UCI chess engines: Devre
Author: Ömer Faruk Tutkun Rating CEDR=3373
Devre is an open-source UCI compatible chess engine written in C as a hobby project.The code is a bit badly written now but I'll try to make it cleaner and more efficent in my free time. Although Devre is an original chess engine written from scratch, I got great help from chessprogramming wiki , talkchess forum,stcokfish discord ,and some open-source C engines: Ethereal, Vice, CPW.
