Re[2]: [computer-go] Library of Effective GO routines v 0.106

ah I see. I ran some tests and here is what I got:

Komi=7.5
P(Black wins)=41.4%

Komi=6.5
P(Black wins)=44.5%

Komi=5.5
P(Black wins)=44.1%

Komi=4.5
P(Black wins)=46.7%

Komi=3.5
P(Black wins)=47.0%

Komi=2.5
P(Black wins)=49.7%

Komi=2.0
P(Black wins)=49.7%

Komi=1.5
P(Black wins)=49.6%

Komi=1.0
P(Black wins)=49.6%

Komi=0.5
P(Black wins)=52.4%

Black wins on average by 2 points (without komi). So for these random games a komi of 2.5 seems reasonable. Can someone also run the same experiments?
