CCRL rating lists updated (5th February 2010)

[Graham Banks]

The latest CCRL Rating Lists and Statistics are available for viewing from the following links:
http://computerchess.org.uk/ccrl/4040/ (40/40)
http://www.computerchess.org.uk/ccrl/404.live/ (40/4)
http://www.computerchess.org.uk/ccrl/404FRC/ (FRC 40/4)

Please note that the three lists are updated separately to each other.
The links given in each update report will give you the currently up to date lists.

The links to the various rating lists can be found just beneath the default Best Versions list (as in this screenshot). Specific 32-bit rating lists are denoted as such to the right of the default list in each category. The default lists contain the 64-bit engines.



Our 40 moves in 40 minutes repeating and 40 moves in 4 minutes repeating are both adjusted to the AMD64 X2 4600+ (2.4GHz).

Currently active testers are Graham Banks, Ray Banks, Shaun Brewer, Aser Huerga, Kirill Kryukov, Dom Leste, Denis Mendoza, Cody Rowland, Wassim Saeed, Charles Smith and Gabor Szots.

Be aware that in the early stages of testing, an engine's rating can often fluctuate a lot.
It is strongly advised to look at the many other rating lists available in order to get a more accurate overall picture of an engine's rating relative to others.

The LOS (likelihood of superiority) stats to the right hand side of each rating list tell you the likelihood in percentage terms of each engine being superior to the engine directly below them.

All games are available for download by engine, by month or by ECO code (not from the live links though - remove the .live).
ELO ratings are now saved in all game databases for those engines that have 200 games or more.

Clicking on an engine name will give details as to opponents played plus homepage links where applicable.

Custom lists of engines can be selected for comparison.

An openings report page lists the number of games played by ECO codes with draw percentage and White win percentage. Clicking on a column heading will sort the list by that column.

For any testers interested in joining our group, please read our homepage before applying.

Hi Graham
some days ago I downloaded Spark_0_3_64-bit_MSVC_4CPU.commented.[404].pgn.7z , Now I don´t see this file, what could happened? the same for another shredder 12 settings like Deep_Shredder_12_64-bit_OA_Off_4CPU.commented.[268].pgn.7z, and I download the last update of total Database (40/40) but when I filter to search, for say Rybka 3 64 bit 4CPU I get only 1400 games, and in the engine section the same Rybka have 1470 so it could be nice for all your "customers" that each type of download have the same update, don´t u think so?
Tnx in advance!! and great work Graham!! oh by the way , why CCRL don´t test any Rybka Winfinder version yet??

Hi Armando,

I'll get Kirill to answer your database query.

I'm guessing that Rybka Winfinder hasn't been tested because of many reasons:

- it was designed to be a problem solver rather than a standalone engine.
- there are too many other engines to test that deserve our attention
- nobody is interested in testing it as a playing engine.

Cheers,
Graham.

Hi Graham
some days ago I downloaded Spark_0_3_64-bit_MSVC_4CPU.commented.[404].pgn.7z , Now I don´t see this file, what could happened?

Various 64-bit compiles of Spark 0.3 were merged together in our database, so now you need to download games of "Spark 0.3 64-bit 4CPU" from the CCRL 40/40 Games page: Spark_0_3_64-bit_4CPU.commented.[477].pgn.7z

the same for another shredder 12 settings like Deep_Shredder_12_64-bit_OA_Off_4CPU.commented.[268].pgn.7z,

This file is available from the CCRL 40/40 Games page: Download.

and I download the last update of total Database (40/40) but when I filter to search, for say Rybka 3 64 bit 4CPU I get only 1400 games, and in the engine section the same Rybka have 1470

I just checked, the latest complete CCRL 40/40 database (CCRL-4040-commented.[231789].pgn) contains 1470 games of "Rybka 3 64-bit 4CPU".

so it could be nice for all your "customers" that each type of download have the same update, don´t u think so? Tnx in advance!! and great work Graham!!

The great work is not only his, see the Thanks page.

oh by the way , why CCRL don´t test any Rybka Winfinder version yet??

It did not attract our attention.

Regards

Best,
Kirill
