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. Package to call the NLopt nonlinear-optimization library from the Julia language - JuliaOpt/NLopt. The algorithm parameter is required, and all others are optional. It looks like this is a bug in JuMP. This software solves nonlinear control problems at a high-level very quickly. jl, you can build arbitrarily complex objective and constraint functions using these differentiable functions as building blocks or lego pieces chaining them in any arbitrary way.

NLOptControl. I'm wondering if it's not a problem in the REPL because of the way precompilation works there -- you don't compile all of module Main at the same time like you do for a package's module. Contribute to MetalNinjas/julia-nlopt development by creating an account on GitHub. It seems like you'd be better off adding options to JuMP to generate an objective function that does printouts, store a trace of the objective-function values, etcetera, in a common way across backends, rather than having NLopt bindings for julia. 6, I keep getting the following errors: julia> Pkg.
