Function Documentation

optimise()

template<Evaluator E>
requires NumericalOptimisable<evaluator_individual_t<E>>

std::optional< evaluator_fitness_t< E > > ultra::de::optimise	(	const refiner &	opt,
		evaluator_individual_t< E > &	ind,
		const E &	eva )

Convenience API for DE-based numerical refinement.

Parameters

[in]	opt	refiner coordinating the refinement process
[in,out]	ind	individual whose scalar parameters are refined
[in]	eva	evaluator used to score candidate solutions

Returns

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

Refines the tunable scalar parameters of ind using Differential Evolution through opt.
