Difference between GRBcblazy and GRBaddconstr

[Guido Pantuza - Miziphi]

Dear, I implemented a MIP using CallBack function. For distraction, I used, inside the callback function, to insert the violated constraint, the  GRBadconstr instead of GRBcblazy.

In practice, what difference between using one or the other?

To Use the GRBadconstr can provoke an error? Which?

You should only call the GRBcbcut (see http://www.gurobi.com/documentation/6.5/refman/c_grbcbcut.html) or GRBcblazy (see http://www.gurobi.com/documentation/6.5/refman/c_grbcblazy.html) functions within a callback. Please follow the links to read about when you should use them.
