No - because a person is honest.
Good to know that you are not interested anymore, I wish you good luck!

It surprises me that changing the hash table size barely affects the results.

That Ares version you have is just an untested experimental build I made for Sidiki a very long time ago, which you really wanted a copy of. Turns out it has a repetition detection bug, so it misses a draw every now and then. I've fixed it in the latest version, but I'm holding off on releasing it since there’s still a lot of other stuff I want to polish, and that takes time. The new version also uses a 7P EGDB instead of 6P, this won't make a big difference, but ocassionally it could help.

I also want to advise you to run tests like these on two computers. In my experience, running tests like these (with huge endgame databases and pondering) on a single computer makes the engines influence each other in a bad way, especially under Windows 11 (which is the worst OS Microsoft has ever produced).
Since when do games using dxp take place on two computers? You write nonsense and strange things, Joost. Have a nice day, Joost.

Hi Sidiki,

I probably know which engine this is. Can you tell me the time-control you used?

It's like this topic says 'Internet engine matches', this means two separate computers talking to each other via Internet or via a LAN.

The topic has already been discussed - using dxp you play on one computer. Unless someone else comes up with something else. Have a nice day Joost.

I can't help there seems to be some lack of knowledge in this conversation, for me it is clear, I'm done with it.

Thanks for the info!

It's a very good result considering Kingsrow is difficult to beat under these 'bullet' conditions.

This afternoon I played a match against Kingsrow using Ares v1.93; this version is virtually identical to Ares v1.91 with a few bug fixes. Both engines were single-core, no book, 7-piece endgame databases (EGDB), with a time control of 30 seconds for the entire game plus a 0.5-second increment per move. The final score is 158 draws.

On my machine, Kingsrow does 24 to 27 MN/s single-threaded, while Ares does 9 to 11.5 MN/s with its (slow) network.

Ares uses a single network (no separate middlegame and endgame networks), with a total of 6,705,561 floating-point weights.The current network was trained on only 150M positions labeled with the game result (-1, 0, +1), so this number of positions seems to be sufficient to train a strong-playing checkers network.

I have attached the games of the match.

Hi Joost,

Great, all draws. Ares done well. I plan to run a tournament these day and i will be glad to include this latest version.
Congratulations.
