CCRL Rating list update (30th April 2010)

Post by Shaun »

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 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, Gabor Szots and Martin Thoresen.

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.

1 ELO POINT!!!!! GRRRR!!

Super-congrats to Stockfish team, literally 1 point behind Rybka 3 in 40/40 is quite impressive. Hopefully Stockfish will overtake Rybka after a few more games.....

I see no basis for this hope.

Stockfish was already above rybka in the previous list and is going down.

Now Rybka3 has a higher rating in all categories of the rating list except FRC so my guess is that rybka3 is going to be get better rating also in the CCRL list.

Rybka 3 64-bit 2CPU 3181 +23 −23 72.9% −154.9 40.2% 674
Stockfish 1.7.1 64-bit 2CPU 3156 +40 −40 56.9% −37.0 56.1% 173


Rybka 3 64-bit 3153 +12 −12 71.6% −151.9 36.2% 2610
Stockfish 1.7.1 64-bit 3111 +43 −42 60.7% −65.5 49.4% 164


Rybka 3 32-bit 3098 +14 −13 73.7% −163.0 36.9% 2085
Stockfish 1.7.1 32-bit 3075 +26 −26 69.3% −123.2 47.9% 476


In Blitz Rybka3 is also leading

Rybka 3 64-bit 4CPU 3262 +10 −10 78.6% −215.0 29.5% 4871
Stockfish 1.7.1 64-bit 4CPU 3229 +16 −16 70.6% −142.9 35.9% 1367

Rybka 3 64-bit 3176 +8 −8 77.8% −217.9 26.7% 7980
Stockfish 1.7.1 64-bit 3136 +21 −20 73.9% −167.4 35.7% 893
