Detailed Description

A collection of constraints, implemented as a vector.

Is used to define the constraints for all variables used during an optimization session.

Constructor & Destructor Documentation

Initializes a collection of constraints with default values. All constraints are of type real and have the same default min and max.

Parameters:

Initializes a collection of constraints from string descsriptions. Currently used only for range based constraints.

A constraint can be described as "type;min;max" where type can be real or integer and min and max are the range limits.

Parameters:

str	a a collection (vector) of constraint description strings, each string describing constraints for one variable
var_count	the total number of variables (can be different than the number of strings). If there are more variables than strings, the extra constraints are set to be real and use the default min and max arguments for the range
def_min	default min value in case the number of variables is higher than the number of constraints specified as strings.
def_max	default max value in case the number of variables is higher than the number of constraints specified as strings.

double de::constraints::get_rand_value ( size_t index ) [inline]

returns a random value limited to the type and range of the constraint

double de::constraints::get_rand_value	(	size_t	index,
		double	value,
		double	origin
	)		`[inline]`

returns a random value limited to the type and range of the constraint based on a previous value and an origin

Parameters:

DVectorPtr de::constraints::get_rand_values ( ) const [inline]

Get a set of random values within the limits set by the constraints

DVectorPtr de::constraints::get_square_zone_rand_values	(	const DVectorPtr	origin,
		double	sidePct
	)		const `[inline]`

Generates a set of random values within a "hypercube" region defined by an origin and an area expressed as a percentage of the entire range

Parameters:

origin	the origin coordinates of the region
sidePct	the side of the hypercube in pct of the entire side
