My apologies for the oversight! The [paper, page 20](https://arxiv.org/pdf/1904.02703) that applied the mixed-integer problem formulation used `GLPK`. Based on your insightful comment [here](https://discourse.julialang.org/t/is-glpk-still-maintained-relevant/116950/4), I now understand that we should use `HIGHS` instead 🙂 Thank you for your help!
