CEGT 40/20 and 40/120 update (30.September 2007)

Post by Werner »

Hi all, :-)

our new 40/20 and 40/120 rating lists are online, for more details have a look at the links at the end of this posting.

40 / 20:
New in our list are the 4CPU-version of Zappa Mexico x64 and Colossus 2007d. We also made more games with Zappa Mexico x64 2CPU and DeepSjeng 2.7 1CPU. See more in our list "Games of the week".

In total our 40/20 list is based on 184569 games!

New engines:

The 4CPU-engine of Zappa Mexico x64 has cracked the 3000 elo-mark and is now the best MP-engine behind the Rybkas 2.32a x64 with 4 and 2CPUs. The difference to Zap!Chess Zanzibar are only 5 points. There are more games necessary to say more. So the differences between the 4 and 2 CPU versions are not the same: +46 with Zappa Mexico and +64 with Zap!Chess Zanzibar.
Colossus 2007d was the other new engine which could win +44 elos in comparison to our next best version 2007a. Of course all the versions do not have enough games for a sure rating - but we think the new version did a jump in the right direction.

updated engines:

This week we continued testing DeepSjeng 2.7 1CPU. The engine could improve its rating and has now 75 elos more than the version 2.5!! DeepSjeng 2.7 2CPU has now 2797 elos - at the moment only 11 points better than the 1CPU version. The rating is again very close to the 2CPU version.
Rybka 2.32a 4CPU did win some points and is now really close to 3100 elos.

40 / 120:
The new DeepSjeng 2.7 2CPU lost once more some points (-6). It lost the matches against Fritz 10, DeepFritz10, Spike 2CPU, Toga 1.3.1 and DeepShredder 10 2CPU - it only won against ChessTiger last week.

We now make every week an elo-comparison of our lists. As there are a lot of games with the engines we have only small differences. There are 2 exceptions:
DeepJunior 10 2CPU is on 40/120 31 elos better and
Hiarcs 10 is on 40/120 24 elos better.
The other differences are less than 20.

Each week we now make 400-500 games for this list. Our Database consists of 14702 games.

Last week there was also an update of our blitz list.

A big „Thank you“ to all testers as usual!! :)
