Re: Internet engine matches

The tournament will take place on September 1, 2020. The tournament page and tournament results page are ready. This information is not yet publicly available yet. I wrote to Bert if he has time, he can make a book for his draughts engine. Jelle also probably write a new version of the program Sjen...

IMO the best way to run these engine vs. engine matches (not Krzysztof's tournament) is with Tmgr.
total 0.510 score, 15776 games, 434 wins, 112 losses, 15228 draws, 2 unk
elo diff 7.1
LOS 1.00
Excellent!

because I'm preparing for the tournament "Unofficial World Championships Of Computer Programs Rapid 2020".
Can you give the date until which programmers can send you software updates?

Re: Internet engine matches

Congrats to Ed for improving Kingsrow. Krzysztof, can you try with Scan setting book margin 0? I suggest 988 games, 1 minute/game, 8 threads.

Re: Programmer poll: TCEC-like competition for draughts engines

Sorry, I didn't quite understand that. I mean that all programs use such a tournament manager. And not just programs that have dxp and can use hub. Because it may be that some of the best programs will use and the rest of the programs will not. Yes I meant that too. I cannot speak for the other pro...

Re: Damage 15.3

What I usually do is first build a PST. No kings, balance, or game phase; just material + man position. It's very fast to learn, and doesn't require many examples. I observe that PST evals are about half way between material and patterns (which I view as higher-order PSTs), making them a good tool ...

Re: Damage 15.3

Interesting to see how filtering most draws changes the curve. We need many more games for significant results but the trend will likely not be different. Do I understand correctly Bert that your training games were played with the handcrafted Damage evaluation function? I used two batches, the firs...

Re: New draughts tournament

For your information the new version has a similar evaluation as Scan and Kingsrow. So based upon the principles Fabien invented, and shared within the community. Ed helped me a lot, as he provided me the proper tools. So I really feel im standing on the shoulders of 2 giants.... It would be more a...

I am trying to run hub 2.1 with scan 3.1 but so far have been unsuccessful. Hub throws a CreateProcess error when it tries to run scan. Has anyone successfully run this combination on Windows?
I have no trouble running hub 2.1 with scan 3.1 on Windows 7.

Re: Programmer poll: TCEC-like competition for draughts engines

Bert, that would be great. I think we can start with a few engines and a test tournament. Then hopefully more programmers will follow into the 21st century.
It also depends on how long Krzysztof is prepared to play tournaments and matches manually.

Programmer poll: TCEC-like competition for draughts engines

Many of you may know the Top Chess Engine Championship (TCEC), see https://tcec-chess.com/ . This is a chess engine competition where the tournaments are fully automated and broadcast online, using an engine protocol such as Universal Chess Interface (UCI), see https://en.wikipedia.org/wiki/Universa...

Re: How to set the clock

Well, there is nothing wrong with that if you use an increment of 3 seconds and the game lasted 80 moves (5 minutes + 80 moves x 3 seconds = 9 minutes). The question is whether a program actually goes below 0:00. If you want the external clock to be leading and have the possibility that a program lo...

Re: Internet engine matches

But switching off pondering, and hence the search threads, alone does not solve it. There can also be memory conflicts because of the memory used by the two programs for the transposition table and endgame database; Windows will then start swapping memory blocks from RAM to- and from the disk. Are ...

Re: How to set the clock

Do you ask because, in the next tournament, you want to display times for the audience that are better approximations of the internal clocks of both programs? My estimate is that on average it takes about 3 seconds for an operator to play a move on the board and to press the clock. Just so I underst...
