14.2.3 Class BoundInterfaceConstraint

mosek::fusion::BoundInterfaceConstraint

Interface to either the upper bound or the lower bound of a ranged constraint.

This class is never explicitly instantiated; is is created by a RangedConstraint to allow accessing a bound value and the dual variable value corresponding to the relevant bound as a separate object. The constraint

\[b_l \leq a^T x \leq b_u\]

has two bounds and two dual variables; these are not immediately available through the RangedConstraint object, but can be accessed through a BoundInterfaceConstraint.

Implements

SliceConstraint

Members

BoundInterfaceConstraint.dual – Get the dual solution values of the constraint.

BoundInterfaceConstraint.index – Get a single element from a one-dimensional constraint.

BoundInterfaceConstraint.slice – Create a slice constraint.

Constraint.getModel – Return the model that the constraint belongs to.

Constraint.getND – Return the number of dimensions in the constraint shape.

Constraint.getShape – Return the constraint’s shape.

Constraint.getSize – Return the total number of elements in the constraint.

Constraint.level – Get the primal solution values of the constraint.

Constraint.remove – Remove the constraint from the model.

Constraint.update – Update part of a constraint.

SliceConstraint.toString – Create a human readable string representation of the constraint.

BoundInterfaceConstraint.dual

shared_ptr<ndarray<double,1>> dual()

Get the dual solution value of the constraint as an array.

Return

(double[])

BoundInterfaceConstraint.index

Constraint::t index(int idx)
Constraint::t index(shared_ptr<ndarray<int,1>> idxa)

Get a single element from a one-dimensional constraint.

Parameters

• idx (int) – The element index.

• idxa (int[]) – Array of integer coordinates in each dimension.

Return

(Constraint)

BoundInterfaceConstraint.slice

Constraint::t slice(int first, int last)
Constraint::t slice(shared_ptr<ndarray<int,1>> firsta, shared_ptr<ndarray<int,1>> lasta)

Create a slice constraint.

Parameters

• first (int) – Index of the first element in the slice.

• last (int) – Index of the first element after the end of the slice.

• firsta (int[]) – The indexes of first elements in the slice along each dimension.

• lasta (int[]) – The indexes of first elements after the end of the slice along each dimension.

Return

(Constraint)
