Re: Damage NNUE - future request

Krzysztof, Damage has a very simple time-management, where (more or less) all moves get the same time. Unfortunately when Damage gets into the late middlegame, then often (due to endgame databases), the move is played very fast. I know i need to change it one day, but the risk it that if is spent to...

Re: Question about endgame databases

Ed, first of all thanks for sharing this huge effort with the draughts community. As, although it might not be rocket science, it takes lots of resources and time. I guess your arguments make sense. In the chess world this is already common practice, as all programs (or many) use the Syzygy tablebas...

Re: NNUE

Krzysztof, the advantage of NNUE is that in runs on the processor only, so also in the chess world one use NNUE without graphics card (example Stockfish). Programs which use far larger neural networks and MCTS (like Leela-zero) use a graphics card. I expect that due to latency NNUE on a graphics car...

Re: Processor for draughts

As Joost pointed out Intel might introduce new HEDT processors in 2022 based on the "Sapphire Rapids" architecture.
Not only do these processors have more cores, it also contains AMX (Advanced Matrix Extensions) which will give a huge performance improvement for NNUE based programs.

Re: Evaluation Function Fuss

Interesting to read old posts (10 years ago).
Especially when we see the progress being made in evaluation functions (and alike).

Re: NNUE

Krzysztof, i understand the situation. Basically when the engine thinks, you should not be able to move the pieces (in your case the black pieces). So what is your preference? I can change the GUI that the input during engine thinking/search is not possible, or that input is possible, in which case ...

Re: NNUE

Krzystof, question when exactly do you get the Error:Illegal Engine Move Message!

If you can explain me the specific situation , i might be able to see the same here, and start solving it.

I will think about pondering, and put some info in the grey box....

Re: NNUE

And if you can wait even longer, most likely the ZEN 4 based Threadripper will be introduced in 2022, and according rumours it will contain avx512.

Re: NNUE

Krzysztof,

i will make a detection mechanism in Damage 16.0, so it will use avx2 or avx-512 when available.

Krzysttof, thanks for your posts. See further below remarks/comments; * What is your nps parameter, when doing a 26 ply search from the start position? * 1) I solved the Language problem in the mean time, there was a value wrong in the French language file. I changed that and here it seems to work. ...
