If we use the "side to move" of the entry instead of the template, one of the classify methods goes away. Furthermore, I've resolved the colors in some of the statements (we're already assuming direction using NORTH), and used stm (side to move) instead of "us," since this is much clearer to me. This is not tested because it is non-functional, only applies building the bitbase and there are no changes to the binary (on my machine).

Date: Sat Jan 18 01:44:37 2020 +0100 Timestamp: 1579308277 Stockfish 11 Official release version of Stockfish 11. Bench: 5156767 ----------------------- It is our pleasure to release Stockfish 11 to our fans and supporters. Downloads are freely available at http://stockfishchess.org/download/ This version 11 of Stockfish is 50 Elo stronger than the last version, and 150 Elo stronger than the version which famously lost a match to AlphaZero two years ago. This makes Stockfish the strongest chess engine running on your smartphone or normal desktop PC, and we estimate that on a modern four cores CPU, Stockfish 11 could give 1:1000 time odds to the human chess champion having classical time control, and be on par with him. More specific data, including nice cumulative curves for the progression of Stockfish strength over the last seven years, can be found on [our progression page][1], at [Stefan Pohl site][2] or at [NextChessMove][3]. In October 2019 Stockfish has regained its crown in the TCEC competition, beating in the superfinal of season 16 an evolution of the neural-network engine Leela that had won the previous season. This clash of style between an alpha-beta and an neural-network engine produced spectacular chess as always, with Stockfish [emerging victorious this time][0]. Compared to Stockfish 10, we have made hundreds of improvements to the [codebase][4], from the evaluation function (improvements in king attacks, middlegame/endgame transitions, and many more) to the search algorithm (some innovative coordination methods for the searching threads, better pruning of unsound tactical lines, etc), and fixed a couple of bugs en passant. Our testing framework [Fishtest][5] has also seen its share of improvements to continue propelling Stockfish forward. Along with a lot of small enhancements, Fishtest has switched to new SPRT bounds to increase the chance of catching Elo gainers, along with a new testing book and the use of pentanomial statistics to be more resource-efficient. Overall the Stockfish project is an example of open-source at its best, as its buzzing community of programmers sharing ideas and daily reviewing their colleagues' patches proves to be an ideal form to develop innovative ideas for chess programming, while the mathematical accuracy of the testing framework allows us an unparalleled level of quality control for each patch we put in the engine. If you wish, you too can help our ongoing efforts to keep improving it, just [get involved][6] :-) Stockfish is also special in that every chess fan, even if not a programmer, [can easily help][7] the team to improve the engine by connecting their PC to Fishtest and let it play some games in the background to test new patches. Individual contributions vary from 1 to 32 cores, but this year Bojun Guo made it a little bit special by plugging a whole data center during the whole year: it was a vertiginous experience to see Fishtest spikes with 17466 cores connected playing [25600 games/minute][8]. Thanks Guo!

The idea is that the next iteration will generally take about the same amount of time as has already been used in total. When we are likely to begin the last iteration, as judged by total time taken so far > 0.6 * optimum time, searching the last depth again instead of increasing the depth still helps the other threads in lazy SMP and prepares better move ordering for the next moves.

Date: Fri Jan 10 03:31:44 2020 +0100 Timestamp: 1578623504 Update Elo estimates for terms in search This updates estimates from 1.5 year ago, and adds missing terms. All estimates from tests run on fishtest at 10+0.1 (STC), 20000 games, error bars +- 3 Elo, see the original message in the pull request for the full list of tests. Noteworthy changes are step 7 (futility pruning) going from ~30 to ~50 Elo and step 13 (pruning at shallow depth) going from ~170 to ~200 Elo. Full list of tests: https://github.com/official-stockfish/Stockfish/pull/2401 @Rocky640 made the suggestion to look at time control dependence of these terms. I picked two large terms (early futility pruning and singular extension), so with small relative error. It turns out it is actually quite interesting (see figure 1). Contrary to my expectation, the Elo gain for early futility pruning is pretty time control sensitive, while singular extension gain is not. Figure 1: TC dependence of two search terms  Going back to the old measurement of futility pruning (30 Elo vs today 50 Elo), the code is actually identical but the margins have changed. It seems like a nice example of how connected terms in search really are, i.e. the value of early futility pruning increased significantly due to changes elsewhere in search.

Date: Thu Jan 9 19:48:47 2020 +0100 Timestamp: 1578595727 50-moves rule improvement for transposition table User "adentong" reported recently of a game where Stockfish blundered a game in a tournament because during a search there was an hash-table issue for positions inside the tree very close to the 50-moves draw rule. This is part of a problem which is commonly referred to as the Graph History Interaction (GHI), and is difficult to solve in computer chess because storing the 50-moves counter in the hash-table loses Elo in general. Links: Issue 2451 : https://github.com/official-stockfish/Stockfish/issues/2451 About the GHI : https://www.chessprogramming.org/Graph_History_Interaction This patch tries to address the issue in this particular game and similar reported games: it prevents that values from the transposition table are getting used when the 50-move counter is close to reaching 100 (). The idea is that in such cases values from previous searches, with a much lower 50-move count, become less and less reliable. More precisely, the heuristic we use in this patch is that we don't take the transposition table cutoff when we have reached a 45-moves limit, but let the search continue doing its job. There is a possible slowdown involved, but it will also help to find either a draw when it thought to be losing, or a way to avoid the draw by 50-move rule. This heuristics probably will not fix all possible cases, but seems to be working reasonably well in practice while not losing too much Elo.

Date: Tue Jan 7 11:00:54 2020 +0100 Timestamp: 1578391254 Use a faster implementation of Static Exchange Evaluation SEE (Static Exchange Evaluation) is a critical component, so we might indulge some tricks to make it faster. Another pull request #2469 showed some speedup by removing templates, this version uses Ronald de Man (@syzygy1) SEE implementation which also unrolls the for loop by suppressing the min_attacker() helper function and exits as soon as the last swap is conclusive. See Ronald de Man version there: https://github.com/syzygy1/Cfish/blob/master/src/position.c Patch testes against pull request #2469: LLR: 2.95 (-2.94,2.94) {-1.00,3.00} Total: 19365 W: 3771 L: 3634 D: 11960 Elo +2.46 Ptnml(0-2): 241, 1984, 5099, 2092, 255 http://tests.stockfishchess.org/tests/view/5e10eb135e5436dd91b27ba3 And since we are using new SPRT statistics, and that both pull requests finished with less than 20000 games I also tested against master as a speed-up: LLR: 2.99 (-2.94,2.94) {-1.00,3.00} Total: 18878 W: 3674 L: 3539 D: 11665 Elo +2.48 Ptnml(0-2): 193, 1999, 4966, 2019, 250 http://tests.stockfishchess.org/tests/view/5e10febf12ef906c8b388745 Non functional change see source |
