Another example I found is the impressive Valkyria program. Version 2.7 won 92% of it's games, more than even the top rated greenpeep0.5.1.
However, the average rating of Valkyria's opponents was only 1722. This is quite a difference. So Valkyria is rated only 2222 compared to greenpeep 2621 despite the fact that it wins more! Of course 2222 is still impressive and Valkyria is number 17 out of all the programs that have played over 200 games (over 200 of them.) - Don Don Dailey wrote: > Let me refer you to the bayeselo web site, this is not my work but due > to Rémi Coulom <http://remi.coulom.free.fr/>.
