Optimization problems (`qiskit.optimization.problems`)¶

Quadratic program¶

Structures for defining an optimization problem.

Quadratically Constrained Quadratic Program representation.

Note

The following classes are not intended to be instantiated directly. Objects of these types are available within an instantiated QuadraticProgram.

`Constraint`	Abstract Constraint Class.
`LinearExpression`	Representation of a linear expression by its coefficients.
`LinearConstraint`	Representation of a linear constraint.
`QuadraticExpression`	Representation of a quadratic expression by its coefficients.
`QuadraticConstraint`	Representation of a quadratic constraint.
`QuadraticObjective`	Representation of quadratic objective function of the form: constant + linear * x + x * quadratic * x.
`QuadraticProgramElement`	Interface class for all objects that have a parent QuadraticProgram.
`Variable`	Representation of a variable.
