I noticed that repeated calls of the member function setQuadCoef of the class IloObjective can be prohibitively slow.The Cplex 12.5 manual reveals that it creates the appropriate instance of the undocumented class IloChange to notify algorithms about this change of an extractable object in the model.Is there a faster way of constructing a sparse quadratic objective function?Can notifications to classes to as IloModel and IloCplex be suppressed during model setup and manually triggered afterwards?
Cplex C++ Interface: Repeated calls of setQuadCoef are slow. Is there an alternative?
