I made a couple of changes so that it should work with the latest versions of JuMP and the solvers. You should be able to install it via my branch: [Bump compat versions to support JuMP v1 by odow · Pull Request #14 · madeleineudell/SigmoidalProgramming.jl · GitHub](https://github.com/madeleineudell/SigmoidalProgramming.jl/pull/14)

But note that SigmoidalProgramming is old, has no tests, and is not supported. I’ll suggest again that the best course of action is for you to download the code and fix it locally:

> Do you have a reproducible example? This just looks like a bug. It looks like [GitHub - madeleineudell/SigmoidalProgramming.jl: Julia Package for Sigmoidal Programming](https://github.com/madeleineudell/SigmoidalProgramming.jl) hasn’t been updated in a number of years, so I wouldn’t expect this to get fixed unless you download and edit the code yourself.
