Not necessarily. All I need is a learning algorithm that really knows how to
avoid playing the same lost game twice, and maybe tries from time to time to
replay a won game. That does not imply I'm going to buy 10 computers and let
them play auto232 matches all day.
Anyway I don't have enough money for that.
