CEGT - rating lists 07.10.2007

[Wolfgang]

Hi all,

our actual rating lists are online and can be found at the attached links

40 / 20

New engines:
Delfi 5.2 is the only newbie this week but had no convincing start. After 645 games it is 17 points behind 5.1.i

Updates:
We played more games with Dual and Quad version of Zappa Mexiko 64bit which did not change facts significantly. Difference to the relative "Zanzibars" are nearly the same (+10 for Quad, +18 for Dual). We also played some new games for Colossus 2007d which decreased difference to next best Colossus (2007a) to 39 points now.
DeepSjeng 2.7 Single also played some more games, also without bigger changes. Difference between Single and Dual still seems a little bit small, we had same effect with version 2.5.

Blitz:
Here i can report "inofficially" that Zappa Mexiko x64 2CPU shows no improvement to Zanzibar after more than 1500 games. Same for Hiarcs 11.2 2CPU and also for the comparison between 32 and 64bit-version of Naum 2.2. Thanks to Christian Koch for these interim infos!

40 / 120:
In the meantime 15.164 games are played with no major news or differences. Each engine played at least 650 games now making ratings reliable now.

A big "thank you" to all testers as usual!

Hi Bigler ,

Zappa Mexico will not be tested in CEGT 40/120, because the difference in the 40/20 list is not big enough compared to the Zanzibar version. But maybe there will be an update for Zappa Mexico gaining a few rating points?

Next tested engine will probably be Deep Shredder 11. Tests will start as soon as it is available.

4 CPU tests in CEGT 40/120 wll start by the beginning of next year, when new versions for Rybka, Hiarcs, Naum, Glaurung, and maybe Spike and others will be out.

Thanks for your interest.
