java.lang.Object ilog.cplex.IloCplex.Callback ilog.cplex.IloCplex.OptimizationCallback ilog.cplex.IloCplex.MIPInfoCallback ilog.cplex.IloCplex.FractionalCutInfoCallback
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.
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 |
protected IloCplex.FractionalCutInfoCallback()
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
FractionalCutInfoCallback
objects directly.
Method Detail |
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.
IloException
