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. WebFeb 25, 2024 · The Newton iteration can diverge. The Newton iteration can diverge because we didn't provide exact/good/correct derivatives. The Newton iteration can diverge because the barrier parameters need tweaking. The Newton iteration can diverge/be so slow that iteration limit is reached before feasibility because the line search failed/needs tweaking. cycloplegics and mydriatics

Webinternal: max-norm of violation of internal equality constraints original: maximal constraint violation in original NLP; option _file _name: File name of options file (to overwrite default). By default, the name of the Ipopt options file is ”ipopt.opt” - or something else if specified in the IpoptApplication::Initialize call.

I would like to do so in order to reuse common calculations. In the MWE I show there are no common calculations, but the goal is to have a single function that can perform the three things depending on what is needed in each iteration (some iterations do not calculate the Hessian, for example). cyclopithecus
