Hi, I am using IPOPT solver for a NLP optimization and I got an
infeasibility error due to restoration failure (attached file). I am not
familiar with programming in IPOPT. So, I would appreciate if anyone can
help me with specific details on how to fix it? I am using APMonitor
modeling language and Matlab as my interface to run.
Thanks
