CPU : Intel E8400
OS : Windows XP 64-bit
Time Control : 40 moves in 3 minutes, repeating (Conforms to CCRL 40/4 reference)
Openings : a pgn of ~18,000 games, truncated to 4 full moves. Positions are not repeated
CPUs : 1
Hash : 128 MB
The opponents (at the moment) are:
Houdini 2.0c, Rybka 4.1, Stockfish 2.2.2, Critter 1.4, Naum 4.2, Gull 1.0a,
Spike 1.4, Spark 1.0, and Hannibal 1.2.
All opponents are 64-bit engines except Spike.
The following ratings are approximately how they would appear on the CCRL 40/4 Single CPU Pure List. I am showing only the top 16 engines, but the ratings were computed using the entire database for that list. I am going to give the ratings based on how the CCRL calculates ratings now, how the CCRL may calculate the ratings in the future, and with a beta version of Ordo that can calculate and use White advantage.
