Concept definition

template<class T>
concept ultra::Strategy = 
  requires
  {
    typename std::remove_cvref_t<T>::evaluator_type;
  }
  && Evaluator<typename std::remove_cvref_t<T>::evaluator_type>
  && std::derived_from<
       std::remove_cvref_t<T>,
       evolution_strategy<typename std::remove_cvref_t<T>::evaluator_type>>

Detailed Description

Concept identifying valid compile-time evolutionary strategies.

A type satisfies Strategy if, after removing cv/ref qualifiers:

• it exposes an evaluator_type;
• that type satisfies Evaluator;
• the type derives from evolution_strategy<evaluator_type>.

This allows the concept to recognise both evolution_strategy<E> itself and concrete strategy classes derived from it, such as alps_es<E>, std_es<E>, and de_es<E>.
