Do you really stop the simulation after a single pass, ie. when
one side has no more move to play but the other does?
I believe that this would end many games before they are (really) over
and that might lead to false results in the simulations.

Actually, that's the only difference between housebot-621-amaf and
hb-amaf-alt. alt is playing games all the way to the end like you
suggest. Looking at the win rate against ego110_allfirst, it looks like
it may be doing a bit worse (but more samples are needed). It's
unfortunate that ranks that low vary so much based on which bots are on
CGOS.
In the future, I'll probably offer the option to do either method. My
logic behind stopping at the first pass is that it's highly unlikely to
form life in the void from captured stones. Since capturing the stones
would increase the length of the game and isn't very likely to change
the outcome of the game, I figured it'd be a good compromise.

Re: [computer-go] Update of MoGo binary release, and windows version available!
I tried to start this version of Drago, and got an error message regarding a missing libkombilo.dll I do have an earlier version of Drago which works, modulo the problems with Mogo.

Hello Dave, bonjour Sylvain, yes they are some problems to use MoGo with Drago. The main issue is the initial message written to stderr as guessed by Dave. Actually, Drago handles incorrectly stdout and stderr in the same way but this is easily corrected. I have uploaded a patch for using MoGo with Drago: www.godrago.net/DragoForMogoPatch.zip. The zip contains an exe file which should replace the one from the current Drago install. As MoGo does not implement the GTP command final_result, an error message is displayed at the end of the game and the user must count the result. (By the way, is there a problem with 'final_status_list alive' ?) I could let the dll and the data files in MoGo folder without any problem.

Re: [computer-go] Update of MoGo binary release, and windows version available!
Sylvain, There is nothing to apologize for. Writing to stderr is fine. Putting the .dll in the same directory is fine. Mogo does work from the command line. No error message. I can recreate the symptoms with my own engine by adding an extraneous?"printf." "fprintf(stderr," does not cause problems. Whether it gives an error message or not beyond the "abort" depends on what I print. It could be that there are some?stray printf's, not directed to stderr, somewhere in Mogo. It seems to happen in response to genmove (perhaps when reporting the time) and also when reading the opening file. I can delay the abort by running with "--useOpeningDatabase 0" but only until the first "genmove." Mogo responds to some other commands like "name", "version", "komi", "boardsize", "clear_board", and "play", without problems. - Dave Hillis -Original Message- From: Sylvain Gelly <[EMAIL PROTECTED]> To: computer-go Sent: Wed, 19 Sep 2007 4:03 am Subject: Re: [computer-go] Update of MoGo binary release, and windows version available!

Re: [computer-go] Re: Most common 3x3 patterns
I neglected the rather important detail that these patterns are trained on 9x9 games. Training on 19x19 games produces different scores than these. I've tried it both ways (it's much easier to get a large set of 19x19 games for training) and this set is the one I now use for both 9x9 and 19x19. But my program's performance on 19x19 is terrible either way. IIRC, if I train on 19x19 games, but only keep track of patterns with a center within the 5x5 window around the enemy's previous move, then I get scores very similar to those from 9x9 games. - Dave Hillis -Original Message- From: [EMAIL PROTECTED] To: computer-go@computer-go.org Sent: Tue, 18 Sep 2007 11:20 pm Subject: Re: [computer-go] Re: Most common 3x3 patterns >-Original Message- >From: Jason House <[EMAIL PROTECTED]> >To: computer-go >Sent: Tue, 18 Sep 2007 7:37 pm >Subject: Re: [computer-go] Re: Most common 3x3 patterns > > >[EMAIL PROTECTED] wrote:? >> I have a set of 3x3 patterns trained on a subset of the ~20K games in > the >> NNGS file that's floating about.
