From Ed I got the information that the current Scan nnue implementation does not work in hub mode. I checked that, and he is (as usual) right. As I mainly play DXP matches with Scan nnue, I only included the dxp option. So I will fix this during the week, and post an update. Bert Thank again Bert, ...

Sidiki, the exe file which you need is in the folder x64/release, scan_31nnue.exe (1/16/2021). If you already have a working Scan configuration you can just put it in the folder where the original Scan is. The network (nn_20210110.gnn, 1/10/2021) is in the folder scan_31nnue/data. You need to add t...

I also checked the most recent version of Scan nnue. The match against Kingsrow was with the traditional settings, so 1 min/65 moves, 6p DB, 6 cores no book. Result (perspective KR) 3W, 0L, 151D, 4U I analyzed the 4U, with outcome, game 53 draw, game 133 win Scan nnue, game 141 draw and game 147 al...

Herewith the link to the dropbox folder with the sources of Scan nnue. I will post later some side notes. I would like to thank several people who without this was not possible. First of all Jonathan for starting to implement nnue in his checkers program, and I used his code as base , and you can s...

The test with multicore seemed to work. The usual settings 1 min/65 moves (so equal time control), 6p DB, no book, and both 6 cores. Result KingsRow - Scan nnue (perspective KR): 158 games, 6W, 0L, 152D, Elo difference is 13. During the weekend i will try to make the Scan nnue source available for ...

Sidiki, you are welcome. As this is the last day of my Xmas-holiday, from now on progress (if any) will be much slower. Sorry for that. Bert Hi Bert, Happy New Year to you and others programmers. Understood, we will waiting for the new progress done by Damage. What can explain this gain of strength...

Sidiki, here they are.

There were 2 unknowns which were both a win for Kingsrow (game 48 and game 84), for which I corrected the scores in the file.
Result 22 W Kingsrow, 136 draw, Elo difference 49.

Bert

Thanks very much Bert.Thanks

Sidiki

With 256 neurons in the first layer the match result was (perspective KingsRow) 22W, 136D. Elo difference 49. Not sure if this is within the margin of error, but if one thinks in a positive way, slowly improving day by day :D Bert Great result with Damage's NNUE; i think that, as i said, we must ha...

Sidiki, no the approach is different and more in line with Stockfish NNUE. Bert Hi Bert, Understood, so if, if you can take time to write an answer to this perhaps stupid question from me, i want to learn; i will be very glad. I suppose that you Bert, are a draughts player, and you want to do a NNU...

Sidiki, thanks for your post. In all honesty I doubt that with NNUE one would get better results compared with the current Scan pattern-based evaluation functions. They are extremely efficient and fast, so I don't know if we would even get close. But working on NNUE is fun, and I like the fact that...

Sidiki, and to reply on your other question. I used the previous match file and extracted a file with positions, and a file with result labels (based upon the previous Damage Evaluation, scaled with a Sigmoid function). You could say that in this way you project the old evaluation function into a n...

Hi Bert,

This's very interesting. I see that there's an improvement in Damage's result against Kingsrow.
Please, how it's done the learning?, by auto-playing; or you wrote a new one algorithm.

Thanks,

Hi ED,

We hope that most of you on this forum will take part to this tournament, to fight again TD King, or Cerberus we don't know if they, the programmers of these engine, improved them.

Sidiki

I think that all it's clear now, because, excepted if it's a bug.
if no if you set 3min/75 moves, any program excepted Damage 15.3 will respect it

Krzysztof, Before doing all these sentences for draw adjucating, try Scan vs Scan or Mobydam vs Mobydam, you will see that they will play until, if it's win or draw, the human that you are will be convinced of the result. I know that Kingsrow stop the game even with 4 or more pieces on the board, Ju...
