CCRL Discussion Board

Thanks Gabor, I have mentioned 1400 ELO, but I can see on the CCRL Blitz list that the ELO scores are lower than they was a couple of months ago - at least for the weaker engines. Based on many games against the engines Ozwald, Phalp and Quokka, I estimate CederChess 2 to have an ELO in the 1250 ra...

Hi everyone, thank you for the tests! I updated, the readme of the project with the latest results. Two days ago, I released the new Velvet v7.0.0: https://github.com/mhonert/velvet-chess/releases/tag/v7.0.0 The estimated strength increase is around 65 Elo. Additional details can be found in the re...

Hej Gabor (or another admin), Did you see my request for CederChess 2 ? My guess is that is about 200 ELO stronger than CederChess 1. Best regards, Claus Hi Claus, I don't remember to have seen it, maybe somehow I missed it but it can be that I saw it but forgot. I'm going to test it as soon as I h...

I am not a statistician, and don't have an opinion why. Its perhaps the number of games that is important. I am not one either. But to use only one opponent against each of the engines may cause distortions. That's why we test each engine against a wide selection of engines. Also, we try to select ...

Which are they?

Hello, I am looking for binaries to test my engine. I could find some directly on github, but not all. Some home sites are even dead. So, is there somewhere a repositery with binaries that testers use ? Thanks Philippe Hi Philippe, These links may help you: http://computer-chess.org/doku.php?id=com...

Using Process Explorer I can see that it uses only one thread while searching. I could not stop searching by issuing 'stop', it must be done some other way I guess. I’m slightly puzzled by this. When I run the engine from the command window on my PC, I can use ‘go depth 100’ or ‘go infinite’. When ...

Will that extra thread occupy a core constantly? I would not like it because it slows my machine down. Interface and search are running in separate threads, so two threads are used for running the engine. When running the search the usage of CPU goes to full use, but when the search stops, the usag...

A new version of Lambergar engine was released, fixing bug 1 and 3 mentioned in previous posts. New version is available on https://github.com/jabolcni/Lambergar/releases/tag/v0.4.1 Just downloaded it. Its test will be delayed by a couple of days because of my limited resorces. Will that extra thre...

Thanks, I see you already did that.

I have started a tournament with version 2.0.1. I'm just watching the first game and I'm a bit worried because memory usage is constantly growing, now it's at 1210 MB at move 40. At move 60 it is 1520. Maximum value, when the game ended at move 80, was 1566 if my eyes did not deceive me. I can toler...

I fixed that issue, it now correctly identifies itself as "Lunarr": https://github.com/Eliagiac/lunarr-chess-engine/releases/tag/v2.0.1 White Widow was what I originally called the project, but it was pretty random and didn't really have any meaning. Recently I decided to dedicate it to m...

Thank you, I updated the release to include various dependencies in the .exe file. I think it should work fine now: https://github.com/Eliagiac/lunarr-chess-engine/releases/tag/v2.0.0 Uhh, it's huge! But it moves. Only, it displays its name as White Widow. To be honest, I like that name much more. ...

And a new patch has been put out https://github.com/eboatwright/Maxwell/releases/tag/v3.0.8-2 Although if you have to add this as separate version, you an probably just skip it, because I think v3.1 might be out soon :D Thank you! I will skip it. And I suggest you take your time with the next versi...

I have found this three: [Event "Maxwell 3.0.8-1 64-bit - Jan 15"] [Site "Szentendre"] [Date "2024.01.18"] [Round "23"] [White "Maxwell 3.0.8-1 64-bit"] [Black "Skiull 0.5 64-bit"] [Result "0-1"] [ECO "B40"] [Opening &qu...

Oh, I have just noticed your post. What you have provided here is enough. You may announce future versions here. An alternative is TalkChess. Also, I'm going to visit your site and follow you there. Although my schedule is crowded I'm going to try to test your engine before long. EDIT: It does not m...

Hi Janez, I have observed odd things. 1. Run from the command line memory usage is 243 MB with default settings. Issuing 'setoption name Hash value 256' the amount is 4 times of that, 1145 MB. Process Explorer says those are private bytes, while Working Set is 154 MB and 524 MB, respectively. 2. Run...

Noted.

Thanks for testing Maxwell! It's really cool to see my little engine up there on the listings, I'm still hard at work on v3.1: I've been rewriting the whole search function to be more centered around a Principal Variation Search, whereas before it was more focused on Late Move Reductions A further ...

Just out of curiosity, would you have an estimate of when v2.0 will be tested for an approximate rating/elo? I can only speak for myself, not for other testers. I can't see myself testing v2.0 in the near future, in fact ever. Let me quote what I once wrote to another author: I myself also allow NN...

Just noticed this. Started a gauntlet. Most likely will not appear in this week's blitz list, only next week.

Hi, I hope you're doing well, I'm just wondering if there's an update for the evaluation of my engine. I'm especially curious for the rating of v2.0, and wondering if this version could be listed? Understanding the ongoing evaluations for numerous engines, I appreciate your team's efforts and will ...

OK, I've started a gauntlet with 3.0.8-1 and we'll see what future brings.

In that case I'd rather wait for that release and not test 3.0.8.
