Ok, that doesn't seem right. Testing with a program that should be close to yours (uniform random playouts except for simple ko and filling its own 'eyes', UCT + RAVE, no exploration term, expanding each node on the second visit), taking black with 6.5 komi against gnugo 3.8 level 6, I get a very neat 30% with 10k playouts, 40% with 50k, 50% with 100k. (Unlike what others are reporting, I do see a big improvement from RAVE even with uniform random playouts.) > but it's not so much the winrate as the fact that the lost games are > almost all W+87.5. I'm not sure that's anything to worry about. Monte Carlo programs don't care whether they lose by a little or a lot, and on a 9x9 board it's easy for everything to die. My program resigns, so I can't give a direct comparison, but it does look like lots of its losses would end up like this. -M- _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
