[Ipopt] Why ipopt needs so many iterations when starting from the optimal solution?

[Gianpaolo Gulletta]

Hi everybody,

 

I realized that the performance of the algorithm Ipopt decreases when it
starts either from the optimal solution or from very closely.

I saw that the problem has already been addressed here
<https://www.or-exchange.org/questions/1268/why-ipopt-needs-so-many-iteratio
ns-when-starting-from-the-optimal-solution>  but I am still looking for the
answer.

 

Can anyone help? 

 

Thank you.

 

Regards,

 

Gianpaolo Gulletta
