Stockfish Handicap Matches

[Rebel]

Stockfish version 11 is elo rated 3534 on the CCRL 40/2 rating list. We play time handicap matches as long as it takes that opponents can beat it. The first match is played at equal time control (40/10) and 1000 games. Thereafter we increase the time control of the opponent with a factor two (40/20) and 800 games. We repeat this process till the opponent finally is able to win or till the maximum of a factor 10 is reached.

I think you could achieve the same data, with much more games, if instead of increasing the time factor of the engine, you decreased the time factor of Stockfish.

The scaling curves up and down aren't the same.

You'll probably need to go to factor 20 (5%) or even 100 (1%) ... if you want to include all 3000+ engines, depends on your target (in this case, decreasing SF time is easier ...)

Yeah, but what's the difference? Can one curve be mapped into the other?

Like, play a Booot 6.4 v Stockfish 11 match where Boot gets a factor of 1, and Stockfish gets a factor of 1/10, and see how it compares to the Booot 6.4 Factor 10 ones. If you can extrapolate the differences then you can build a curve that tells you how Boot Factor 20 will perform by playing Factor 1 v Stockfish with factor 1/20 in a fraction of the time or allowing you to play twice the games.

Added a handicap factor of 100, fun with the known names of the past and/or former rating list leaders and world champions.

Progress has been amazing...
