Re: [Computer-go] Congratulations to Crazy Stone!
Thanks Nick, as you ask both programmers to handle clean up correctly (round 2): I would say NiceGo did. It is by design, that it passes for the end of game if it counts a win with the clean-up rules. If you think, this is wrong handling, please explain. Of cause we want to do good handling of the clean-up phase. Our opening as black is really strange (round 3). We open much better with fewer playouts:) Therefore the other thread about strength vs. playouts:) Detlef Am Montag, den 18.11.2013, 19:41 + schrieb Nick Wedd: Congratulations to Crazy Stone, winner of yesterday's KGS bot tournament, with 12 wins from 12 games!

From the command line documentation I thought pondering is off by default.and I did not check it:( pachi -d 0 -t =4000 -r chinese threads=1,max_tree_size=2048 Also, it may be worth passing pass_all_alive unless you are doing a sophisticated scoring procedure, to make sure Pachi captures all dead groups at the end of the game. P.S.: Do your results imply that on 4000 playouts/move, oakfoam is quite stronger than Pachi now? I'd love to hear more. :) How does the playout speed compare? Yes, we play even with 1000 against this settings. But I did not take pondering into account, as I thought it is turned off. Therefore I do not know if pachi really played 4000 playouts, as I thought. We have a little less than 1000 playouts/core/second. And my main aim is to get the iPad version strong, therefore the strength with lower playouts is more important to me. I did not optimize parameter against pachi alown, I started running clop with three opponents gnugo level 10, pachi with this setting and /home/detlef/fuego-1.1/fuegomain/fuego with setting uct_param_player ignore_clock 1 uct_param_player max_games 3000 uct_param_player resign_min_games 5000 uct_max_memory 3 All 4 programs have comparable strenght than. Always happy to share any idea:) Detlef ___ Computer-go mailing list Computer-go@dvandva.org http://dvandva.org/cgi-bin/mailman/listinfo/computer-go

Of cause we want to do good handling of the clean-up phase. I don't think it is wrong. I do think it is inadvisable. You are trusting the server's score-counter to count in the way that you expect, when there are dead groups on the board and it can reasonably assume that there are no dead groups on the board. For instance, in the position shown, it counted B2 as a point for White, even while it was regarding the black stones at C1 and C3 as alive. Did your code _know_ it was going to do that? Our opening as black is really strange (round 3). We open much better with fewer playouts:) Therefore the other thread about strength vs. playouts:) It worked well against Orego :-) Nick Detlef Am Montag, den 18.11.2013, 19:41 + schrieb Nick Wedd: Congratulations to Crazy Stone, winner of yesterday's KGS bot tournament, with 12 wins from 12 games!
