=Dynamic Improving=
[[Aron Petkovski]] introduced the concept of ''Dynamic Improving''. By using static evaluation differences as a bonus to a improving score, Dynamic Improving allows for more control over improving-based mechanisms.

SearchStackEntry *past_stack = nullptr;
if ((stack - 2)->static_eval != kScoreNone) {
past_stack = stack - 2;
} else if ((stack - 4)->static_eval != kScoreNone) {
past_stack = stack - 4;
}
if (past_stack) {
// Smoothen the improving rate from the static eval of our position in
// previous turns
const Score diff = stack->static_eval - past_stack->static_eval;
stack->improving_rate =
std::clamp(past_stack->improving_rate + diff / 50.0, -1.0, 1.0);
}
