QuadraticConstraint¶
-
class
QuadraticConstraint(quadratic_program, name, linear, quadratic, sense, rhs)[source]¶ Bases:
qiskit.optimization.problems.constraint.ConstraintRepresentation 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 (
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.
Methods
Evaluate the left-hand-side of the constraint.
