NLopt provides a common interface for many different optimization algorithms, including: Algorithms using function values nonlinear control optimization tool. However, reverting back to nlopt-2. 25 , triggered by Travis There are two errors: your definition of f has the wrong signature, and it should instead be f(x::Vector, grad::Vector), see for instance NLopt tutorial;; the algorithm MMA requires you to provide the gradient of the objective function. You should file an issue with JuMP. NLopt bindings for julia. jl is the Julia wrapper of NLopt. toml at master · JuliaOpt/NLopt. Alternatively, you can use import NLopt if you want to keep all the NLopt symbols in their Since JuMP generates the objective function for you, so you can't insert tracing if you want to, it seems like this should be a JuMP issue. Using the Julia API. opt(nlopt. Is there a snippet of code / example of throwing a CTRL-C exception that would gracefully halt an NLopt optimization in julia REPL? The conclusion of the monthly developer call is that we should close this issue because it is nearly 10 years old, and because it is a "feature" of the upstream library.
