Fix for H9 games #40

Closed lemonsqueeze closed 6 years ago

lemonsqueeze commented 8 years ago

Hi,

I noticed Pachi resigns 9 stones handicap games as white. Looks like passing dynkomi=linear:handicap_value=8%8 fixes it, Shouldn't it be the default ?

If you look at the history of uct/dynkomi.c, you see that jlg progressively reduced handi value in pachi-as-white games as it improved performance for lower-handi games. In 4-handi game, 32 komi vs. 4 komi at the beginning is a huge difference. Maybe a better+simpler fix would be to just prohibit resignation in first ~50 moves.
