Re: [computer-go] Digital Mars
Success! I was able to build on WinXP using Scons and minGW (with gcc4.3.3). Here's what (finally) worked for me: 1. Install Python 2.6.2 http://www.python.org/ftp/python/2.6.2/python-2.6.2.msi 2. Install minGW (using TDM's installer on empty minGW directory) http://downloads.sourceforge.net/tdm-gcc/tdm-mingw-1.902.0-f1.exe 3. Install SCons 1.2.0 http://prdownloads.sourceforge.net/scons/scons-1.2.0.win32.exe 4. add C:\Python26\Scripts\ to path (for scons.bat) 5. add C:\MinGW\bin to path (for g++.exe) 6. unpack latest version of libego http://github.com/lukaszlew/libego/zipball/master 7. edit SConstruct (CXX = g++.exe) 8. run scons.bat (from root directory of libego) 9. run build\example\opt\ego.exe (from root directory of libego) 10. report benchmark results The benchmark results for me were: 31.0417 kpps/GHz Hope this helps.

That seems like a good speed.
On my Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz, using linux and
the exact compiler libego was tuned for, I get 42 kpps/GHz.
On my AMD Athlon(tm) 64 X2 Dual Core Processor 5000+, using the same

Re: [computer-go] Digital Mars
There's a big difference between kpps and kpps/GHz! For your system, you need to divide by two (and on my core2, divide by 1.66). For raw kpps, I think I had 70 on my core2 and 100 on the AMD64. Do you consistently get garbage such as -154.124 for your kpps/GHz?

Re: [computer-go] Roadmap 2020 - using analysis mode to improve programs
I haven't got a ladder example at the moment, but here's an instance where Leela does not realize it is in terrible trouble. I ( with my 8 kyu AGA rating) know with certainty by move 223 (T5) that Black has captured a large white group. A stronger player could read this out sooner than I. This fight is too big to lose for either side; nothing else on the board matters. ( anyone? how early is this outcome pre-ordained? ) Based on the results of its analysis mode, Leela does not recognize the outcome of this semeai until the large white group in the bottom right is down to two liberties. The problem is even more stark in example2 -- similar board, black has foolishly played one of his own liberties for illustrative purposes. It is black's play, black has three liberties, white has three. Black must take away a liberty from white to win the capturing race, or make two eyes at T8. Black has only four playable moves; any other choice fails. Leela proposes - even after several minutes of analysis and a million nodes - that Black should tennuki at H14. That would snatch defeat from the jaws of certain victory; White would dive into T8 and win the race. I started this thread with the contention that analysis mode can help developers find problems, I hope this example explains why. My theory is that if a program could reliably recognize the outcome of such capturing races five or ten moves sooner, it could crush the likes of me. :D Terry McIntyre terrymcint...@yahoo.com Government is an association of men who do violence to the rest of us. - Leo Tolstoy From: Michael Williams michaelwilliam...@gmail.com To: computer-go computer-go@computer-go.org Sent: Tuesday, April 21, 2009 1:57:54 PM Subject: Re: [computer-go] Reply to Lukasz and Don + Roadmap 2020 Mention the program so that the author can either refute your claim or fix the bug. terry mcintyre wrote: Is it reasonable to expect pro players to use 6-dan programs as a tool for analysis?

This fight is too big to lose for either side; nothing else on the board matters. Yes! I use Many Faces and GoGui/Mogo for analyzing games [1]. The ability to be able to weight/suppress moves would be great. E.g. click a couple of white stones and say Stop trying to save these stones, they are dead! Or click all the stones in a group and say: Nothing else matters for either side except the live/death of this group. Or, click a bunch of points and say These are the current hotspots [2] Weighting moves should be relatively easy for programs to implement. The hardest part would be the GUI code. Agreeing on gtp commands for it would be a big first step. BTW, I appreciate that any move filter could lower strength of a program. The two dead white stones both Many Faces and Mogo keep trying to save is a classic example. What they are actually doing is making a dead group slightly stronger, strong enough so that nearby endgame moves switch from being gote to sente. But I'm trying to analyze the difference between two moves in the opposite corner and it is very frustrating when the cursed things keep playing tenuki! Darren [1]: I'm analyzing 9x9 games, and they are generally pro strength from the midgame onwards (bearing in mind their weaknesses of seki, and life/death situations where delicate play is only required by one player). [2]: Where a program could give hotspots 10 times more playouts compared to other moves, at root, with the 10:1 ratio deteriorating to 1:1 after N moves. (E.g. N could be 10, or some function of remaining empty points on board). -- Darren Cook, Software Researcher/Developer http://dcook.org/mlsn/ (English-Japanese-German-Chinese-Arabic open source dictionary/semantic network) http://dcook.org/work/ (About me and my work) http://dcook.org/blogs.html (My blogs and articles) ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] Roadmap 2020 - using analysis mode to improve programs
I've only looked at the first game, but it does seem very interesting to analyze. The white group around H2 is near death as well and I think Leela's evaluation considered that group to be threatened. Once that is solidly alive, it does switch to the semeai on the right. I probably would not have tenuki'd on move 206, but it appears safe when I read out how to respond after move 211. Moves 218 and 220 are reasonable tesuji's when played in a semeai (even if wrong for that semeai). I think you're right that there's probably plenty of analysis to do on how leela went wrong in the game. It may even be that weaker bots read out how to kill the S6 stones on the right and instead of focusing on a liberties race with a one eyed group.
