Add new range constraints to a model. A range constraint states that the value of the input expression must be between the specified lower and upper bounds in any solution.

GRBConstr[] AddRanges ( GRBLinExpr[] exprs,
    double[] lower,
    double[] upper,
    string[] names )


exprs: Linear expressions for the new range constraints.

lower: Lower bounds for linear expressions.

upper: Upper bounds for linear expressions.

name: Names for new range constraints.

count: Number of range constraints to add.

Return value:

Array of new constraint objects.
