class Constraint(quadratic_program, name, sense, rhs)

Abstract Constraint Class.

Initializes the constraint.

Parameters

• quadratic_program (Any) – The parent QuadraticProgram.

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

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

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

__init__(quadratic_program, name, sense, rhs)

Initializes the constraint.

Parameters

• quadratic_program (Any) – The parent QuadraticProgram.

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

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

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

Methods

__init__(quadratic_program, name, sense, rhs)	Initializes the constraint.
evaluate(x)	Evaluate left-hand-side of constraint for given values of variables.

Attributes

name	Returns the name of the constraint.
quadratic_program	Returns the parent QuadraticProgram.
rhs	Returns the right-hand-side of the constraint.
sense	Returns the sense of the constraint.

Sense

alias of ConstraintSense
