class QuadraticConstraint(quadratic_program, name, linear, quadratic, sense, rhs)

Representation of a quadratic constraint.

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

Parâmetros

• quadratic_program (Any) – The parent quadratic program.

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

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

• quadratic (Union[ndarray, spmatrix, List[List[float]], Dict[Tuple[Union[int, str], Union[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.
