Hi all, I am trying to force an evaluation because I use an adaptive fitness function (with SStateGA): pop->evaluate(gaTrue); But it seems this is not passed through to the evaluation of the genomes. Who knows how to achieve this? Thanks, Sanne. ** Sanne Houweling - (+31)207705488 - sanne at cs.vu.nl ** ** Faculty of Exact Sciences - Vrije Universiteit Amsterdam**
