qiskit.optimization.problems.LinearConstraint¶

class LinearConstraint(quadratic_program, name, linear, sense, rhs)[source]¶

Representation of a linear constraint.

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

__init__(quadratic_program, name, linear, sense, rhs)[source]¶

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

Methods

__init__(quadratic_program, name, linear, …)

Evaluate the left-hand-side of the constraint.

Attributes

`linear`	Returns the linear expression corresponding to the left-hand-side of the constraint.
`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 qiskit.optimization.problems.constraint.ConstraintSense

evaluate(x)[source]¶
