[Ipopt] Is Ipopt able to solve complementary constrains?

[Stefan Vigerske]

Hi,

no, the current Ipopt versions do not include special features to handle 
complementarity constraints.

The old no-longer-maintained Ipopt-Fortran version has something. It is 
still available at  http://www.coin-or.org/Ipopt/ipopt-fortran.html
but not sure how easy it is to get it running.
