Bravo to CCRL for reporting stats like draw percentage and white score at the top of every page.
But these are apparently for all games ever played at a given time control.
I wonder -- and pardon if this is common knowledge around here -- Has the draw percentage increased among top engines recently? Has the white score changed?
I think this would be most interesting to know for top engines at the 40/40 time control...

Re: CCRL draw percentage?
I had a look at some PGNs from CCRL
No real evidence these stats are changing, but only 4 data points here. And it's not clear what opposition is being faced. Are most CCRL bouts Swiss? That would be good.
I've heard the draw percentage in later TCEC rounds has been increasing, such that they're moving to an 'all possible openings' format next time. Are data available? I've always found the TCEC website unnavigable...

Re: CCRL draw percentage?
Thank you, Dan! That certainly looks like evidence draw % is increasing. Not so clear what's going on with white's advantage.

Re: CCRL draw percentage?
Assuming chess is a draw and that we're within ~ 400 Elo of perfect play with current engines (and closing fast), I expect both the draw percentage and white's advantage to increase.
Intensifying competition can also cause them to increase. White's advantage increases with the average Elo of play and decreases with the Elo difference between players.
Competition among top engines actually fell during Rybka's heyday, as older projects weren't willing or able to adopt tuning-driven development practices. But the field has become competitive again in the past 2-3 years, with almost no Elo difference between the top two engines at long time controls.
As long as the Elo gap between engines is small, white's advantage should be a function of their distance from perfect play (reaching 100% in the limit). Same with the draw percentage.

Re: CCRL draw percentage?
The CCRL data is a bit of a black box until the the Elo gap between opponents is characterized. The number of pairings between strong and weak engines could vary from year to year.
The data should be sliced into sections by Elo.

Re: CCRL draw percentage?
Of the 627,825 games in the current CCRL 40/40, there are (by my count, there may be more) 4,682 intra-family games. Intra-family games have a higher draw rate because of the similarity of analysis.
The intra-family games:
White Wins = 1229 ( 26.25 % )
Draws = 2758 ( 58.91 % )
Black Wins = 695 ( 14.84 % )
White Pct = 55.7 %
Black Pct = 44.3 %
All games, including intra-family games:
White Wins = 218616 ( 34.82 % )
Draws = 247209 ( 39.38 % )
Black Wins = 162000 ( 25.8 % )
White Pct = 54.51 %
Black Pct = 45.49 %
Another issue is the Elo distance between players.
For the entire 627,825 games:
Elo Distance: Maximum = 852 Average = 72.276

Re: CCRL draw percentage?
The average opponent rating is already there for each engine.clumma wrote:The CCRL data is a bit of a black box until the the Elo gap between opponents is characterized. The number of pairings between strong and weak engines could vary from year to year.
The data should be sliced into sections by Elo.
If you click on the engine name from the list, it will bring up the opponents played.

Re: CCRL draw percentage?
Whoa, I never knew you could click on the engine names! Cool.
I put some draw percentages together for the nearest opposition of some well-known engines:
"Elo" is the Elo gap.
Is draw percentage increasing because we're nearing perfection, or because of different engines (contempt etc), different opening books and tablebases...?
