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

Surpassing Deep Blue's 200 Million nps. But 22 years later... But now, Stockfish at 1 Mn/s is stronger than Deep Blue at 200 Mn/s. 8-) Stockfish at 1 kn/s is stronger than Deep Blue. Is it? I’m not sure that’s right Stockfish should be GM level even at 100 n/s classical time control.

Re: How many Qubits need to slove chess?

What do you mean with perfectly? 32 piece tablebase kind of perfect? Yes. Or weakly solved like checkers? In that it only has the perfect solution from start (initial position) and only plays perfectly if opponent also plays perfectly. Ummm, the checkers situation is different. "The crucial part of...

Re: How many Qubits need to slove chess?

A/B converts to minimax. Just needs some time. By "solve", we do mean both perfectly and in the lifetime of the universe. (There are more formal ways of putting it in computer science.)

We already have alpha-beta pruning, chess is solved. Now we only need time.
That's not solving unless the pruning is perfect, which it cannot be unless you've solved chess by other means.

mwyoung: the way i interpret your replies is that you're afraid of sacrificing speed (modest speed penalty), something that is most necessary when running with ponder enabled.

Re: CCRL scaling versus human player

I asked a friend of mind who is rated not so high, but still not so bad : 1900 FIDE to play against Igel 1.2 and Igel 1.3 with 1 thread, 1 mb of hash and not tablebases and no book. The result is that he had absolutely no chances, but most games were quick time controls. It may be worth to test Sha...

Re: SPCC: Testrun of Stockfish 190531 finished

I wonder if Allie on a small net vs Leela on the same net would change their ELO relative to each other. Since Allie's search is so different, does she want a bigger or a smaller net (than Lc0?) On cccc Allie plays with the Leelenstein NNs, which have normal 20x256 size. Perhaps, I will try a bigge...
