CCRL rating lists updated (17th September 2011)

[Graham Banks]

The purpose of our rating lists is provide engine authors and enthusiasts with a general comparison of engine strength. We also provide other data that could be of interest.
For various reasons, there may be some engines that do not appear on our lists, 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. However, where there is controversy surrounding an engine in our lists, we have indicated this.
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, but you will need to remove the .live from the links if you wish to access these (for example http://computerchess.org.uk/ccrl/4040 ). 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.

Mr.Houdart won't answer because he already knows that Houdini 2.0 is actually a slightly modified Houdini 1.5a with a grant of salt here and there to make some bucks....nothng wrong with that of course if we eliminate the termin "honesty" from our dictionary....

There's quite a lot of data from 1 to 6 cores that supports the fact that Houdini is about 20 Elo stronger than Houdini 1.5.
But with this level of Elo improvement, there's bound to be some tests that show no progress at all, whereas other tests will show a lot more than 20 or 25 Elo.

You have a long history of stupid speculation and idle claims about Houdini.
Last year you claimed I would disappear from the engine scene - but then I released Houdini 1.5.
Earlier this month you claimed that I would never release Houdini 2 (and next day I actually released it).

I don't know what drives your incessant negativity and senseless speculation. When Rybka was the strongest it was directed at Rybka, now that Houdini is #1 you've turned into a Houdini hater...

Stupid speculation
How about the results of Houdini's performance both in the CCRL & CEGT testing groups,ah

Well,you are enough thick skinned not only to stay in the chess scene without telling the truth about Houdini's origin which is an improved Robbolito chess engine,but to even go further and sell it to the public with included spyware code in it sending information to your stupid site snatched from the unexperienced users without alerting them.....

That's what drives me against you and your engine,not because it's number one,for now,but because of your obvious dishonesty....

As for Rybka,all the members here know my position toward it and it's author not releasing a promised bugfix version and not giving a damn about his customers....after he released Rybka 4.1 as a bugfix,I stopped my roaring....

I don't hate Houdini,it's a fine piece of art,I hate it's lying author,that's all....
At least I have the guts to stand here and tell you that in your face....

And to quote myself from my Facebook page:
I don't play games.What you see with me is what you get.I would much rather be hated for what I am than loved for something that I'm not....

Try to apply this in your life Robert and maybe you'll be more respected regards,
Dr.D

[Houdini]

You have a long history of trash-talking Houdini and its author on several forums, without being hindered by any knowledge on the subject.
Apparently you're proud of this infantile behavior, this is your good right, the internet is free...

The thread was not intended to insult you or to try to get the upper hand for myself....just exposing some simple facts....

Believe me,it's better to hear it from people like me who will tell the truth in your face rather than hundreds of them throwing mud behind your back....

Oh,knowledge I have more than you can assume....
Anyway,let's call it a day regards,
Dr.D

P.S.The internet is not free....to think so it's more than naive to say the least....

Please just look at your own posting history about Houdini. What you call "simple facts" and "truth" are in fact mostly idle speculation, slander and trash-talk. And you seem to be very proud about this...

[Adam Hair]

To be honest, the CCRL has not run enough games to discern if v2.0 is stronger or weaker than v1.5a. The results so far can not be used to refute the claim of +20 Elo for v2.0.
