Thanks. I was aware that some solvers support multiple solutions, but given the free ones don’t I don’t really count it. Likewise sensitivity analysis for JuMP is somewhat limited. It allows you to adjust the RHS side of the constraints and the objective function coefficients. Mine allows you to adjust these and:
- The constraint coefficients.
- Add new variable(s).
- Add new constraint(s).
I will admit, I did not realize one could determine whether the problem was infeasible or unbounded with JUMP, so thanks for correcting me there.
