Dear all, I am trying to let the GA make adjustments every x generations. Through statistics I can invoke the number of the current generation, but how can the GA do this while evolving? Being no expert on C++, any help is welcome. Thanks, Sanne. ** Sanne Houweling - (+31)207705488 - sanne at cs.vu.nl ** ** Faculty of Exact Sciences - Vrije Universiteit Amsterdam**
