CCRL 40/4 lists updated (9th February 2013)

[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/ (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 40/40 and 40/4 lists are updated once every two weeks and alternately to each other. The FRC list is updated when a new engine or engine version is being/has been tested.

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 download databases by month or ECO code are only updated monthly, but the total games database in its entirety is always available.
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.

Just a heads-up, I checked the 40/4 list, but it still says Jan 27. Instead, the 40/40 list is now dated Feb 9.

Hi Carl,

try refreshing the page.

Graham.

Thanks, Graham, it works now Great job with these lists!

While I was looking at the 40/40, I noticed Ivanhoe was de-listed from the main list since presumably it's not the strongest 'straight' Ippolit any longer (Bouquet 1.5 is rated higher). This actually makes sense, as it unclutters the list at the top. Frankly, Strelka deserves the same fate... . At least, they'll still appear on the Complete list no matter what.

Yes, but what fate exactly. There are many versions
Strelka 5.5 64-bit
Strelka 5.5 32-bit
Strelka 5.1 32-bit
Strelka 1.8
Strelka 1.0b

5.1 and 5.5 part of the Ippo family, 1.0b and 1.8 part of the Rybka family ?

[carldaman]

Ray, I was mainly referring to the Strelka 5.x series. It may not be a stretch to say it is just about the same as having Houdini 1.5 in there, if my understanding is correct (from what I've gathered). But far from me to suggest any further controversy, as I could be wrong, too

Houdini is rightly a family of it's own. If the Strelka author admits that Strelka is RE Houdini then it should go in the Houdini family.

[velmarin]

There are many more who would like Ippolit, only to be saved from the burning.
From the top, Houdini and Critter and more.....
The list would be weird ...

Yet the openness that makes CCRL is praise. Very Thanks for you works.


If it is another page, I would put a list with the best version of all engines tested.

Thanks.

Hi Graham,

I just say that the site was updated on Feb 17, and quite a few Myrddin 0.86 games have gone missing? Last week there were 282 games and now there are 82. Were those new games disqualified somehow?

Hi John.

I think you're confusing 40/4 with 40/40.
The 40/40 list has just been updated.
