1) How do I save the best-of-generation individual to a file each generation (or every N generations)? My individuals are too large to print, and I'd like to do some other things with them after I evolve them. 2) As mentioned, I'm coevolving Go players. To see that I'm making progress, I'd like to test the best-of-generation individual against a random player and against a known good player every so many generations. Is there any easy way to do this? FAQ pointers appreciated, Peter Drake Assistant Professor of Computer Science Lewis & Clark College http://www.lclark.edu/~drake/
