Introduce simple_eval() for lazy evaluations This patch implements the pure materialistic evaluation called simple_eval() to gain a speed-up during Stockfish search. We use the so-called lazy evaluation trick: replace the accurate but slow NNUE network evaluation by the super-fast simple_eval() if the position seems to be already won (high material advantage). To guard against some of the most obvious blunders introduced by this idea, this patch uses the following features which will raise the lazy evaluation threshold in some situations: - avoid lazy evals on shuffling branches in the search tree - avoid lazy evals if the position at root already has a material imbalance - avoid lazy evals if the search value at root is already winning/losing. Moreover, we add a small random noise to the simple_eval() term. This idea (stochastic mobility in the minimax tree) was worth about 200 Elo in the pure simple_eval() player on Lichess. Overall, the current implementation in this patch evaluates about 2% of the leaves in the search tree lazily. -------------------------------------------- STC: LLR: 2.94 (-2.94,2.94) <0.00,2.00> Total: 60352 W: 15585 L: 15234 D: 29533 Ptnml(0-2): 216, 6906, 15578, 7263, 213 https://tests.stockfishchess.org/tests/view/64f1d9bcbd9967ffae366209 LTC: LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 35106 W: 8990 L: 8678 D: 17438 Ptnml(0-2): 14, 3668, 9887, 3960, 24 https://tests.stockfishchess.org/tests/view/64f25204f5b0c54e3f04c0e7 verification run at VLTC: LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 74362 W: 19088 L: 18716 D: 36558 Ptnml(0-2): 6, 7226, 22348, 7592, 9 https://tests.stockfishchess.org/tests/view/64f2ecdbf5b0c54e3f04d3ae All three tests above were run with adjudication off, we also verified that there was no regression on matetracker (thanks Disservin!). ---------------------------------------------- closes https://github.com/official-stockfish/Stockfish/pull/4771 Bench: 1393714
