[computer-go] SGF format specification

2007-10-15 Thread Jason House
Is the text at http://www.red-bean.com/sgf/sgf4.html#ebnf-def correct? It seems to me that GameTree = "(" Sequence { GameTree } ")" Is rather restrictive and should possibly be GameTree = "(" Sequence { GameTree } [Sequence] ")" Without a change like that, doing a local variation requires

We faced this when saving each of the SlugGo lookahead paths, one from each CPU. Getting the parens to all match up is critical. Cheers, David On 15, Oct 2007, at 7:13 AM, Jason House wrote: Is the text at http://www.red-bean.com/sgf/sgf4.html#ebnf-def correct? It seems to me that Game

Greetings all, I have been looking through the literature (many thanks to Markus's wonderful online bibliography) on existing strategies in the opening game, and have not found too many articles on the specifics outside of a few papers on neural net learning applied to the opening. There

Have you checked out what Remi Coulom did? http://remi.coulom.free.fr/Amsterdam2007/ It doesn't claim to be the best in the opening, but does claim to do a decent job in the opening (and a better job in the middle of the game) On 10/15/07, Erik S. Steinmetz <[EMAIL PROTECTED]> wrote: > > Greeting

Thanks! That definitely looks like a topical paper that I managed to overlook. On Oct 15, 2007, at 2:02 PM, Jason House wrote: Have you checked out what Remi Coulom did? http://remi.coulom.free.fr/Amsterdam2007/ It doesn't claim to be the best in the opening, but does claim to do a decent

I've tried looking at that 7 page paper, but it seems to be light on detail. Maybe what's given in the paper is enough to reproduce the results, but I'd need to learn the basics of SVM's to know for sure. PS: wikipedia recommends http://research.microsoft.com/~cburges/papers/SVMTutorial.pdf to le

I'm glad you posted about that. I was thinking of it but couldn't remember the name of it. It looks like there may have been some data loss in the past (discussed in blogs). I see several links that are broken. I found the text at http://www.moyogo.com/files/%7BAF6C0FD3-B2EF-4CBE-85CB-7359B82A4
