I have never really understood the idea in all-in-first. That seems to
fly in the face of the common sense idea that the order of moves is
important. But perhaps I have got it wrong in my mind. I will have to
study more.
Actually early in the game the
Ownership map is a good term!
Go81 (and Go169) also uses the ownership map (since 2002). In Palm
handhelds, I can afford to do just two playouts, so the ownership map is
much more informative than the first moves. I look for large neutral
areas (especially moves that are close to both white

I like your program and I actually tested it against yours during
developement. But I didn't test Go169, what is that?
I changed the name from Go81 to Go169 at the time I switched from
PalmOS4 to PalmOS5. It also includes some 5x5 patterns which help with
boards larger than 9x9=81.
Hi,
I thought I'd report a small change I have made to the plain MC
algorithm. I have been unhappy with the fact that the result of the game
gets pressed into one bit (win/loose), and all other information is
discarded. This leads to silly endgame moves, since the algorithm sees
no difference
Heikki,
This is very similar to what AnchorMan on CGOS does. At the end of
each random simulation I keep the same statistcs on each point of
the board and I use it to improve the move selection algorithm. I
call this special board an ownership map for obvious reasons. I
just divide each value

I wonder whether you could save time by not doing this during the
opening? It seems like ownership maps will be meaningless for opening
moves and gradually become more important the closer you get to the
end. It would be interesting to see how many moves into the game you
have to be before it
