Date: Sun Aug 16 21:10:26 2020 +0200 Timestamp: 1597605026 Assume network file is in little-endian byte order This patch fixes the byte order when reading 16- and 32-bit values from the network file on a big-endian machine. Bytes are ordered in read_le() using unsigned arithmetic, which doesn't need tricks to determine the endianness of the machine. Unfortunately the compiler doesn't seem to be able to optimise the ordering operation, but reading in the weights is not a time-critical operation and the extra time it takes should not be noticeable. Big endian systems are still untested with NNUE. fixes #3007 closes https://github.com/official-stockfish/Stockfish/pull/3009 No functional change. see source |

This patch will force Stockfish to use NNUE eval more and more in materially unbalanced positions, when it seems that the classical eval is struggling to win and only manages to shuffle. This will ask the (slower) NNUE eval to double-check the potential fortress branches of the search tree, but only when necessary. passed STC: https://tests.stockfishchess.org/tests/view/5f36f1bf11a9b1a1dbf192d8 LLR: 2.93 (-2.94,2.94) {-0.50,1.50} Total: 51824 W: 5836 L: 5653 D: 40335 Elo +1.23 Ptnml(0-2): 264, 4356, 16512, 4493, 287 passed LTC: https://tests.stockfishchess.org/tests/view/5f37836111a9b1a1dbf1936d LLR: 2.93 (-2.94,2.94) {0.25,1.75} Total: 29768 W: 1747 L: 1590 D: 26431 Elo +1.83 Ptnml(0-2): 33, 1347, 11977, 1484, 43 closes https://github.com/official-stockfish/Stockfish/pull/3011 Bench: 4173967 see source |
