Re: What CPU or GPU has the best time to depth?

There isn't really a meaningful way to compare time to depth for Lc0 with Stockfish. You are better off treating GPU engines as a separate domain.

Book creation papers

I was wondering if anyone could point me to some good papers about opening book creation/development. I think I want to create and implement an opening book database in Abbess that is more than lines chosen at random from a text file. Maybe with minimaxing scores like Brainfish, as well as usage sta...

Re: Is it possible to get ICGA Journal as PDF for free ?

I believe you can order them for a charge. University libraries can often get copies through interlibrary loan, as well.

Re: Lc0 51010

SF > Mephisto at same nps. I suspect it's less clear at same depth though. I am sure that you are right for big number of nodes. I am less sure if you are right if both programs get small number of nodes. I think that the main advantage of stockfish it that it has more intelligent search so it earn...

Re: Training the trainer: how is it done for Stockfish?

This last question is interesting but I assume no one knows enough to give a good answer. Is there any reason whatsoever to believe Leela would be any more accurate early on than it is in the end game? Is the talk about "endgame blunders" just an artifact of classical engines being so good in the e...

Re: about the term of equal hardware

Was adding TB availability "an advantage"? In the short term, you can argue yes. In the long-term, the landscape that engines compete in just changed, and most engines now reflect the new reality and don't bother coding special cases that TB can handle by itself. If the tournament you care about sa...

Re: about the term of equal hardware

If a tournament is run on 64-bit CPUs instead of 32-bit CPUs, are you giving bitboard engines an "advantage"? Yes : Bitboard engines can provide a 64-bit compile that will run much more quickly on 64-bit CPUs, while mailbox engines hardly gain any speed at all. No : Mailbox engine authors know full...

Re: about the term of equal hardware

The bit in bold. Just making all of the same hardware available to all sides doesn't mean there cannot be an "advantage" for one side. I don't see how anyone can argue that it must. It's a bit of semantics, I think. If a tournament is run on 64-bit CPUs instead of 32-bit CPUs, are you giving bitboa...

Clearly not a true statement in general. What part is not true? The bit in bold. Just making all of the same hardware available to all sides doesn't mean there cannot be an "advantage" for one side.
