This idea was given by Vizvezdenec: https://tests.stockfishchess.org/tests/view/65f0a2360ec64f0526c46752. The PvNode extension margin was also adjusted from 50 to 40. This tune also differs from previous tuning attempts by tuning the evaluation thresholds for smallnet and psqt-only. The former was increased through the tuning, and this is hypothesized to scale better at VVLTC, although there is not much evidence of it.

Date: Wed Mar 20 16:29:35 2024 +0100 Timestamp: 1710948575 Base WDL model on material count and normalize evals dynamically This PR proposes to change the parameter dependence of Stockfish's internal WDL model from full move counter to material count. In addition it ensures that an evaluation of 100 centipawns always corresponds to a 50% win probability at fishtest LTC, whereas for master this holds only at move number 32. See also https://github.com/official-stockfish/Stockfish/pull/4920 and the discussion therein. The new model was fitted based on about 340M positions extracted from 5.6M fishtest LTC games from the last three weeks, involving SF versions from e67cc979fd2c0e66dfc2b2f2daa0117458cfc462 (SF 16.1) to current master. The involved commands are for [WDL_model](https://github.com/official-stockfish/WDL_model) are: ``` ./updateWDL.sh --firstrev e67cc979fd2c0e66dfc2b2f2daa0117458cfc462 python scoreWDL.py updateWDL.json --plot save --pgnName update_material.png --momType "material" --momTarget 58 --materialMin 10 --modelFitting optimizeProbability ``` The anchor `58` for the material count value was chosen to be as close as possible to the observed average material count of fishtest LTC games at move 32 (`43`), while not changing the value of `NormalizeToPawnValue` compared to the move-based WDL model by more than 1. The patch only affects the displayed cp and wdl values. closes https://github.com/official-stockfish/Stockfish/pull/5121 No functional change see source |

Date: Tue Mar 12 16:41:08 2024 +0100 Timestamp: 1710258068 Refactor Network Usage Continuing from PR #4968, this update improves how Stockfish handles network usage, making it easier to manage and modify networks in the future. With the introduction of a dedicated Network class, creating networks has become straightforward. See uci.cpp: ```cpp NN::NetworkBig({EvalFileDefaultNameBig, "None", ""}, NN::embeddedNNUEBig) ``` The new `Network` encapsulates all network-related logic, significantly reducing the complexity previously required to support multiple network types, such as the distinction between small and big networks #4915.

The reasoning is that these values are used in both `evaluate.cpp` and `evaluate_nnue.cpp`, and thus unifying their usage avoids inconsistencies during testing, where one occurrence is changed without the other (this happened during the search tune SPRT). closes https://github.com/official-stockfish/Stockfish/pull/5101 Bench: 1741218 see source |
