Enclosing class:

IloCplex

public abstract static class IloCplex.DisjunctiveCutInfoCallback
extends IloCplex.MIPInfoCallback

Monitors the progress of the generation of disjunctive cuts when a mixed integer programming problem (MIP) is being solved.

An instance of the class DisjunctiveCutInfoCallback 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 allows you to monitor the progress of the generation of disjunctive cuts.

User-written callbacks of this class are compatible with dynamic search.

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.

The user-written callback of this class is called by only one thread, even in the case of parallel execution. Consequently, it is not necessary for the user-written callback to manage synchronization.

Constructor Detail

IloCplex.DisjunctiveCutInfoCallback

protected IloCplex.DisjunctiveCutInfoCallback()

Constructor for user-written disjunctive cut callbacks.

This constructor can be called only to construct objects of derived user-written callback classes, but not to construct DisjunctiveCallback objects directly.

Method Detail

getProgress

protected double getProgress()
                      throws IloException

Returns the fraction of completion of the disjunctive cut generation.

The returned values are in the range of 0.0 to 1.0.

Throws:

IloException

Returns:

The fraction of completion of the disjunctive cut generation.
