CCRL 40/40, 40/4 and FRC lists updated (30th December 2017)

[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)

Thank you Graham. Quick question: is there a reason why the 40/40 pure list still has Texel 1.06, while the newer has earned a higher rating (and has played more games)?

Happy New Year!

I'll let Ray answer that one.
I never really look at the pure list.

Happy New Year to yourself also.

With games played against common opponents Texel 1.06 is stronger than 1.07. That is the way the pure list works. That selection is automatic, we don't manually select which engine goes on the pure list. More games might well sort out the "problem". When a new version is close in strength to the old one, this can and does happen. ON the overall list the difference is +10 Elo.

When I was testing for these lists, the pure list was my only focus. To me it is the most important list.

Hello Ray.

I would like to know if it would be possible for me to program an engine, and then make it appear multiple times on the Pure List by changing its name in future versions.

The Rybka 4->Fritz 15->Fritz 16 case is curious. I think it would make more sense to have the Pure list show engines of different authors, even if they have the same name (so, instead of having Rybka twice as it was rebranded, you have all the Fritz engines on there that were by a different author, at least, Fritz 14 is the lastest version of its branch, nothing to do with Fritz 15, so it'd make more sense to have F14 and F15 in the pure list, and not Rybka and rebranded!Rybka.)

Thank you, makes sense now. Appreciate the response.

Hi Ray,
Sorry, could you explain more on the pure list, please. Take Texel 1.06 & 1.07 as an example. There are common opponents but there are many other not common opponents too. E.g., how many common opponents will be considered to take the best version in the Pure list? What about not common opponents, are they taken into consideration?

Thank you and regards,
Koh, Kah Huat

[Kohflote]

Hi all,
No comment from Ray / CCRL on my question about the pure list?

Best regards,

Only common opponents are taken into account when the calculations are made for which version appears on the pure list.

Some more Texel games have been played this week, introducing another common opponent, and I think now Texel 1.07 will be on the pure list in tomorrow's update. The answer is ususally in more games and making sure enough of them are against common opponents.

I'd much rather the processing was simply just to put the latest version on the pure list, whether it is stronger or not, but instead we have the rather complicated method at the moment. If enough games are played the answer is usually the same, but with 4040 getting enough games played isn't always easy.
