My Palm program does the ownership map idea - in fact it IS the same program as AnchorMan when it's set to the highest level which does 5000 simulations. To get 5000 simulations out of a palm, I had to code for the ARM processor, so the program has code inside of it for the old and the new style of processors. I didn't time it, but it will also do 5000 simulation on older palms, you just have to wait, probably 2 or 3 minutes per move I'm guessing, it's an enormous difference - something like 20 to 1 or more. I like your program and I actually tested it against yours during developement. But I didn't test Go169, what is that? I wanted to advertise it as the "strongest palm go program" so I tested against all the go programs I could find for the palm. I assume Go81 would play much stronger if you compiled it for the ARM as I did. - Don _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
