Hi Michael
Another cost is undo. Superko requires undo, unless you want store a hash value with each chain of stones. I am not sure exactly what undo costs, but lets say 5% to 10%.
Well, every implementation is different. In its slowest mode, my board stores information about neighbor stones in each cell. It has a stack of boards and each board has a pointer to its parent. In that mode superko can be detected. There is also a faster mode for MC playouts that does not support superko. But it could also be possible to maintain a stack of previous hashes i.o.
complete boards, that would not be very expensive. Jacques. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
