BrainFish - UCI chess engine JCER Rating=3378 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

Stockfish , chess engine UCI Rating JCER = 3389 🔬 Author: Joost VandeVondele  Timestamp: 1513611141  Allow for general transposition table sizes. (#1341)  For efficiency reasons current master only allows for transposition table sizes that are N = 2^k in size, the index computation can be done efficiently as (hash % N) can be written instead as (hash & 2^k - 1). On a typical computer (with 4, 8... etc Gb of RAM), this implies roughly half the RAM is left unused in analysis.  Recently a neat trick was proposed to map a hash into the range [0,N[ more efficiently than (hash % N) for general N, nearly as efficiently as (hash % 2^k):  namely computing (hash * N / 2^32) for 32 bit hashes. This patch implements this trick and now allows for general hash sizes. Note that for N = 2^k this just amounts to using a different subset of bits from the hash. Master will use the lower k bits, this trick will use the upper k bits (of the 32 bit hash).  LLR: 2.96 (-2.94,2.94) [-3.00

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.
