WebApr 21, 2024 · Try another solver such as m.options.SOLVER=1 (APOPT) to verify an infeasibility. – John Hedengren May 6, 2024 at 15:40 1 APOPT solves and produces a larger Maximized Objective as shown above, but still returns a Solution Not Found error. Could adjusting any of the tolerance values avert this error? – Fonnie May 6, 2024 at 22:46 1 WebSep 27, 2024 · That IPOPT message means that IPOPT could not find a feasible solution to your problem. The reason could be either that: Once you set that value below 30, IPOPT can no longer find that basin of attraction (or that basin vanishes). Another feasible solution might exist (unless your problem is convex), but IPOPT can't find it.
