Futility pruning simplification 1/ eval margin and gains removed: 16bit are now free on TT entries, due to the removal of eval margin. may be useful in the future :) gains removed: use instead by Value(128). search() and qsearch() are now consistent in this regard. 2/ futility_margin() linear formula instead of complex (log(depth), movecount) formula. 3/ unify pre & post futility pruning pre futility pruning used depth < 7 plies, while post futility pruning used depth < 4 plies. Now it's always depth < 7. Tested with fixed number of games both at short TC: ELO: 0.82 +-2.1 (95%) LOS: 77.3% Total: 40000 W: 7939 L: 7845 D: 24216 And long TC ELO: 0.59 +-2.0 (95%) LOS: 71.9% Total: 40000 W: 6876 L: 6808 D: 26316 bench 7243575
