[Ipopt] slow convergence

[Juan Carlos Lopez Alfonso]

Hi all,

I have changed the stop conditions and I am sure that the
implementation of my algorithm is correct. I have tested the results
with a small problems and the results are correct, but when I execute
my big problem the convergence is very slow and I dont know the
reason. Is very difficult to test my algorithm, and for example I have
one of them running for more than 2 days.

someone can give any idea to solve this problem? Is normal this behavior?
Best regards and thank you in advance
Juan Carlos
