CCRL rating lists updated (19th February 2011)

Post by Graham Banks » Sun Feb 20, 2011 4:28 am

The purpose of our rating lists is provide engine authors and enthusiasts with a general comparison of engine strength, plus other data that could be of interest to them.
For various reasons, there may be some engines that we have not tested, therefore it is useful to look at other rating lists as well as ours.
The inclusion or exclusion of engines in our lists should not be taken as our group making a statement about their legality or status.
We test chess engines for our own enjoyment and receive no payment for doing so.

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

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.
The current ELO ratings are 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.

Thanks to all testers who contributed to this update.
