Dev Builds » 20230122-0954

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Update UCI_Elo parameterization The old parameterization (https://github.com/official-stockfish/Stockfish/pull/2225/files) has now become quite inaccurate. This updates the formula based on updated results with master. The formula is based on a fit of the Elo results for games played between master at various skill levels, and various versions of the Stash engine, which have been ranked at CCRL. ``` # PLAYER : RATING ERROR POINTS PLAYED (%) 1 master-skill-19 : 3191.1 40.4 940.0 1707 55 2 master-skill-18 : 3170.3 39.3 1343.0 2519 53 3 master-skill-17 : 3141.3 37.8 2282.0 4422 52 4 master-skill-16 : 3111.2 37.1 2773.0 5423 51 5 master-skill-15 : 3069.5 37.2 2728.5 5386 51 6 master-skill-14 : 3024.8 36.1 2702.0 5339 51 7 master-skill-13 : 2972.9 35.4 2645.5 5263 50 8 master-skill-12 : 2923.1 35.0 2653.5 5165 51 9 master-skill-11 : 2855.5 33.6 2524.0 5081 50 10 master-skill-10 : 2788.3 32.0 2724.5 5511 49 11 stash-bot-v25.0 : 2744.0 31.5 1952.5 3840 51 12 master-skill-9 : 2702.8 30.5 2670.0 5018 53 13 master-skill-8 : 2596.2 28.5 2669.5 4975 54 14 stash-bot-v21.0 : 2561.2 30.0 1338.0 3366 40 15 master-skill-7 : 2499.5 28.5 1934.0 4178 46 16 stash-bot-v20.0 : 2452.6 27.7 1606.5 3378 48 17 stash-bot-v19.0 : 2425.3 26.7 1787.0 3365 53 18 master-skill-6 : 2363.2 26.4 2510.5 4379 57 19 stash-bot-v17.0 : 2280.7 25.4 2209.0 4378 50 20 master-skill-5 : 2203.7 25.3 2859.5 5422 53 21 stash-bot-v15.3 : 2200.0 25.4 1757.0 4383 40 22 stash-bot-v14 : 2145.9 25.5 2890.0 5167 56 23 stash-bot-v13 : 2042.7 25.8 2263.5 4363 52 24 stash-bot-v12 : 1963.4 25.8 1769.5 4210 42 25 master-skill-4 : 1922.9 25.9 2690.0 5399 50 26 stash-bot-v11 : 1873.0 26.3 2203.5 4335 51 27 stash-bot-v10 : 1783.8 27.8 2568.5 4301 60 28 master-skill-3 : 1742.3 27.8 1909.5 4439 43 29 master-skill-2 : 1608.4 29.4 2064.5 4389 47 30 stash-bot-v9 : 1582.6 30.2 2130.0 4230 50 31 master-skill-1 : 1467.6 31.3 2015.5 4244 47 32 stash-bot-v8 : 1452.8 31.5 1953.5 3780 52 33 master-skill-0 : 1320.1 32.9 651.5 2083 31 ``` Skill 0 .. 19, now covers CCRL Blitz Elo from 1320 to 3190, approximately. Indeed, the Elo of stash in this analysis is only to within +- 100 Elo of CCRL, probably because it depends quite a bit on the opponent pool. To obtain a skill level for a given Elo number, the above data is fit as a 3rd degree polynomial Skill(Elo). A quick test confirms the correspondence to the above table: ``` Score of master-elo-2721 vs stash-bot-v21.0: 51 - 16 - 19 [0.703] 86 Elo difference: 150.1 +/- 70.2, LOS: 100.0 %, DrawRatio: 22.1 % ``` closes https://github.com/official-stockfish/Stockfish/pull/4341 No functional change.
