do this, or do I have to implement it by myself?

Thanks a lot for your help and 

Best Regards,
