UserCutCallbackI

Class IloCplex::UserCutCallbackI

Definition file: ilcplex/ilocplexi.h

Note

This is an advanced class. Advanced classes 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 classes 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.
