Hi, Thanks for your answer and sorry I wasn't clear enough. I think I followed the different steps you described. I adapted the code from ZeroMin, and here is...
Christian: Can you see what's not right here? Bastien: I cannot see what might be wrong. My recommendation would be to pepper your code (and if necessary,...
Hi everyone, I am quite new to genetic programming and open beagle and am interested in learning more about this great tool and technique. I am wondering if...
Hi Paul, My ten cents would be to try to avoid them! No, honestly. The issue with loops and evolution is that an individual might just randomly ask to loop...

Hello, Your message is not totally clear. What do you want precisely? To extract the best-of-generation individual in your fitnesse evaluation operator? If so,...
Hi Christian, You got it. You got what I need. Let me say that what you proposed worked fine! and better than this, you took time to explain (write) how to do...
