public abstract static class IloCplex.FlowMIRCutCallback

extends IloCplex.MIPCallback

An instance of the class FlowMIRCutCallback represents a user-written callback in an application that uses an instance of IloCplex to solve a mixed integer programming problem (a MIP). This class offers a method to monitor the progress of the generation of flow cover and mixed integer rounding (MIR) cuts.

The constructor and methods of this class are protected to make sure that they are used only to derive a user-written callback class or to implement the main method in it. This is the callback class to use when IloCplex is solving a MIP.

Constructor Detail

IloCplex.FlowMIRCutCallback

protected IloCplex.FlowMIRCutCallback()

Constructor for user-written flow cover and MIR cut callbacks. This constructor can be called only to construct objects of derived user-written callback classes, but not to construct IloCplex.FlowMIRCutCallback objects directly.

Method Detail

getProgress

protected double getProgress()
                      throws IloException

Returns the fraction of completion of the cut generation. The returned values are in the range of 0.0 to 1.0.

Returns:

The fraction of completion of the cut generation.

IloException
