Web22 nov. 2024 · c T ( t ⋅ y) = t ⋅ c T y = t v > v. If you look more closely at the steps above you will see that c T y keeps increasing proportionally as we increase t which means that c T y → ∞ as t → ∞. So a linear program is unbounded if it has a feasible solution (our x ∗ above) and a vector y that satisfies conditions (1) and (2).

WebThis may occur because there are some steps in presolve that prevent us from distinguishing between infeasibility and unboundedness. In order to determine if the model is infeasible or unbounded, you should set the DualReductions parameter to 0, call reset on the model, and optimize once again. Web21 sep. 2024 · Hence, solve the problem without an objective. If it shows infeasibility, unboundedness is perhaps not the case (or you have a completely flawed model which is both infeasible and unbounded (without the infeasible constraints). If infeasibility is detected, you have to sort out the infeasibility first.
