CCRL update (27th June 2008)

[Graham Banks]

The June 27th update of the CCRL Rating Lists and Statistics is now available for viewing at:
http://www.computerchess.org.uk/ccrl/4040/

Our standard testing is at 40 moves in 40 minutes repeating and our blitz testing is at 40 moves in 4 minutes repeating, both adjusted to the AMD64 X2 4600+ (2.4GHz).

Currently active testers are:
Graham Banks, Ray Banks, Shaun Brewer, Kirill Kryukov, Tom Logan, Andreas Schwartmann, Charles Smith, George Speight, Gabor Szots and Chuck Wilson.


During the early stages of testing, an engine's rating can often fluctuate a lot.
One should also 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.


Our 40/40 list usually gets updated during the week also and can be viewed here:
http://www.computerchess.org.uk/ccrl/4040.live/
However, no game downloads are available from the live link.

The links to the various rating lists can be found just beneath the default Best Versions list.
For example there is a 32-bit Single CPU list.


Our latest 40/4 ratings can be found at one of the following links:

Our FRC 40/4 rating lists can be found here:
http://www.computerchess.org.uk/ccrl/404FRC/

Only those engines that can play FRC through the Shredder Classic GUI are tested.


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.
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.

How come the lowest rated engine there is 2018? Don't we/you ever use littler engines with much lower ratings?
Just currious.
I am about to start a small trounement, very unusual to be sure. I don't think anyone has ever done what I am about to do.

Hi Bill,

main reason is that there are already heaps of engines to get past 200 games, with newer versions of many coming out fairly regularly.
Engines that we can't guarantee will get past 200 games usually get "killed" as in removed from the list.

Cheers, Graham.

Yes. Shaun has to ring the provider back in 5 hours to get it sorted.

None of us have purchased it yet, so it might remain untested.
It's too expensive having to buy all commercials. Some engine authors help us out in this regard, but not all.

I wish you guys could by like a group copy..Purchase 1 for the regular price and a small fee of say 10 bucks for each additional license. You should try emailing Lex though..
