I was looking over games from this weekend's KGS tournament and found
something I did not expect.
The opponent's first move was F6, a 4-4 point on a 9x9 board.
In looking at the SlugGo global lookahead options, I see the expected
behavior in 2 sequences that are rotations of each other, and the
same influence and territory values are calculated. However two other
options result in exactly the same board, but give different
influence and territory values:
Following from F6, option I is us G4, them C6, us D3, and option L is
us D3, them C6, us G4.
For option I: InfW=-7.00, TerrW=-3.00, InfB=-29.00, TerrB=-3.00
For option L: InfW=-11.00, TerrW=-3.00, InfB=-31.00, TerrB=-3.00
Why would the same board evaluate differently?
Cheers,
David
