I have an extremely hard NLP that I want to solve via @NLopt. I can get the code running but there is no output unless the algorithm gets terminated. Now I have two questions:
- Is it possible to extract the optimality gap from the Global Optimization solvers in this package?
-If no, then is it possible to at least see the iterations? (it seems that nlopt has a parameter called “verbose” that can control what to display in MATLAB but not in Julia?).
Thanks a lot.
