Dear Andreas,

I am having trouble specifying the stopping criteria
that would work best for my case.

With IPOPT tol = 0.1 I have seen that problem
does not terminate unless the Objective has 
converged in its first 5-6 significant digits.
But from the 3rd significant digit up to the 
6th one, many unnecessary iterations take place
with many line searches as well. 

Is there any way of telling IPOPT to stop after
the objective has converged in its 3-4 significant
