InferOpt.jl

Stable Dev Build Status Coverage Code Style: Blue Aqua QA

Overview

InferOpt.jl is a toolbox for using combinatorial optimization algorithms within machine learning pipelines.

It allows you to create differentiable layers from optimization oracles that do not have meaningful derivatives. Typical examples include mixed integer linear programs or graph algorithms.

Getting started

To install the stable version, open a Julia REPL and run the following command:

julia> using Pkg; Pkg.add("InferOpt")

To install the development version, run this command instead:

julia> using Pkg; Pkg.add(url="https://github.com/axelparmentier/InferOpt.jl")
