Tuned Values after 2 million spsa games Various king and pawn eval values tuned after 2 million games. Rounding slightly adjusted. LTC: http://tests.stockfishchess.org/tests/view/5b477a260ebc5978f4be3ed4 LLR: 2.95 (-2.94,2.94) [0.00,4.00] Total: 32783 W: 5852 L: 5588 D: 21343 STC: http://tests.stockfishchess.org/tests/view/5b472d420ebc5978f4be3e4d LLR: 3.23 (-2.94,2.94) [0.00,4.00] Total: 44380 W: 10201 L: 9841 D: 24338 I think I reached the limit of the fishtest framework. It frequently crashed at 2 million games already. The small values also moved a lot throughout the entire tuning session though with smaller margin. The passed danger and close enemies values seems the most sensitive (changing close enemies alone to 6 failed before but now it passes), whether or not they are close to optimal I don't know, but it seems some parameters are also correlated to others.
