Note:This is an advanced routine. Advanced routines typically demand a profound
understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher
risk of incorrect behavior in your application, behavior that can be difficult to
debug. Therefore, ILOG encourages you to consider carefully whether you can
accomplish the same task by means of other Callable Library routines instead.
An instance of the class IloCplex::UserCutCallbackI represents a user-written
callback in an application that uses an instance of IloCplex to solve a MIP while
generating user cuts to tighten the LP relaxation. IloCplex calls the user-written
callback after solving each node LP exactly like IloCplex::CutCallbackI. It
differs from IloCplex::CutCallbackI only in that constraints added in a
UserCutCallbackI must be real cuts in the sense that omitting them does not affect
the feasible region of the model under consideration.
