WebSolver-specific callback Ipopt provides a callback that can be used to log the status of the optimization during a solve. It can also be used to terminate the optimization by returning false. Here is an example: using JuMP, Ipopt, Test model = Model (Ipopt. 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.
Note that Ipopt requires that the linear solver is able to provide the inertia (number of positive and negative eigenvalues) of the symmetric matrix that is factorized. Furthermore, Ipopt can also use the HSL package MC19 for scaling of the linear systems before they are passed to the linear solver.
