Class IloCplex.FractionalCutCallback
java.lang.Object
ilog.cplex.IloCplex.Callback
ilog.cplex.IloCplex.MIPCallback
ilog.cplex.IloCplex.FractionalCutCallback
- All Implemented Interfaces:
- java.lang.Cloneable
- Enclosing class:
- IloCplex
- public abstract static class IloCplex.FractionalCutCallback
- extends IloCplex.MIPCallback
This is the callback class to use to monitor the progress
of the generation of fractional cuts when a mixed integer
programming problem (MIP) is being solved.
An instance of this class represents a user-written callback in an
application that uses an instance of IloCplex
to solve a
mixed integer programming problem (a MIP). It allows you to
monitor the progress of the generation of fractional 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.

IloCplex.FractionalCutCallback
protected IloCplex.FractionalCutCallback()
- Constructor for user-written fractional cut callbacks.
This constructor can be called only to construct objects of
derived user-written callback classes, but not to construct
IloCplex.FractionalCutCallback
objects directly.

protected double getProgress()
throws IloException
- Returns the fraction of completion of the fractional cut generation.
The returned values are in the range of 0.0 to 1.0.
- Returns:
- The fraction of completion of the fractional cut generation.
- Throws:
IloException
