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.

প্যারামিটার:

  • 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.
