Concept definition

template<typename Domain>
concept Aleph::GameEvaluator =  requires(Domain &domain, const typename Domain::State &state) {
  typename Domain::Score;
  requires AdversarialScore<typename Domain::Score>;
  { domain.is_terminal(state) } -> std::convertible_to<bool>;
  { domain.evaluate(state) } -> std::convertible_to<typename Domain::Score>;
}

Detailed Description

Required evaluator contract for zero-sum games.

evaluate(state) must return a score from the perspective of the player to move in state. This is the key convention that keeps Negamax and Alpha-Beta compact and symmetric.
