Hi, I need to manage a GA run from my own program code. I found an example in the list archives that goes something like this: SimpleEvolutionState state = (SimpleEvolutionState) (Evolve.make(new String[]{"-file","mytest.params"})); int i; for (i=0; i<200; i++){ state.go(); if (state.debugState == state.DEBUG_END) break; } This seems to work fine. Once it's done, how can I obtain the optimal solution (an IntegerVectorSpecies) and use it in my own code for other purposes? Thanks, Sandeep
