Document Elo impact of various parts of search In order to understand better the impact of various techniques used in search, Elo estimates have been run at STC for 60000 games (statistical error ~1.8 Elo), disabling each feature in turn. This should help future improvements and simplifications to pick suitable targets. The list of tests is: step 7 : http://tests.stockfishchess.org/tests/view/5abcbb4b0ebc5902926cf1ca step 8 : http://tests.stockfishchess.org/tests/view/5abcbb680ebc5902926cf1cc step 9 : http://tests.stockfishchess.org/tests/view/5abcbb850ebc5902926cf1ce step 10 : http://tests.stockfishchess.org/tests/view/5abcbbeb0ebc5902926cf1d2 step 11 : http://tests.stockfishchess.org/tests/view/5abcbbbf0ebc5902926cf1d0 step 13 : http://tests.stockfishchess.org/tests/view/5abd03680ebc5902926cf20b step 13a: http://tests.stockfishchess.org/tests/view/5abd29660ebc5902926cf22a step 13b: http://tests.stockfishchess.org/tests/view/5abd29820ebc5902926cf22c step 14 : http://tests.stockfishchess.org/tests/view/5abd03860ebc5902926cf20f step 14a: http://tests.stockfishchess.org/tests/view/5abd2b6c0ebc5902926cf230 step 14b: http://tests.stockfishchess.org/tests/view/5abd2b8d0ebc5902926cf232 step 14c: http://tests.stockfishchess.org/tests/view/5abd2bad0ebc5902926cf234 step 14d: http://tests.stockfishchess.org/tests/view/5abd2bcf0ebc5902926cf236 step 14e: http://tests.stockfishchess.org/tests/view/5abd2bf10ebc5902926cf238 This patch documents this in the code. Note that it will be a waste to recompute these estimates often, even a couple of [0,5] patches are unlikely to change them by more than the error bars. The interest of the Elo annotations in the code is not in the details, but in high- lighting trends such as razoring (2 Elo) and singular extensions (60 Elo). These estimates should be recomputed at most once a year. Closes https://github.com/official-stockfish/Stockfish/pull/1522 No functional change.
