Constructor & Destructor Documentation

libstp::autotune::control::DifferentialEvolution::DifferentialEvolution	(	IDifferentialEvolutionRating &	rating,
		int	numParams,
		bool	dither = false,
		std::uint32_t	seed = 0xC0FFEEu )

Parameters

rating	cost function (minimised).
numParams	problem dimensionality.
dither	enable per-step random weighting factor.
seed	PRNG seed (defaults to a fixed value for reproducibility).
