After 14 full moves followed by a search of 53 plies (+ elastic :) ) you would expect to have a fairly deep horizon but the score is still only 13.65.
But it's continually increasing with depth, so Uri should be happy. :)

Re: evaluation that usually go up when you are winning

Evaluation staying planted at +13 only means the engine is unable to find a clear-cut game continuation where white forces the win of more material. Which is normal because.. well, it's almost the starting position and the search tree is still immense:) Good evaluation should go up not only based o...

Re: LC0-Leela0 Rating Controversy..Whats The Strength?

What are these statements? Lc0 T40 on an RTX 2070 GPU is stronger head to head than SF_dev on 8 i7 or Ryzen cores, from not too outrageous openings. What FIDE rating that means, you guess. I think it's impossible to _measure_ the FIDE rating of Lc0 T40 RTX 2070 in a pool of human FIDE players, as m...

Re: evaluation that usually go up when you are winning

Increasing evaluations is due to the search discovering new tactical combinations that win more and more material. Aside from the missing queen, this is the opening position. The search is spending so much of its tree just developing pieces that tactical combinations just don't show up immediately. ...

Re: Is Blas, or OpenCL really the right way to go

I've been wondering is Blas or OpenCL really the right way to go for LC0 on CPU? Because when I look at the performance of Komodo MCTS on CPU, Komodo appears to be light years ahead of LC0 as far as MCTS is concerned. Of course Komodo is no match for LC0 on GPU, but on CPU, LC0 would get smashed by...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

Do you know the mean error between the actual output of the value head and the target train value? That would be dependent on the exact net you choose to examine, as well as the specific data you are comparing against. Also, not really relevant to his question or my response. Ok, so you don’t know ...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

It does not work like that. It starts with the rules of the game. It does self play to learn what things are good and what things are bad. It is not memorizing board positions. It writes out a file of numbers called a network that contains the values for different board features. It uses this netwo...
