Re: Where are the funs of Leela?

If they figure out how to get GPU cards the do alpha beta, or they get GPU cards to do full recursion without wait, then the Alpha beta searcher engines will mop the floor with the NN engines, laughing all the way to the bank. The compute cycles of the GPU cards are orders of magnitude higher than ...

Ed, NB that LCZero “node” counter actually counts playouts, not nodes. To convert to normal nps, multiply by the average line depth.
I wonder if that's how Alpha counts too.
Allegedly so, but in both cases I am secondary or tertiary source, only repeating what someone else wrote.

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

My suite is rough and unpolished. Question about your suite, how long does it take (an estimation is also ok) to analyze your 200 positions at (say) depth=5 with a 256x20 NN on your (GPU) hardware. Not sure about depth, I am testing at fixed time, but depth=5 is really low for current Lc0 on my GPU...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

My suite is rough and unpolished. I guess 10% of my solutions are wrong, and another 10% dubious. But seeing Lc0 at longer times on strong GPU solving about 80%, I get confidence in both: my suite is not totally useless AND in that Lc0 in the openings is a positional phenomenon . I guess the openin...

Re: open files and diagonals

Hi, STS says that Micah could be improved regarding "Open Files and Diagonals". Now someone told me that an open file in this case means a file without any pawns on it, not neccessarily any other piece-type (correct?). Is the same true for the diagonals? In old code I found a check for files withou...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

I just want to say that I think the distinction between "tactical" and "positional" problems is rather arbitrary and not so useful, because in real chess games good positional moves are found by tactical details. For example, let's say that rook on the 7th rank is usually good (with whatever condit...

Re: WCCC vs TCEC Chess Engine Competitions..

Way past time to get off the old anti-ACM bandwagon, Way past time to get off the old ICGA bandwagon also unless they reinvent themselves. Pretty sad comment. The main thrust of the ICCA (then ICGA) was to foster interest in computer chess. They STILL provide that service via the annual mind games ...

Re: WCCC vs TCEC Chess Engine Competitions..

Wccc is and has long been utterly irrelevant. A few Europeans will disagree. Their opinions are irrelevant also. Wccc is watched by a tiny smattering of European chess nerds. Tcec is watched by hoards of enthusiasts. Wccc does not even follow their own rules. I find them utterly repulsive, despite ...
