This has been explained already. After the first eye appears on the board, the first empty point after the eye has a probability of being picked that is twice the probability of any other empty point. > What good does moving it to the end of the list do?

You move it to the end and you reduce the number of candidates by one. The code is roughly this: int pick(Move *empties, int num_empties) { int num_candidates = num_empties; int picked; do { picked = rand()%num_candidates; num_candidates--; } while(!acceptable(empties[picked]); return picked; } Álvaro. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
