Re: 7-men Syzygy attempt

Lets just hope 7p WDL stay below 10TB - so they fit on one HD.

Re: LCZero Accomplishments and Goals Thus Far

Because it addresses me I don't feel it would be correct to act against it myself, so I will leave the decision to another moderator.[/b][/color] I am amazed that whenever you think this forum can't sink to new lows it actually does. Also I think maybe its a good idea to let Milos post just stand a...

Re: LC0 on the WAC test suite, bad results

OK, and what's your conclusion from all that? It's no secret that Leela's weakest point is tactics, especially if you just give her FENs instead of positions with move history. If you want a tactics solver, you're simply using the wrong engine here.. Would the performance improve if you make some r...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

43 cores is better hardware then the hardware that people usually use for LC0 and if I understand correctly better than 1 GPU(I remember reading that 1 GPU may be equivalent to 10 CPU) 30+10 is longer time control then the time control that people usually use for LC0 and if I understand correctly s...

Re: The real elo of lczero is in its name

This is not coming from the test setup they used as some would claim but from this very glaring tactical weakness of MCTS that they claim is no problem. You would think Stockfish would get atleast one win from 100 games against alphazero. Why are they not playing AlphaZero on chess servers like the...

Re: comparing minimax and averaging MCTS with alphabeta roll

And yet, as scorpio-mcts-min, shows using the minmax operator even comapring scores of children searched to significantly different depths gives a +600 elo boost in chess. Even in a standard alpha-beta searcher with heavy LMR + nullmove, averaging is not used to counter for the fact that children a...

Re: AlphaZero: The 10 Top Shots

Simple logic tells you are right. 1. We always start at a position which has an unknown result, otherwise it would be useless 2. On the way of the analyis we find win/loss lines 3. As long as we cannot find/prove win/loss lines we still have to assume a draw 4. This means we have to go a much longe...

Re: AlphaZero: The 10 Top Shots

And after deep search with large hash and back-tracking to the root, Cfish says 70....Qa4 draws. Yes. In view that both lines especially the a6 lines fail - I am changing my assessment of the position. Now I believe that the position after Kf8 is very likely a draw, even if the defense is hanging b...

Re: AlphaZero: The 10 Top Shots

but because I've tried enough Forward-Backward after that, and the output given is started with already full hash from all these to me relevant lines. Fantastic, that you joined to do some real analysis! Even from 65.Qxa6+ onwards there aren't any forced lines to draw, such Queen- and Rook- endgame...
