Chess engine: Clarity 5.1.0

-


Clarity
The C++ rewrite is complete! Clarity is now faster and better, using new techniques, and I have learned a new language!
For those who didn't see the engine in its depressing, confusing, error-filled C# state, this engine was originally written in C# before I decided to switch to C++. That decision was one of the greatest I think I've ever had, as the engine is now faster, easier to read, less error-filled(hopefully), and better overall.

Rating CEDR=3461

v.5.1.0:
I know it hasn't been that long, but Clarity is back once again! This time fixing issue #46, where under occasional and very specific (and impossible to replicate) circumstances, Clarity would play a null move. This has since been fixed 3 separate ways!

This version should be fine now though, 20000 games have been played with the fixes implemented so far and no illegal moves have happened, but if another one does happen feel free to make an issue here on this repo and I'll attempt to fix it as fast as possible.

How to choose what binary to use:
Each binary here is separated by the features that your CPU has, v1 has a simple popcnt instruction, but I'm not sure about v2, and v3 is divided into bmi2 and magic bitboard builds (if you have a Ryzen 3000 series CPU, go for the v3_magic), and v4 has everything.

If you are unsure about what features your CPU has, start from v4 and attempt to run it, if it doesn't run, move one lower, and keep doing that until a build runs. If none of them run, open an issue and I'll attempt to help.

New chess opening book: M11.2 (bin and ctg)

-
Image
  We provide two opening books, in two different formats: bin and ctg. This is enough to be used in almost any chess program (GUI). Of course, every book may contain errors, but this one is based on a high rating. Happy testing! Book - CTG format Customers who wish to use the CTG format book will need a GUI capable of reading this format, ie. Chessbase GUIs.  Please save the book in your book folder. We strongly recommend that you "Optimize" the book in the Book options dialog so the tournament moves are chosen. The book is very wide even in tournament mode unlike most other books. A type of book format mainly used by chess programs from Chessbase , such as Fritz, Chess Base, Komodo, FatFritz, Houdini , etc. Book - BIN format (  Used by chess GUIs Arena, Banksia and Droidfish) Binary books have some important advantages, especially for computer chess engines: space-efficient, fast on accessing and searching, more useful information.  At the most simple form, they are just a

New version chess engine: Lc0 BT4

-
Image
LcZero - CEDR Rating=3683 vBT4: Big transformer 4. New network architecture which builds off of BT3 by adding two types of auxiliary heads, future heads and categorical value heads. The categorical value heads predict a distribution over values of q rather than a WDL outcome distribution, and the future heads predict the moves that will be played over the next two plies. The hope is that these heads will give additional information to the net to improve training speed. We've also fixed half-precision training, so this model will be larger. BT4 training started in mid-October and is expected to take a few months. It has 15 layers with 1024 embedding size, 32 heads per layer, and 1536 emb size, for roughly a doubling in size over BT3.  Individual statistics:  Lc0 0.30.0 Stockfish 16 5/13 -3 13 Games Booot 7.2 6/10 +2 10 Games Critter 1.6a 8/9 +7 9 Games Dragon 3.2 4/8 +0 8 Games Stockfish 20230729 3.5/8 -1 8 Games ShashChess 33.2 3.5/8 -1 8 Games Fisherov chess monk 1.2 3/

Dragon NNUE by Komodo Chess - it's free!

-
Image
    Dragon by Komodo Chess Larry Kaufman: We have released Dragon at komodochess.com. Dragon uses NNUE (Neural Network Updated Efficiently) technology, originally developed for the game of shogi. Komodo has a great deal of chess knowledge in its evaluation. Training an NNUE network based on this evaluation was both an advantage and a challenge, requiring experimentation with architectures and data generation of billions of positions. The reinforcement learning phase for Dragon is in its infancy, but is already showing great promise. Dragon is a huge strength improvement over 14.1, the last release, about 197 elo in MCTS mode and 189 elo in standard mode, at CCRL blitz time control on one thread based on direct matches. With four threads, the gains were 156 elo in MCTS and 170 in standard mode. The improvement is due to the embedded neural network providing much more accurate evaluation and also in some sense gaining an extra ply or so of search by “seeing” some tactics that a normal ev
