Sugar-NN1.1 32-64 Empty SugaR-NN_2019-08-13

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.

SugaR: Updated November, 6 2019.

- Changelog: Changelog: SugaR-NN updated to November 4, 2019, in particular: changes.

This version is quite impressive in speed:

Sugar-NN1.1 32-64 Snn061119depth

this was reached in the ending phase of a game. I hope such speed doesn't come with the price of avoiding some important branch... Anyway, tried today the x64 (not bmi2) version, I was amazed how it made draw in a disadvantaged position against Exxon.

Game:
[White "Exxon, NazFish 051119 64 B"]
[Black "Maxath, SugaR-NN 061119 64"]
[Result "1/2-1/2"]
[WhiteElo "2546"]
[BlackElo "2472"]
[EventDate "2019.11.06"]
1.a3 e5 2.c4 Nc6 3.e3 Nge7 4.b4 d5 5.cxd5 Nxd5 6.Qc2 Bd6 7.Bb2 f5 8.Nf3 Qe7 9.d3 a5 10.b5 Nd8 11.g3 Bd7 12.Nc3 Nxc3 13.Qxc3 Nf7 14.d4 e4 15.Ne5 Bxe5 16.dxe5 Be6 17.Be2 O-O 18.Rc1 Rfc8 19.Qc5 Qe8 20.h4 Nd8 21.O-O b6 22.

Yes, I know that the opening 1.a3 is very weak, but there was a moment in which the Black (myself) was in disadvantage and I thought I had lost the game... SugaR instead recovered and lead to a draw.
