Chess engine: Midnight v9

 


Midnight - UCI Engines
Author: Archishmaan Peyyety  Rating CEDR=3321

File structure
  • ChessEngine contains the C++ chess engine. It produces moves in uci format.
  • ChessEngine/ChessEngine_lib contains the core library including move search and evaluation.
  • ChessEngine/ChessEngine_tests contains the unit tests to verify that function in the lib work as expected. 
  • uci-gui contains a python module that produces a chess gui that a human can play with and interfaces with the chess engine built. Hosted on localhost and built using flask. Most of this is code I took from [here](https://github.com/maksimKorzh/uci-gui). I take no credit for it, just something so that I can play against my engine!
