I have a MIP in which I add cuts in a user callback (using JuMP 0.18.5, CPLEX 0.5, MathProgBase 0.7.7). I would like to retrieve the LP bound in the current node of the B&B tree, e.g., by doing something like
In the documentation of MathProgBase I only found
cbgetlpsolution which returns a vector of the current variable values, or
cbgetbestbound which returns the objective value of the best remaining node by calling
Did I miss something in the documentation? Do you have any other suggestions how to get the bound?
Thank you in advance, Michael
