About two weeks ago I took Pebbles offline for an extensive overhaul of its board representation. At that time Valkyria 3.3.4 had a 9x9 CGOS rating of roughly 2475.
When I looked today, I saw Valkyria 3.3.4 rated at roughly 2334, so I wondered what was going on. I found a contributing factor: Valkyria has massively different results against Pachi than against Pebbles. It happens that Pachi started playing a day or two after Pebbles went offline. Pebbles and Pachi are both rated around 2200, but Valkyria shreds Pebbles a lot more often than Pachi: Pachi: 185 / 273 = 67.8% Pebbles: 429 / 503 = 85.3% There are a lot of lessons here... _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
