Re: Stockfish 11 at 120k nodes per move

Good and bad things. Mephisto to UCI works and the emulator automatically adjusts its speed to my system so I only need to give it a 40/120 TC and will run and also leaves behind a log. Bad thing is that unless the option is hidden somewhere I can't speed it up. And the strongest Mephisto it offers ...

Re: Smoothing SF progress of nextchessmove

I guess that even with the bad version the correlation coefficient is very close to 1, which means the progression is very nearly linear. Since Elo is exponential, this is excellent evidence of constantly exponential progress in the strength of Stockfish. That is really pretty amazing. Too bad our ...

Re: FGRL 60 sec + 0.6 sec rating list - Stockfish 11

Interesting results from Fizbo.
Guess that little NN does help with winning games.
Or maybe it's just noise.

Re: Stockfish 11 at 120k nodes per move

The question is also if fixed nodes per move has to be exactly 18K nodes per move or maybe the engine is allowed to use at most 18K nodes per move at move 1 when nodes that it did not use can be used in the next move so with 18K nodes per move the engine can use at most 18k*n nodes for the first n ...

Re: Stockfish 11 at 120k nodes per move

What is the meaning of "fixed nodes per move", though? Because when you force the engine to play like that, you're forcing it to abort the search on some random point of the current iteration, and then I'm not sure what's the best strategy to follow when choosing a move. Suppose it's on the middle ...

Re: Stockfish 11 at 120k nodes per move

Jeroen has a bunch of opening collections that should work just fine for such a test. However, the thread has devolved into multiple different ideas. 100nps is a different thing from 100 nodes total. Just as is 2K or 5K total nodes much different from 2K to 5K nodes per second. All of the different...

Re: Stockfish 11 at 120k nodes per move

Thank you Larry for your interesting input. To complete, my initial post, I ran SF11 @ 120knpm vs SF11 @ 360knpm. It appears that by eyeballing the doubling at 200 elo in that npm range I overestimated it somewhat. My data for SF from may is 180 elo from 130k to 260k and 130 elo from 260k to 520k. ...

Re: Stockfish 11 at 120k nodes per move

So this is basically some empirical evidence that my claim of SF at 100 n/s = GM level was right. With +-2400 being at the low end of GM level. People underestimate engines. Did you omit a zero? A thousand n/s is at least in the ballpark, a hundred is ridiculous. I have the Revelation chessboard wi...

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

Yes, SF hasn't become any stronger at 1s+0.01. This is particularly related to this patch : https://github.com/official-stockfish/Stockfish/pull/2260 It lost 40-50 elo at 2s+0.02 ; lost ~4 elo at 10s+0.1 @ 1.6mnps ; gained ~1 elo at 20s+0.2 ; gained ~5 elo at 60s+0.6 and around ~12 elo at 180s+1.8....
