operations_research::LinearRange Class Reference

Detailed Description

An expression of the form:

lower_bound <= sum_{i in S} a_i*x_i <= upper_bound. 

The sum is represented as a LinearExpr with offset 0.

Must be added to model with

MPSolver::AddRowConstraint(const LinearRange& range,
                           const std::string& name);

Constructor & Destructor Documentation

LinearRange() [2/2]

operations_research::LinearRange::LinearRange	(	double	lower_bound,
		const LinearExpr &	linear_expr,
		double	upper_bound )

The bounds of the linear range are updated so that they include the offset from "linear_expr", i.e., we form the range:

lower_bound - offset <= linear_expr - offset <= upper_bound - offset.
