Hello, I have tried to set up the genome size in the program code. (I am loading the parameters from the file, however I want to set up some parameters in the program code.) I plan also to "move" all the parameters from .params file to the program code. Currently I can not somehow access the .setGenomeLength, for particular individual althoug I can access some of the other functions like .genotypeToStringForHumans(): ------- public void evaluate(final EvolutionState state, final Individual[] ind, // the individuals final boolean[] updateFitness, // should this individuals' fitness be updated? // to final boolean countVictoriesOnly, // can be neglected in cooperative coevolution int[] subpops, final int threadnum) { // evaluate together ind[0].setGenomeLength(10); ->> problem is here ! ------------- I suspect that it has to do something with cloning,etc. but I am not sure. Perhaps even better solution is to set up all the parameters within the program code, instead of reading them from the file. I want to set up also the genome length among the other parameters. But how ? Any suggestion/example how to do this initialization in run() ? Nikola
