Detailed Description

Provides a DE-specific interface to the generic problem class.

The class is a facade that provides a simpler interface to represent DE-specific problems.

Examples: rastrigin.cc.

Constructor & Destructor Documentation

◆ de_problem() [1/2]

vita::de_problem::de_problem	(	std::size_t	parameters,
		const range_t< double > &	range
	)

Sets up a DE problem for which a solution has the given number of (uniform, same range) parameters.

Parameters

[in]	parameters	number of parameters (aka genes in the chromosome)
[in]	range	a half-open interval (the value of each parameter falls within this range)

The typical solution of a numerical optimization problem can often be represented as a sequence of real numbers in a given range (and this is the raison d'etre of this constructor).

Definition at line 70 of file ga/problem.cc.

◆ de_problem() [2/2]

vita::de_problem::de_problem ( const std::vector< range_t< double > > & ranges )

explicit

Sets up a DE problem for which a solution has the given number of (uniform but not same range) parameters.

Parameters

[in] ranges a sequence of half-open intervals (one for each parameter)

This is a more flexible form of the other constructor. Each parameter has its own range.
