Quadratic program#

Structures for defining an optimization problem.

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.
