Re: Crystal solves a 74 mover ... in 11 seconds

I can confirm the latest version of Crystal no longer holds on to the mate score. This is likely due to some underlying changes in upstream stockfish which have been merged. I'll investigate and see what I can do...

Re: Stockfish with and without contempt

If you create a git branch with the change, you can just pull master into it and it will auto merge as long as no changes have been made to the contempt code upstream.
but I need the correct score.
Well, the chances you aren't getting that are about the same regardless.

Re: Stockfish with and without contempt

I really don't think it can be quite as bad as you make it out to be (if used reasonably). The eval of any engine is already uncertain (other than hard cutoffs). So if one has uncertain nodes that eval as draw, they could just as well not be. Which is why SF's evaluate.cpp has received many patches ...

Re: My predicted 3rd Gen threadripper prices

I would guess they will want something at the $999 price point, so I would guess that for the lowest end, $1199 max. Top tier, I'd go $2999 max but I'm less certain of that. The 28 core skylake-x is $2978, so yeah I'd go upper bound of $2999 but likely less.... maybe $2699? As for site reliability w...

Re: Hard pawn endgame

This is difficult. The best problems solver = Crystal is clueless after 10 minutes. It don't reach enough depth I think. It is a good test position. Unfortunately, Crystal has no mechanisms in place to deal appropriately with such positions. However, it is pretty clear how one might address the iss...

Re: LCZero blunders in TCEC cup 4

It depends on what input features the NNs have access to and how they are trained. For A0, it was certainly possible that such an effect occurred (due to the presence of movecount). For LC0, the likelihood & potential impact is much less as it does not have movecount as an input. It does still have ...
