Re: NNUE

I would invite all Draughts programmers to have a close look at http://www.3dkingdoms.com/checkers.htm . A checkers program GuiNN Checkers 2.0 based upon a NN. Also source code included, including NN training tools. At least i have seen that Rein is already digging into the details. Rein, maybe you ...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzystof, you are right my program uses fixed time to do the move. This is not optimal, and others use better time management. The way Damage calculates the time needed for the search is simple, the GUI communicates the number of moves left and the time left, and based upon this info Damage calculat...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzystof, if you have a theory then please share it. As you have played all the games, you might have seen something strange. As the results on your computers and mine are exactly the same, I suspect that Jelle is right, and it is related to the hash-table and multi-threading, and maybe the way i ab...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzystof, sorry i did the test with the position after the move 23-29, now i can confirm i have the same results as you.
So a strange bug which for whatever reason occurred several times during the tournament.....
And which was not really obvious during the DXP matches.

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzysztof, in my case the move 19-23 is played after 28368395 nodes 25 ply, and 37194237 nodes 26 ply. Score is the same 0.00 But i do not have an AMD machine, but it should not make a difference? Here the dropbox link, could you check if you use the engine version with the same date? https://www.dr...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Jelle, basically that is what is also expect, as the most tricky part is the multi-thread search (in my case YBWC). But my puzzle is why does it occur so often in the tournament (and only black, but 6 might not be significant) and not so frequent in DXP matches. Therefore my request to you for a DXP...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzystof, without any doubt i will share the next version of the Damage engine. However my focus is to understand some results of the current version of Damage. The 2 draws within a won position, due to move repetition, is clear. As I mostly test against KR, the endgame is never played and the progr...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Jelle, as i struggle to replicate the tournament results with black, could you play a 158-games DXP match with SB against Damage. If you both want to use 6p DB, then change the 5 for the bb-cache into 1. bb-cache = 1 bb-size = 6 bb-preload = 6 Maybe with another program (as i normally use KR), some ...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzystof, but in general i have deep respect for the way you organize the tournament.
I'm sure I'm not the only one, so thank you for that !!

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Krzysztof, the recent version 15.4 plays in a 158 games match against Kingsrow 1.62 8 losses and 150 draws, with settings 2 min/75 moves (in the tournament i participate with the 15.3 version). So you are right the new Kingsrow version is better , my expectation 15-20 ELO difference with Damage. But...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

Strange, as you also played (recently) a 158 games match Damage against Kingsrow with DXP. The result ( 1 min/game): Damage 15.3 x64 - Kingsrow 1.61 x64 0 wins, 5 losses, 153 draws, 0 unknowns So I'm the first one to admit that Scan and Kingsrow are stronger, but i don't have a good explanation for ...

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

I don't have 16-core machine like you, so please help me what is the interesting result :).

For my understanding, how do you set the time for damage, with the Damage GUI?
With levels normal game?

Re: The Unofficial World Championships Of Computer Programs In International Draughts Blitz 2020

I also analyzed Scan - Damage, here the evaluation score during the game was also flat (around zero). I initially thought that the beautiful Scan combination (ending with 38. 26x10) was defining the outcome. But in fact the next move from Damage was completely wrong 38. ..... 28-32 should have been ...
