Stockfish compile under a different name !
He does not know anything about programming
Maybe only he can double-click on the "BYO" file to make every day a new Stockfish compile !? lol

Sugar and a derived and was released with the source code in compliance with the GPL
Please members staff modify the THREAD
Why do you continue to allow this user (tyuyy) to write a lot of filth?

The latest version of Sugar complies with the GPL, so the title of this thread is now misleading.

Hi Graham
Not latest version, all builds have attached the source code and can be downloaded
I stopped immediately collaboration with Yaroslav Venhrynovych

Ok, I have quickly checked the sources.

It is Stockfish from a couple of weeks ago + syzgy tablebases + lage pages

The only difference I found in the actual code is a little change in the way qsearch is called in PV nodes, namely qsearch recurses in a PV node only for the first move, all the others are called with NonPV parameter.

There is also some code to print UCI hashfull info.

That's all. I have found no other differences.

SugaR: Updated August, 13 2019 .

After the latest surprising great performances (a tester of mine tried SugaR against Raubfisch, with a surprising result of Sugar doubling the wins), I couldn't avoid to host this engine on my website, but before I had to put my hand on it since I don't like all those files created in the same place where the chess engine is. So now they are all into a folder called 'SugaR-NN Files', a much more orderly way.

- Changelog: this distribution is an adaptation of SugaR-NN dated Jul 31, 2019, I have set the program to put any output file into the created directory 'SugaR-NN Files'.

SugaR is a free UCI chess engine derived from Stockfish made by Marco Zerbinati under the GPL license.

This version of SugaR supports up to 128 cores; the engine can use two parallel BIN books (original code by Thomas Zipproth) and has a Self Learning function implemented.

NN section (Experimental Neural Networks inspired techniques)

Experimental, MonteCarloTreeSearch, if activated, the engine's behaviour is similar to AlphaZero concepts.

Idea are implemented, integrated on SugaR:

NN Persisted Self-Learning

Boolean, Default: True

(Montecarlo by Kelly Kinyama) only when true. This creates three files for machine learning purposes: SugaR-NN implements a persistent learning algorithm by Kelly kyniama and Andrea Manzo. Reads and creates the following file types: pawngame.bin with the learning when there are max a total of 2 pieces for white and black

experience.bin with the learning for
- opening variation of max 16 moves (8 half-moves) and a total of at least 7 pieces (no pawns) for white and black
- positions with max 6 pieces (no pawns) for white and black

One or many .bin files, each one associated to a single position biunivocally associated to the (technically, hashKey), in an opening variation of max 8 moves (16 half-moves) and a total of at least 7 pieces (no pawns) for white and black. This position is also in the experience.bin. So, these files are to speed the load in memory.

Every .bin file is so a collection of one or more positions stored with the following format (similar to in memory Stockfish Transposition Table):

- best move
- board signature (hash key)
- best move depth
- best move score

At the engine loading, there is an automatic merge to pawn.bin and experience.bin files, if we put the other ones, based on the following convention:

.bin

where
- fileType="experience"/"bin"
- qualityIndex , an integer, incrementally from 0 on based on the file's quality assigned by the user (0 best quality and so on)

The opening files can be simply copied and, in case of conflict/same name, the user must choice the one to use.

Because of disk access, to be effective, the learning must be made at no bullet time controls (less than 5 minutes/game).

NN Perceptron Algorithm

Boolean, Default: False
(Perceptron Sigmoid activation by Stefano Cardanobile) for Late Move Reductions search as training signal

NN MCTS Score

Boolean, Default: False
((Montecarlo Tree Search Scores) by Jörg Oster) in main search function to an upper node.
