[Ipopt] Ipopt tuning for Quadratic Problem

[Schulz, Christian]

Hi,
we are trying to use Ipopt 3.8.0 for a convex quadratic problem.
We observed the following:
1) mehrotra_algorithm yes, does not work, i.e. causes an exception after some steps
2) changing mu_startegy to adaptive does not result in a significantly speed up
Are there any default values to get the most out of Ipopt for convex quadratic problem?
Thank You,
Christian
