New engine: Lizard

Post by liamt »

Hi all,

My name is Liam, and I'm from the US.
I've been working on a C# engine for a while now, and I think it is in a good enough place now to publicize it!
It requires .NET 8 to build, but the most recent releases were compiled using AOT and (hopefully) don't need any kind of .NET framework to run.

By default, it currently uses a neural network (768 -> 1024 -> 1) which I trained myself using a large Lc0 dataset. It can also use (for didactic purposes) Stockfish HalfKP and HalfKA_v2 neural networks, but this is disabled by default and requires rebuilding it specifically with that enabled.

From my own matches against CCRL engines, I think it will be somewhere around 3150.

The source code and Windows releases are available on GitHub: https://github.com/liamt19/Lizard

I have only tested it on my hardware, so if anyone runs into issues please let me know!

EDIT: I've renamed the engine from "LTChess" to "Lizard", and updated the post's title and link accordingly.
