Great to hear. Two minor questions which aren't clear (to me) from the documentation: - Once a user defined function has been defined and registered, can it be incorporated into NL expressions via @defNLExpr? - The documentation references both ForwardDiff.jl and ReverseDiffSparse.jl. Which is used where? What are the tradeoffs users should be aware of?
Semi-unrelated: two days ago I was using JuMP 0.12 and NLopt to solve what should have been a very simple (2 variable) nonlinear problem. When I fed the optimal solution as the starting values for the variables, the solve(model) command (or NLopt) hung indefinitely. Perturbing my starting point by .0001 fixed that - solve returned a solution instantaneously-by-human-perception. Am I doing something dumb?
