[computer-go] Changed game-end procedure for KGS bot games

2009-09-30 Thread Nick Wedd
In previous KGS bot tournaments, players including EricaBot and housebot have been losing won games, through no fault of their own, because they do not support the game end protocol. As I wrote in my report of the September tournament: EricaBot obtained a clearly won game against GnuGoAl. But t

Look for the graph I posted a few weeks ago. Most things tried make it worse. Some make it a little better, and every now and then there is a big jump. David > I'm wondering, are these tunings about squeezing single-percent > increases with very narrow confidence bounds, or something that gives

Well I have no idea how much I gained from this. It might be weaker than what everyone else is doing, since it seems I didn't implement this as it's been described recently. My progressive widening only uses Rave values. It's very simple. Others seem to have much more complex schemes. But I don

I'm trying an experiment. I took the Many Faces code completely out of the engine, and put it on 9x9 cgos as mfgo-none-1c. It's faster without Many Faces, but it's just a basic uct engine with medium playouts. This should tell us how much benefit I get from the Many Faces knowledge. David >
