Chess engine: Bread Engine 0.0.10

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.0.0.10:
Added support for the 50 move rule, implemented late move reductions on the root node (~15 elo), disabled some transpositions cutoffs in the principal variation (~15 elo) and added reverse futility pruning (~35 elo). Bread Engine 0.0.10 is around 65 elo stronger than version 0.0.9.
