Chess engine: Bread Engine 1.0.0

on

 

Bread Engine is a chess engine written in c++. I started working on it in 2021, and only just finished. There is still a lot of room for improvement, but the engine is quite strong (for humans, at least). It uses NNUE (efficiently updatable neural network) to evaluate positions, as well as minimax search.

Bread engine does not have a GUI built in, however it supports the uci protocol, you can therefore run it on any chess GUI.

Improved UCI commands, neural network is now always embedded in the executable. Bread engine is now a single executable, that you can download and run directly.

v.1.0.0:
Bread Engine has been updated to version 1.0.0!

The patch version numbers were starting to get large... From now on, I will try to follow semantic versioning.

Bread engine 1.0.0 features null move pruning which makes it around 25 elo stronger than version 0.0.10 in short time controls, and around 55 elo stronger in long time controls.
