UCI_Elo implementation (#2225) This exploits the recent fractional Skill Level, and is a result from some discussion in #2221 and the older #758. Basically, if UCI_LimitStrength is set, it will internally convert UCI_Elo to a matching fractional Skill Level. The Elo estimate is based on games at TC 60+0.6, Hash 64Mb, 8moves_v3.pgn, rated with Ordo, anchored to goldfish1.13 (CCRL 40/4 ~2000). Note that this is mostly about internal consistency, the anchoring to CCRL is a bit weak, e.g. within this tournament, goldfish and sungorus only have a 200Elo difference, their rating difference on CCRL is 300Elo. I propose that we continue to expose 'Skill Level' as an UCI option, for backwards compatibility. The result of a tournament under those conditions are given by the following table, where the player name reflects the UCI_Elo. # PLAYER : RATING ERROR POINTS PLAYED (%) CFS(%) 1 Elo2837 : 2792.2 50.8 536.5 711 75 100 2 Elo2745 : 2739.0 49.0 487.5 711 69 100 3 Elo2654 : 2666.4 49.2 418.0 711 59 100 4 Elo2562 : 2604.5 38.5 894.5 1383 65 100 5 Elo2471 : 2515.2 38.1 651.5 924 71 100 6 Elo2380 : 2365.9 35.4 478.5 924 52 100 7 Elo2289 : 2290.0 28.0 864.0 1596 54 100 8 sungorus1.4 : 2204.9 27.8 680.5 1596 43 60 9 Elo2197 : 2201.1 30.1 523.5 924 57 100 10 Elo2106 : 2103.8 24.5 730.5 1428 51 100 11 Elo2014 : 2030.5 30.3 377.5 756 50 98 12 goldfish1.13 : 2000.0 ---- 511.0 1428 36 100 13 Elo1923 : 1928.5 30.9 641.5 1260 51 100 14 Elo1831 : 1829.0 42.1 370.5 756 49 100 15 Elo1740 : 1738.3 42.9 277.5 756 37 100 16 Elo1649 : 1625.0 42.1 525.5 1260 42 100 17 Elo1558 : 1521.5 49.9 298.0 756 39 100 18 Elo1467 : 1471.3 51.3 246.5 756 33 100 19 Elo1375 : 1407.1 51.9 183.0 756 24 --- It can be observed that all set Elos correspond within the error bars with the observed Ordo rating.
