Let me know if you think Lunarr would be competitive in my Division 10 field. It would be amazing to participate in the tournament. However, even with these last few updates, Lunarr has an Elo rating somewhere between 2000 and 2050, whereas the other engines competing seem to be in the 2200-2400 ra...

I found a major bug when detecting draws by repetition. It is now fixed in the latest release: https://github.com/Eliagiac/lunarr-chess-engine/releases/tag/v2.1.1 All information about positions reached before the root was lost when copying the board with the previous implementation, causing the eng...

The hash table size can be configured to any amount of memory, using "setoption name Hash value x". The default value is 64 MB. I was referring to the overall memory usage of the program, which previously increased indefinitely as the game went on because it was storing recerences to unnec...

I just published a new release addressing the memory issues: https://github.com/Eliagiac/lunarr-chess-engine/releases/tag/v2.1.0 It now uses about 400-600 MB while playing, much better compared to the 1 GB+ of before. Previously, the engine was keeping track of all the nodes in the search tree at al...

BTW, I have .NET 3 and .NET 7 installed. I developed the engine using .NET 8, so it needs the latest libraries to work properly. 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, w...

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 my...

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-ches ... tag/v2.0.0

Hi everyone, For the past couple of years, I've been working on a UCI chess engine written in C#, and I believe it's now stable enough to compete with other engines. It is free and open-source. The code and releases can be found here: https://github.com/Eliagiac/lunarr-chess-engine. It's a personal ...
