Excellent, thanks - will ask further questions over there, if needed!

Hi Jan for full controll over the fitness evaluation, you have to implement the Evaluator interface. But be aware that eval method is called twice per generation. The first time at the beginning and the second time after the altering step. If you re-evalute the population only if at least one of the individual needs to be evaluated, the population only needs to be evalutated once per generation. Regards Franz PS: The sourceforge repo has been closed and is only there for historical reasons. For furhter...

Hello Franz, jenetics is great library! I am complete novice on the topic and am currently exploring your library. The documentation is very helpful and good, but I could not figure out a reasonable solution to the following issue: My fitness values are the result of playing a computer game, and it has a random component to how well individuals of the population do (depending on scenario one time it might be "good", another time "bad" - i.e. the function is NOT idempotent). I noticed that the fitness...

Does Jenetics even support fitness function with multiple parameters?? Trying to find the maxima with the following fitness function public static double func(double a, double b, double c) { // f(a, b, c) = 3 * cos(a)^4 + 4 * cos(b)^3 + c return 3 * Math.pow(Math.cos(a), 4) + 4 * Math.pow(Math.cos(b), 3) + c; } Is the following Codec.of correct??? final Codec<Double, DoubleGene> PARAM = Codecs.ofScalar(DoubleRange.of(1, Math.PI)); final Codec<Double, DoubleGene> CODEC = Codec.of( ISeq.of(PARAM, PARAM,...
