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
dual() -> float[]

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

Return

(float[])

BoundInterfaceConstraint.index
index(int idx) -> Constraint
index(int[] idxa) -> Constraint

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
slice(int first, int last) -> Constraint
slice(int[] firsta, int[] lasta) -> Constraint

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)
