Using ANTIGONE from Julia



I’ve been investigating the various options for (globally optimal) MINLP in Julia, and ANTIGONE looks like a nice option. I’m curious if anyone has any experience using it from Julia.

At first glance, it looks like this will be difficult, as ANTIGONE appears to only support GAMS models, and I can’t find any JuMP-GAMS interface. It also looks like converting from .nl to GAMS is nontrivial. NEOS does support ANTIGONE, but only through GAMS file uploads, which seems like it doesn’t resolve the issue.

Am I missing anything? Any suggestions on the best path forward?

Or, perhaps, what is your favorite MINLP solver? So far on my list I have:

  • COUENNE: easy to use, compatible with JuMP, but appears to perform poorly
  • SCIP: also compatible with JuMP, but haven’t evaluated its performance
  • BARON: compatible with JuMP, but expensive. Currently waiting for a license
  • LINDOGlobal: GAMS-only


  • POD.jl: native Julia, with JuMP support


This package provides a way to access any solver that supports AMPL NL files,

You might also consider this native Julia global solver,


Thanks! Unfortunately, I don’t think ANTIGONE itself supports AMPL NL files, and I can’t find any clear way to transform a NL model into a GAMS one.

I’ve played around with POD.jl a bit in the past, but forgot to add it to the list. I’ll fix that now.
