Chess book: Cerebellum_light 170525

BrainFish  - UCI chess engine Information from the author: Brainfish  is a standard  Stockfish  chess engine extended by a general book format that is capable of handling a reduced part of Cerebellum, which is an innovative chess opening and playing book. In  Brainfish , the book moves are only used in engine games, not in analysis mode. All moves in the published book  Cerebellum_light.bin  generated by Cerebellum were calculated by using Stockfish as analysis engine, without using statistics. Then those moves where recalulated by the Cerebellum Library using a graph algorithm that makes all scores in the library consistant. Consistant scores means for example, in case the starting position has a score of 0.2 and a best move is 1.e4, the position after 1.e4 must have the score -0.2. Additionally, some others properties are found, like the best main line of a position and possible Transitions. Hence, when  Brainfish  is playing moves that are in the Cerebellum book, it

Isa 2.0.45 - winboard chess engine (Windows and Linux)

Image
Isa  - winboard chess engine About engine:  Isa  is a chess engine I developp during my free time. Chess programming is my hobby since the 80's years. I started developing with QuickBasic 4.5 (I wrote a weak engine named Bishop) . Then I learned the C langage and studed the TSCP source code (like everyone I think) . « Titan » and « DCP » (DCP = Titan + winboard protocol) was born . Strengh was always so weak , around 1400 elo . After that I rewrote again my engine and Jars came out (I released Jars) and then Yoda (both played around 1800-1900 elo. After finding dificult to improve , I stopped working on both engines and started to work on Isa , a diferent way. I started Isa from Firstchess.c source.
