[Ipopt] nonlinear optimization problem error

[Barry Barrios]

Hi,

I've a nonlinear optimization problem with several constraints, but the
solver gave this error:

EXIT: Converged to a point of local infeasibility. Problem may be
infeasible.
WARNING - Loading a SolverResults object with a warning status into
model=unknown; message from solver=Ipopt 3.11.1\x3a Converged to a locally
infeasible point. Problem may be infeasible.
WARNING - Loading a SolverResults object with a warning status into
model=unknown; message from solver=Ipopt 3.11.1\x3a Converged to a locally
infeasible point. Problem may be infeasible.


I was wondering if there's a multi-start option or if not, how can one
implement one, or if there's a way to use multi-start to escape from this
convergence problem.

Best,
Barry
