Constructor & Destructor Documentation

nltool::Box::Box

(

)

Non-consistent constructor

nltool::Box::Box	(	const stdVector &	l,
		const stdVector &	u
	)

Creates a box represented by lower and upper bounds

Parameters:

l	a vector corresponding to the lower bounds
u	a vector corresponding to the upper bounds

nltool::Box::Box	(	unsigned	dim,
		const Vertices &	vertices
	)

Creates the minimal box representation which contains a vertices list

Parameters:

dim	the set dimension
vertices	a list of vertices

nltool::Box::Box	(	unsigned	dim,
		const Template &	A,
		const Vector &	b
	)

Creates a box that approximates a set of constraints given by the inequalities A*x<=b

Parameters:

dim	the set dimension
A	a matrix representing the left part of the inequalities
b	a vector representing the right part of the inequalities

nltool::Box::Box

Returns:

maximal lenghts

Number nltool::Box::getMinInterval

(

)

Returns the minimal lenght of the box

Returns:

minimal lenghts

bool nltool::Box::include

(

Hpolyhedron &

poly

)

Inclusion test with poluhedron

Parameters:

poly	a polyhedron represented by a set of constraints

Returns:

is poly included in this box?

Number nltool::Box::optimize	(	const Vector &	direction,
		Vector &	optPoint,
		bool	max = true
	)		[virtual]

Performs a quick linear optimisation in this box

Parameters:

direction	optimization
optPoint	the problem solution
max	is a maximization problem (otherwise minimization)

Returns:

optimization result

Reimplemented from nltool::Set.
