You missunderstood my point. However, I admit it was not clear. What i wanted to say is this : Given a fixed amount of time, strength of monte-carlo algorithm will decrease exponentialy when boardsize increases. It does not mean that monte-carlo does not scale well with time on 19*19. Of course, it all depends on the referential you use to measure strength. By the way, it is not a critisism towards UCT : actualy I do think monte-carlo is the key to build realy strong programs. I just wanted to state that scaling with computation-time is not the only thing that matters. Scaling with board size matters too. It was not another criticism towards you opinion either.

This can be tested directly. In my own experiments 19x19 improves very rapidly in UCT with each doubling of the number of play-outs. Of course someone will say, "yes, but that won't continue" and I will have no way to refute their intuition. I am presenting real evidence that it scales at least as far as I can test, and nobody has presented any evidence whatsoever to the contrary other than gut feelings. - Don _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/ ___________________________________________________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
