I also did a study at one time where I tried these doublings against a stable gnugo version and got very similar results - the program went from being crushed by gnugo (rarely winning a game) to the point where gnugo could not win a single game. The ratings differences were very similar at the 3 or 4 levels near gnugo, but at the extreme ranges they were inflated (you can't accurately rate a program that always wins.) To get the most accurate ratings you want to play a good percentage of opponents that are near your own strength. - Don > > Chrisotph > > _______________________________________________ > computer-go mailing list > computer-go@computer-go.org > http://www.computer-go.org/mailman/listinfo/computer-go/ > _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
