[computer-go] Exact dates for Chou vs Bots ?

2009-08-20 Thread Ingo Althöfer
Does someone here know the exact starting times (in common time zones) for the 19x19 exhibition games * Chou(9p) vs MFoG (Fr, August 21) * Chou(9p) vs Zen (Sa, August 22) ? Thx in advance. Ingo. PS: I will reply later to the interesting postings by Brian Sheppard and Weston Markham on

The timezone of Korea is the same as Japan (GMT+0900). In addition, Korea has no daylight-saving, I strongly believe but not guranteed, sigh. Hope this helps. Hideki Ingo Althöfer: 20090820084712.136...@gmx.net: Does someone here know the exact starting times (in common time zones) for the

[computer-go] Laziness (was: Dynamic komi)

2009-08-20 Thread Brian Sheppard
I'm curious to find out what is meant by lazy. If, as I am led to believe by your report, Monte Carlo strategies applied to Double Step Races are lazy, yet they converge to perfect play, then I'm not sure why we are meant to worry. We worry because the 7 facts below combine to propagate bad

I'm glad to see some are actually experimenting with this. My suggestion is to modify a program such as fuego to follow one of the algorithms as suggested - then test it with a large sample of games. If it doesn't work we can experiment until it does or until we are satisfied that it won't.

[computer-go] Cycles / super ko in tree search

2009-08-20 Thread Jason House
I changed my search from one tree per search thread to a shared (lock- free) tree among all threads. Back with dedicated trees, I would set a visited flag as I walked the tree. With a shared tree are there any clever ways to detect cycles / super ko? Here are the two ideas I'm thinking of:
