std::optional< evaluator_fitness_t< E > > ultra::de::numerical_refinement_backend::operator() ( evaluator_individual_t< E > & ind, const E & eva, const parameters::refinement_parameters & params ) const

inline

Refines the tunable scalar parameters of ind.

Parameters

[in,out]	ind	individual whose scalar parameters are refined
[in]	eva	evaluator used to score candidate solutions
[in]	params	refinement configuration parameters

Returns

improved fitness if refinement succeeded; empty std::optional otherwise

The optimiser extracts a decision vector from ind, performs numerical optimisation over a bounded region around the current parameter values, and writes the best solution back into ind.

If ind exposes no optimisable parameters, this function has no effect.
