This patch broadens and simplifies definition of PvNode that is likely to fail low. New definition can be described as following "If node was already researched at depth >= current depth and failed low there" which is more logical than the previous version and takes less space + allows to not recompute it every time during move loop.

This PR adds an ability to export any currently loaded network. The export_net command now takes an optional filename parameter. If the loaded net is not the embedded net the filename parameter is required. Two changes were required to support this: * the "architecture" string, which is really just a some kind of description in the net, is now saved into netDescription on load and correctly saved on export. * the AffineTransform scrambles weights for some architectures and sparsifies them, such that retrieving the index is hard. This is solved by having a temporary scrambled<->unscrambled index lookup table when loading the network, and the actual index is saved for each individual weight that makes it to canSaturate16. This increases the size of the canSaturate16 entries by 6 bytes. closes official-stockfish#3456 No functional change

This patch increases lmrDepth threshold for continuation history based pruning in search.

After recent simplification of special conditions that sometimes increase it from 4 to 5 it was logical to overall test at longer time controls if 5 is better than 4 with deeper searches. reduces strenght on STC https://tests.stockfishchess.org/tests/view/60a3a8bbce8ea25a3ef03c74 ELO: -2.57 +-2.0 (95%) LOS: 0.6% Total: 20000 W: 1820 L: 1968 D: 16212 Ptnml(0-2): 68, 1582, 6836, 1458, 56 Passed LTC with STC bounds https://tests.stockfishchess.org/tests/view/60a027395085663412d090ce LLR: 2.93 (-2.94,2.94) <-0.50,2.50> Total: 175256 W: 6774 L: 6548 D: 161934 Ptnml(0-2): 91, 5808, 75604, 6034, 91 Passed VLTC with LTC bounds https://tests.stockfishchess.org/tests/view/60a2bccce229097940a037a7 LLR: 2.96 (-2.94,2.94) <0.50,3.50> Total: 65736 W: 1224 L: 1092 D: 63420 Ptnml(0-2): 5, 1012, 30706, 1136, 9 closes official-stockfish#3473 bench 3689330

The Tempo variable was introduced 10 years ago in our search because the
classical evaluation function was antisymmetrical in White and Black by design
to gain speed:
Eval(White to play) = -Eval(Black to play)
Nowadays our neural networks know which side is to play in a position when
they evaluate a position and are trained on real games, so the neural network
encodes the advantage of moving as an output of search. This patch shows that
the Tempo variable is not necessary anymore.

Note: there are two locations left in search.cpp where we assume antisymmetry
of evaluation (in relation with a speed optimization for null moves in lines
770 and 1439), but as the values are just used for heuristic pruning this
approximation should not hurt too much because the order of magnitude is still
true most of the time.

This simplification patch implements two changes: 1. it simplifies away the so-called "lazy" path in the NNUE evaluation internals, where we trusted the psqt head alone to avoid the costly "positional" head in some cases; 2. it raises a little bit the NNUEThreshold1 in evaluate.cpp (from 682 to 800), which increases the limit where we switched from NNUE eval to Classical eval. Both effects increase the number of positional evaluations done by our new net architecture, but the results of our tests below seem to indicate that the loss of speed will be compensated by the gain of eval quality.

Do you think pretending those other accounts aren't yours does anything? Why do you think github keeps banning your alt accounts? Do you really think pretending to talk to yourself fools anyone? |

It is not fruitful at all to harass all those wonderful developers that
bring us the best chess engine in the world, Stockfish. If you feel you are
smarter than them, create your own project, your very own chess engine.
Then we could return the favor and harass you back. I’m sure you’ll be
extremely delighted by this.

Please stop. You can’t have everything in life, especially not by brute
force. Also, you can’t force other people to do what you want to see or
have in their own creation. If you want anything in life, to be truly
yours, make it yourself. So, stop with this bullshit and make your own
chess engine. That way, you’ll have total and complete control over how
exactly will your very own chess engine behave. Thank you. I hope you find
peace soon.

Intrusive people can’t have everything in life, simply because the sheer
intrusiveness repels the experience of everything. That is the law of the
universe.

@BehindTheEyes may I ask you why did you tag me in the comment? What do I have to do with this? |

I already said that Stockfish 15.1 found Qe4 on depth 30 with default parameters. Why we are talking about that? |

On March 22, 2023, the Kingdom of North Barchant hosted its inaugural online chess tournament at lichess.org. The tournament was a success, attracting many new users, and we plan to continue hosting regular tournaments in the future. To increase participation, we will pay for advertising and encourage people to register at lichess. We would like to request permission to use our own flag, in addition to the pirate or any other flag. The Kingdom of North Barchant is a micronation, and our citizens would be proud to display the flag of their state during the tournament. We appreciate your consideration and thank you for your support. |

@Matthies You are owner of @RubiChess. Why you sent a report to Github for yourself ?!!! 😊😊😊 Good Luck |

Thank you for the organization but I don't need it and so I deleted it. |
those are trolls randomly pinging people |
|
nowadays the SF community seems to be a target for those trolls to get attention or to get some message out or just to connect subjects which are not related, etc. etc. .. i have no clue, it's ridiculous .. don't give them attention, at all. |
