Re: Playing the endgame like a boss !!

I don't agree. In any game a faster win is preferable over a slower win. That is not domain-specific knowledge any more than that a win is preferable over a loss. It is not enough to know how to reach a position from which you theoretically can force a win if you do not know how to actually convert...

Re: deepmind's alphastar beats pros in starcraft ii

They picked Starcraft because it is the most famous "milestone" game still not conquered. If you check https://xkcd.com/1002/ and know about Sharp, Alphago, Watson and Libratus it becomes quite clear. The criticisms of AlphaStar are somewhat valid, but similar to the ones moved towards Alphazero. De...

Re: Why Lc0 eval (in cp) is asymmetric against AB engines?

https://i.postimg.cc/sXvF4P8G/Lc0-04.jpg Lc0, to smaller degree, still has difficulty converting even large evals it shows. It exhibits a sort of Contempt of some 60cp. SF10 has an in-built Contempt of about 20cp. This difficulty converting of Lc0 is probably again related to bad endgames and occas...

Re: Scaling of Lc0 at high Leela Ratio

Including the error bars in the graph, the shape of the scaling could easily be a parabola in the other direction (i.e. with the minimum where you have the maximum). Also, comparison between Alphazero and Leela should consider that the match was with SF8, not with SF10 (more than 100 elo difference)...

Re: Official: Lc0 is the strongest engine :)

While clearly LC0 is not the strongest engine (that title is currently with Stockfish), I don't understand why we shouldn't "trust" and engine which in 7 months became a member of the "big 4".

Re: Official: Lc0 is the strongest engine :)

GPUs have been improving much faster than CPUs. If this continues, it'll get better and better for the GPU engines... Ofc they were improving much faster when 9xx series was on 28nm, while Intel is already 4 generations on 14nm (10nm Cannon Lake is a total failure since Intel can't make a reliable ...

Re: Official: Lc0 is the strongest engine :)

It is actually one of the path to improvement.
Dedicated Alpha / Beta "blunder checker", perhaps running on CPU which usually have spare cycles for LC0.

Re: Does LC0 get hardware advantage?

I think that a far more interesting question than which type chess engine gets more NPS per MIP is which gets more Elo per dollar. After all, that is the true goal. You are completely correct ! Very few people care about what is "fair" for some shaky definition of "fair". Many people care what perf...

Re: Lc0 v18 rc2 for 2080 Syzygy implementation

The Tablebase fixes are already in the release 18.1 which will be used for TCEC cup and CCCC2.

Also the "minimaxing back-up of the values" is already in the works, with the name of "certainty propagation".
