QuadraticConstraint#

class QuadraticConstraint(quadratic_program, name, linear, quadratic, sense, rhs)[source]#

Bases: Constraint

Representation of a quadratic constraint.

Constructs a quadratic constraint, consisting of a linear and a quadratic term.

Parameters:

  • quadratic_program (Any) – The parent quadratic program.

  • name (str) – The name of the constraint.

  • linear (ndarray | spmatrix | List[float] | Dict[int | str, float]) – The coefficients specifying the linear part of the constraint.

  • quadratic (ndarray | spmatrix | List[List[float]] | Dict[Tuple[int | str, int | str], float]) – The coefficients specifying the linear part of the constraint.

  • sense (ConstraintSense) – The sense of the constraint.

  • rhs (float) – The right-hand-side of the constraint.

Attributes

quadratic_program#

Returns the parent QuadraticProgram.

Returns:

The parent QuadraticProgram.

rhs#

Returns the right-hand-side of the constraint.

Returns:

Methods

evaluate(x)[source]#

Evaluate the left-hand-side of the constraint.

Parameters:

x (ndarray | List | Dict[int | str, float]) – The values of the variables to be evaluated.

Returns:

The left-hand-side of the constraint given the variable values.

Return type:

float
