Hi! Can you compile new stockfish nnue to use polyglot books?

Download the network, rename to nn.bin. And specify the full path in the engine parameter. If everything is done correctly, then the score in the starting position will not be zero.

https://dropmefiles.com/Nm4MP - Video instruction

https://www.comp.nus.edu.sg/~sergio-v/nnue/ - Here are the nets

Be aware:
1- Stockfish nnue is not +80 elo points stronger than Stockfish, they are equal in strength, it's a hoax spread by chess.com
2- Stockfish nnue is unstable: I've tried it and I've lost several games because of suddendly bad moves from 0.00 to +1.84 or -2.53 (I used the latest Segio network).

This is not true there is a Discord, there are numerous tests. For a short time very even strong

Processor:Intel Core i5-7600K, GHz:4.20 , Threads:4, Gui:Fritz-11, Games:100, Time:10s+1s, Book:Goi_6.2.3_ctg (book only for the classic engine) ,Endgame tables:Syzygy 3-4-5, Hash:128 MB, Ponder:Off.

https://dropmefiles.com/dXj8v


Classic Stockfish loses even with a full-fledged strong book. Stockfish NUE played without a book. At night, I will do the test again, but I will allocate this book to both engines . Similar I already did ,only book 4 running was




https://dropmefiles.com/I3vIm

And there are a lot of similar tests in other people.invitation .

Can I have in other host? dropmefiles are blocked to me...

Write an email and I will send you the engine for Android

I communicate through a translator, I thought you needed on Android NNUE

why do you need a book polyglot for NNUE network from Sergio better plays. I have shown above that even the book of the Goi could not defeat the net. And the network goes out every day for several pieces. Stronger and stronger

I have no time to make this test at the moment because I have more important tasks to do, like stopping to lose on Playchess (none of them is using Stockfish nnue) but I'm pretty sure that if I do it I'll be the right one. I didn't see all this excitement for Stockfish nnue on Playchess; the most used engine is Eman Enigma.

Add NNUE evaluation …

Add NNUE evaluation

This patch ports the efficiently updatable neural network (NNUE) evaluation to Stockfish.

Both the NNUE and the classical evaluations are available, and can be used to
assign a value to a position that is later used in alpha-beta (PVS) search to find the
best move. The classical evaluation computes this value as a function of various chess
concepts, handcrafted by experts, tested and tuned using fishtest. The NNUE evaluation
computes this value with a neural network based on basic inputs. The network is optimized
and trained on the evalutions of millions of positions at moderate search depth.

The NNUE evaluation was first introduced in shogi, and ported to Stockfish afterward.
It can be evaluated efficiently on CPUs, and exploits the fact that only parts
of the neural network need to be updated after a typical chess move.
[The nodchip repository](https://github.com/nodchip/Stockfish) provides additional
tools to train and develop the NNUE networks.

This patch is the result of contributions of various authors, from various communities,
including: nodchip, ynasu87, yaneurao (initial port and NNUE authors), domschl, FireFather,
rqs, xXH4CKST3RXx, tttak, zz4032, joergoster, mstembera, nguyenpham, erbsenzaehler,
dorzechowski, and vondele.

This new evaluation needed various changes to fishtest and the corresponding infrastructure,
for which tomtor, ppigazzini, noobpwnftw, daylen, and vondele are gratefully acknowledged.

The first networks have been provided by gekkehenker and sergiovieri, with the latter
net (nn-97f742aaefcd.nnue) being the current default.

The evaluation function can be selected at run time with the `Use NNUE` (true/false) UCI option,
provided the `EvalFile` option points the the network file (depending on the GUI, with full path).

The performance of the NNUE evaluation relative to the classical evaluation depends somewhat on
the hardware, and is expected to improve quickly, but is currently on > 80 Elo on fishtest:

60000 @ 10+0.1 th 1
https://tests.stockfishchess.org/tes...abc164f05e4c4c
ELO: 92.77 +-2.1 (95%) LOS: 100.0%
Total: 60000 W: 24193 L: 8543 D: 27264 Elo +92.77
Ptnml(0-2): 609, 3850, 9708, 10948, 4885

40000 @ 20+0.2 th 8
https://tests.stockfishchess.org/tes...abc164f05e4c58
ELO: 89.47 +-2.0 (95%) LOS: 100.0%

Ptnml(0-2): 74, 1583, 8550, 7776, 2017

At the same time, the impact on the classical evaluation remains minimal, causing no significant
regression:

sprt @ 10+0.1 th 1
https://tests.stockfishchess.org/tes...abc164f05e4c5b
LLR: 2.94 (-2.94,2.94) {-6.00,-4.00}
Total: 34936 W: 6502 L: 6825 D: 21609 Elo -3.21
Ptnml(0-2): 571, 4082, 8434, 3861, 520

sprt @ 60+0.6 th 1
https://tests.stockfishchess.org/tes...abc164f05e4c5d
LLR: 2.93 (-2.94,2.94) {-6.00,-4.00}
Total: 10088 W: 1232 L: 1265 D: 7591 Elo -1.14
Ptnml(0-2): 49, 914, 3170, 843, 68

The needed networks can be found at https://tests.stockfishchess.org/nns
It is recommended to use the default one as indicated by the `EvalFile` UCI option.

Guidelines for testing new nets can be found at
https://github.com/glinscott/fishtes...nnue-net-tests

Integration has been discussed in various issues:
https://github.com/official-stockfis...sh/issues/2823
https://github.com/official-stockfis...sh/issues/2728

The integration branch will be closed after the merge:
https://github.com/official-stockfis...fish/pull/2825
https://github.com/official-stockfis...nue-player-wip

closes https://github.com/official-stockfis...fish/pull/2912

This will be an exciting time for computer chess, looking forward to seeing the evolution of
this approach.

Maybe I am doing something wrong but for me this engine is terrible without book.
