Elite 4CPU (live broadcast)

[Kyodai]

Thanks Graham for this very interesting tourney! Since I have made a 5-6 years pause from computerchess, I now followed this battle with great interest. I have added the CEGT-ratings for the engines 40/20. I couldn't find ratings for three of the engines. Top 4 in this tourney was the 4 I knew beforehand as being in the top, having now and then checked ratinglists and such. Ivanhoe took 5th place and this with an engine that is not the strongest one /according to different foras/ - that's very interesting and one could only speculate what Ivanhoe B46 e could have achieved in this tourney.... Also Chiron 1.1 a made a good performance - better than the rating suggests. If anyone could suggest ratings for Ivanhoe, Vitruvius and Strelka, it would interesting. Notably also that Strelka and Komodo only could use 1 cpu (right now)

Sune, try the CCRL 40/40 rating lists. These games contribute to those lists.

IvanHoe 9.46h 64-bit 4cpu is 3220 Elo (CCRL scale).

Strelka 5.1 64-bit is probably around the same strength as Critter 1.4 64-bit 1cpu.

Vitruvius 1.11 64-bit 4cpu is probably a little weaker than Stockfish 2.2.2 64-bit 4cpu.

"IvanHoe 9.46h 64-bit 4cpu is 3220 Elo (CCRL scale)."

Okey, that will put this Ivanhoe level with Stockfish 2.1.1. 64 4 cpu - according to CCRL

That would transform this Ivanhoe to CEGT-rating 3026. Also people suggest that Ivanhoe B46 e might be about 30 points stronger than the version participating in Graham's tourney. Thus we are speaking about rating 3056, which makes this engine very interesting...
