Commit ID 08385527dd470ece814ac85013802995a0e7f6ca
Author Joost VandeVondele

Introduce a function to compute NNUE accumulator This patch introduces `hint_common_parent_position()` to signal that potentially several child nodes will require an NNUE eval. By populating explicitly the accumulator, these subsequent evaluations can be performed more efficiently. This was based on the observation that calculating the evaluation in an excluded move position yielded a significant Elo gain, even though the evaluation itself was already available (work by pb00067). Sopel wrote the code to perform just the accumulator update. This PR is based on cleaned up code that passed STC: https://tests.stockfishchess.org/tests/view/63f62f9be74a12625bcd4aa0 LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 110368 W: 29607 L: 29167 D: 51594 Ptnml(0-2): 41, 10551, 33572, 10967, 53 and in an the earlier (equivalent) version passed STC: https://tests.stockfishchess.org/tests/view/63f3c3fee74a12625bcce2a6 LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 47552 W: 12786 L: 12467 D: 22299 Ptnml(0-2): 120, 5107, 12997, 5438, 114 passed LTC: https://tests.stockfishchess.org/tests/view/63f45cc2e74a12625bccfa63 LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 110368 W: 29607 L: 29167 D: 51594 Ptnml(0-2): 41, 10551, 33572, 10967, 53 closes https://github.com/official-stockfish/Stockfish/pull/4402 Bench: 3726250
