An instance of the class
IloCplex::FractionalCutInfoCallbackI
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 check on
the progress of the generation of fractional cuts.
User-written callbacks of this class are compatible with MIP dynamic search.
The constructor and methods of this class are protected for use
in deriving a user-written callback class and in implementing the
main
method there.
If an attempt is made to access information not available to an instance of this class, an exception is thrown.
