Hi. I'm trying to make a GA problem in which each evaluation of individuals is other GA. I've followed the example in this list of GA nested GP, but it doesn't work. My code is: --- File f = new File("ec/app/EC/EC.params"); try{ dataB = new ParameterDatabase(f); }catch(Exception e){ System.out.println(e); } state2 = Evolve.initialize(dataB,ECRandomOffset++); --- when it is executed, dataB has got all parameters of EC.params, but state2 doesn't. Where is the mistake? Thank you.
