Tune search constants This is the result of a 200k tuning run at LTC: http://tests.stockfishchess.org/tests/view/5d3576b70ebc5925cf0e9e1e which passed quickly at LTC: LLR: 2.95 (-2.94,2.94) [0.50,4.50] Total: 12954 W: 2280 L: 2074 D: 8600 http://tests.stockfishchess.org/tests/view/5d3ff3f70ebc5925cf0f87a2 STC failed, but second LTC at [0,4] passed easily: LLR: 2.96 (-2.94,2.94) [0.00,4.00] Total: 8004 W: 1432 L: 1252 D: 5320 http://tests.stockfishchess.org/tests/view/5d407cff0ebc5925cf0f9119 Further work? No doubt some of these changes produce most of the gain and some are neutral or even bad, so further testing on individual/groups of parameters changed here might show more gains. It does look like these tests might need to be at LTC though, so maybe not too practical to do.
