I suggest you use gams studio to figure out which equations or inequalities have a violation of 1.25e+01 and try to see what's making them so hard to satisfy. If 1.25e+01 is an infeasibility you would accept, you can scale the equation so that this value lies around 1e-8 and repeat until all equations are properly scaled. |

Hi there,
I am using IPOPT to solve a NLP problem for which the log file is given below.
It is understood from the log that even after
maxiter
=1500, convergence is not reached. Also,Overall NLP error
andinf_du
are very large. Hence, I am wondering whether alternative approaches could be utilised, e.g., tuning parameterstol
,accept_tol
so that proper convergence can be attained.Any help would be appreciated.
