Is there a possibility to add multiple ranges for a specific variable, for example 0.4 <= x <= 1.6 or x = 0? I would really appreciate if someone could help me out

Hi @ymayer2006,

If you're looking for "or x = 0" specifically, then use: https://jump.dev/JuMP.jl/stable/tutorials/linear/tips_and_tricks/#Semi-continuous-variables

p.s., these questions are better asked on our forum: https://jump.dev/forum. We try to reserve the GitHub issues for bug reports and feature requests.

Closing because I don't know if there is anything actionable to do here. If you have more usage questions, please ask on the forum :smile: https://jump.dev/forum
