Chess engine: Midnight v7

on

 


Midnight - UCI Engines
Author: Archishmaan Peyyety  Rating CEDR=3030

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!

v.7:
This marks the 7th version of the Midnight Chess Engine. Development has slowed significantly as Midnight has gotten stronger and as I've gotten busier with other projects. This version of Midnight includes a major bug fix to Moves To Go time controls that should allow Midnight to perform with comparable strength to its shorter time control results. I expect Midnight v7 to be around ~3150 CCRL ELO.
