Re: Gigabyte X399 AORUS Gaming 7

Hi Krzysztof, This is a very big problem, X399 motherboards are not available anymore, maybe you can get one from China, there seem to be some sellers there, but because these motherboards are scarce they ask premium prices for it. I only found a single advertisement in our local marketplace from so...

Re: Scan - new version

For draughts engines it seems to be common practice to enter the size of the transposition-table in powers of 2, either being it in bytes or entries. I think Scan does this in entries of 16 bytes each. When you enter 24 (the default it seems) the total size would be 2^24 x 16 = 268.435.456 bytes or ...

Re: INTERNATIONAL DRAUGHTS ENGINES BLITZ 2022

Hi Sidiki, Thank you for organizing this tournament. I understand it's a lot of work to play all these games by hand, and to keep track of what the programs are doing without making a mistake. As you already know, I'm working on the next version of Ares, that will be better and hopefully stronger, s...

Hi Sidiki,

I was wondering what happened, sorry to hear that you are not recovered yet. Hopefully you will get well very soon.

Hi Sidiki,

What is going on? Is this 'blitz' tournament still running or not?

Re: INTERNATIONAL DRAUGHTS ENGINES BLITZ 2022

Hi Sidiki, Thank you for the information! I assume you have to play the games by hand and that you are very busy with it. It would be easier to automate these tournaments by building a special site for it, e.g. something like lidraughts.org, this would be a lot of work though, it probably isn't wort...

Re: INTERNATIONAL DRAUGHTS ENGINES BLITZ 2022

Hi Sidiki, Good luck with the tournament! Can you tell what kind of hardware do you use for this tournament? Processor, clock frequency, number of threads and memory size? I assume you use two computers to allow the engines to ponder, are these computers hardware wise exactly the same or are they di...

Re: Internet engine matches

Hi Krzysztof,

There is a new Ares version 1.53d on the FTP-server. In my tests it is about 4 Elo stronger than the previous version. The N/s went down somewhat, this is because it enters the quiescence search less frequently, and not because the engine is slower.

Re: INTERNATIONAL DRAUGHTS ENGINES BLITZ 2022

Hi Sidiki, I tried to mail you, somehow it doesn't work, my mail-server doesn't want to send out mail to you. Maybe the problem is on my end, I don't know, I will take a look at it today. Today or tomorrow I will put the new version 1.53d on the FTP-server, in single core tests it improved about 4 E...

Re: Internet engine matches

Krzysztof, In the mean time I made a small change that makes the engine somewhat better at tactics. I'm testing it right now, when it is really better according to my tests, I will bump the version to 1.53d and send you the new version. I'm also working on a simple GUI (Windows only) to make the en...

Re: Internet engine matches

The win (and only win in this match) of Ares in game 123 is a little strange. The move from KR 43. 20-15 was definitely wrong and losing, whereas 43. 28-22 27x18 44. 42-37 41x43 45. 49x38 is a draw. I expect that with 16-cores KR would not have search problems. Ed, can you give some light, is this ...

Re: NNUE

Another possibility I'm thinking about is to use small overlapped patterns e.g. 3 bits or 5 bits and combining the indices by means of a NN. With one-hot encoding you will get a huge number of inputs, but with NNUE this is not a big problem. The incremental update will be slower because for most squ...
