Since you’re here...

... we have a small favour to ask. More people, like you, are reading and supporting our blog: "Chess Engines Diary". And unlike many other sites and blogs, we made the choice to keep our articles open for all, regardless of where they live or what they can afford to pay.

We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

Stockfish , chess engine UCI Rating JCER = 3331 🔬 Author: Joost VandeVondele More: Timestamp: 1503734014  Improve multi-threaded mate finding  If any thread found a 'mate in x' stop the search. Previously only  mainThread would do so. Requires the bestThread selection to be  adjusted to always prefer mate scores, even if the search depth is less.  I've tried to collect some data for this patch. On 30 cores, mate finding  seems 5-30% faster on average. It is not so easy to get numbers for this,  as the time to find a mate fluctuates significantly with multi-threaded runs,  so it is an average over 100 searches for the same position. Furthermore,  hash size and position make a difference as well.  Bench: 5965302  ⭐⭐⭐   Stockfish 17082609_ VandeVondele  - download

Chess Engine: BrainFish 170820 and book: Cerebellum Light 170819

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 plays li
