Hi everyone,

I recently use Ipopt for my project. I try ma27 solver and its work very well. I also try ma57 with metis but I observe that the results are worst (more slow and worst objective function value). I also buy a license for pardiso and it is the same. In fact pardiso is worst than ma57 (with openmp on a quad core).

Did you know if it exist some papers or reports that present comparison results with Ipopt using different linear solver because it seems very strange to me why I observed this results?
