Hello everybody,

I’m looking for a julia package to solve : **mixed integer nonlinear problem with three objectives.**

thank you.

Hi there,

you can take a look at [https://github.com/anriseth/MultiJuMP.jl](https://github.com/anriseth/MultiJuMP.jl), an extension of JuMP to multiple objectives. Combine that with a MIP solver and it should do it.

Your other solution would be to program yourself a multi-objective optimization technique, such as \epsilon -constraint, which I believe can build your whole Pareto front for three objectives in most situations.
