Class IloCplex::CrossoverCallbackI

Definition file: ilcplex/ilocplexi.h

Map of IloCplex::CrossoverCallbackI

An instance of the class IloCplex::CrossoverCallbackI represents a user-written callback in an application that uses an instance of IloCplex to solve a problem by means of the barrier optimizer with the crossover option. An instance of IloCplex calls this callback regularly during crossover. For details about the crossover option, see the CPLEX User's Manual.

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.
