I understand your position. Example nonlinearly constrained problem. It is necessary to install the NLOpt library. jl to compute automatic derivatives. . In this tutorial, we illustrate the usage of NLopt in various languages via one or two trivial examples. py in the main folder can be used instead of Lumopt's optimization. He's also tried std::numeric_limits::max(), but NLOPT then takes that ridiculous number literally and it screws up the derivative estimates.
