Re: computer-go: using move order information.
In fact the original Wally program does keep track of the last move the
opponent made, and will weigh heavier any response in that area.
This is really not a very good metric, especially in the beginning of
the game, when the object is to enclose as much potential territory as
possible. You do not want to play close to your opponents stones if you
can avoid it. If you look at a professional game, typically there will
be 4 or 5 moves in the same region, then as the moves in that region
effect less territory, then the play will continue on another part of
the board.
