Gabriel, I don't think that MC players are aware of "local fights". It would be very nice if a program could divide the board in separate locations, because the combinatoric explosion would be reduced by a huge factor (4 areas with 16 empty intersections has a much smaller game tree than 1 area with 64 empty intersections). There is a method of combining the results of local endgame fights in a global result (Winning Ways by Conway, it can be viewed as a way to determine the optical merging of sepatate game trees), but in earlier stages of the game it is hard to separate out areas of the board that have low interaction. Perhaps it could be derived in an MC way (statistically) from cross correlations of board occupance at playout terminal nodes. I gave that a try a couple of years ago, but I gave up when it didn't seem to give useful results. Could be due to bugs in my code though. Dave

For example, when there are several fights happening simultaneously at the board, a human player can identify them and decide which one worth more to invest, I thinks this is a really difficult task in Go. How does he do this judge ? Which features does he analyze? And there are cases which "try" to mimic the biological solution is worth. See Neural Networks, Ant Colony Optimization Algorithm, Genetic Algorithm, etc. Santos, Gabriel.

Do you also think a machine that carries people very fast should have strong legs like a horse? And a machine that can fly should flap its wings like a bird? And a closer example: Do you think the same thing about chess machines? In all those cases the engineering solution to the problem was very different from the biological solution, and I expect the same will happen with computer go. Actually, it's already happening.
