[The octeract engine](https://octeract.gg/octeract-engine/) solved 100% of the Mittelmann MINLP benchmark.
It is a commercial software.
We have a free MINLP solver called Alpine.

How do they compare?
As a side note, why doesn’t JuMP list octeract as a commercial solver available?

Octeract is probably much, much faster. I wouldn’t be surprised if it was 10-100X faster.

Do they have an official interface? I guess we could add the NL file interface to [Installation Guide · JuMP](https://jump.dev/JuMP.jl/stable/installation/#Supported-solvers)

They support Julia.

This is just via our generic nl interface. But I’ve added octeract to our list of supported solvers
