For comparison SF 16.1 gets 41 plies and with 6 cores 45 plies.
1 core, 1 minute, depth 50, is fast in my opinion.
Or many cores, 30 seconds or faster, depth 50.

I am curious to know how this is done. Am I doing and interpreting it right?

Code: Select all

go depth 45
and then I got

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Latest Stockfish has impressive search depth

Post by royb »

I noticed the search depth improvement when running the May 13 version running on my laptop. That version runs at TCEC coincidentally. There may be other even earlier versions that have that characteristic - I haven't checked them though.

The NPS seems a little bit lower, so perhaps it is the NNUE net that is making the difference? I'm guessing here of course because I'm not educated about how NNUE works.

And it could be NNUE changes plus efficiencies in the search of course.

And upon closer examination, the May 13 version is definitely faster than the official 16.1 version, but the May 30 version is faster even than the May 13 version.
