The latest CCRL update (31st August 2024)

[Ray]

Yes, as I said, different tester, different hardware, different book, different GUI and even a different compile of Stockfish 15.1. But the large error margins are surely the dominant factor. +/- 20 Elo or so on each engine with the low number of games.

Stockfish 15.1 on one thread was tested:
Intel i9 10900
bmi2 compile
Pohl SuperGM 4Moves book
Cutechess GUI

I've found a bug in Aprils Rating List: https://ccrl.chessdom.com/ccrl/4040/gam ... 47].pgn.7z
EloValues for three engines seem to be missing:
KnightX 3.7b 64-bit - , e.g. in Round:874.2.29
Zangdar 2.15.03 64-bit - e.g. in Round:875.1.883
Renegade 0.10.0 64-bit - e.g. in Round:875.1.932

I haven't checked any other files yet, and don't know whether this bug is already known, but hope I can help with this reporting.

[Ray]

Possibly because there are not enough games for a reliable rating.

You mean games played in April, not the April ratings list ?

[Peter]

Yes, it's in the PGN-Files of the games (the one I linked above), not in the rating list.

Hello, author of Austerlitz here.
On 4 December I shared Austerlitz version 1.4.7 and asked for testing it, but I still haven't got any return information about it.
Actually, I hoped to see it appeared on the next ranking list. Could I know how Austerlitz testing is going and when could I possibly expect to get estimated elo of the engine? I noticed given ccrl links don't work, at least on my device.

Fritz 19

Ginkgo Valencia 1.01.

Nobody knows it, could you link Ginko to Fritz ?

[Graham Banks]

Fritz 19

Ginkgo Valencia 1.01.

Nobody knows it, could you link Ginko to Fritz ?

I'm pretty sure that most are aware, but it's in the engine notes anyway.

[othoma]

I am sorry, everybody knows official Fritz, not Ginko , so everybody is searching now Frtiz 19 especially if there is Fritz 18 in CCRL.

The latest CCRL Rating Lists and Statistics (17th August) are available for viewing from the following links:

www.computerchess.org.uk/ccrl/4040 (40/15 and 15m+10s)
www.computerchess.org.uk/ccrl/404 (BLITZ 2m+1s)
www.computerchess.org.uk/ccrl/402.archive/ (BLITZ 40/2 Archive)
www.computerchess.org.uk/ccrl/404FRC (FRC 40/2)

Our 40 moves in 15 minutes repeating (including 15 minutes with 10 second increments) and 2 minutes with 1 second increments are both adjusted to the Intel i7 4770k (3.5GHz) using the Stockfish 10 64-bit benchmark.
All of our current testing uses AVX2 compiles where available.

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 inclusion or exclusion of engines in our lists should not be taken as our group making a statement about their legality or status. Where there is controversy, it is usually mentioned in the engine notes.

Thanks to:
- all of our currently active testers (Graham, Gabor, Basti, and Shaun).
- Ray who ran the time-consuming weekly updates for a very long time, a task that has been taken over for now by Basti.
- Jay Honnold for both the tournament viewer and for hosting Graham's live broadcasts.
- all engine authors.
- Anton Mihailov (Chessdom.com) who graciously hosted our website for a long period of time.

40/15 and 15m+10s testing this week will include (Thanks to Graham. Live broadcast given where applicable):

Live broadcasts of some Gauntlets can be made available upon request.
