Chess engine: DanaSah 9.0 and NNUE

-

Danasah - UCI chess engine
Author - Pedro Castro, Rating CEDR=3084 (24.04.2022)

DanaSah - a Chess Engine Communication Protocol, and since version 6.1 UCI compatible open source chess engine under the GNU General Public License 3 by Pedro Castro, written in C, and first released in January 2005. Also, since DanaSah 6.1 in May 2016, Chess960 is supported, available as Windows, Linux and Android binary. DanaSah 8.8, released in April 2021, supports Stockfish compatible NNUE networks. source


 Changed:
The engine can read NNUE-type neural networks. This gives a lot of strength.
The search has many changed parameters, but the strength with the classic evaluation is the same as the previous version.
There are changes to the limited strength version (although it is not included here).

Other minor changes.
dananet1.nnue --> This is the default network used by 8.8 version, it has been trained with 340 million positions with ccrl 40/2 games (learn by result) and then with 340 millon positions in depth 5 generated with the first net.
dananet2.nnue --> This is the default network used by 9.0 version, it has been trained with 340 millon positions in depth 9 generated with dananet1.

DanaSah 9.0 64-bit Elo CCRL 40/15 --> 3190
DanaSah 8.8 64-bit Elo CCRL 40/15 --> 3143

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
