 Hello,
 I have no hessian information so I have modified in the testproblem
 HS071_NLP::eval_h  to return false as a first test. I get the message:
 -------------------
 NOTE: You are using Ipopt by default with the MUMPS linear solver.
       Other linear solvers might be more efficient (see Ipopt
 documentation).


 This is Ipopt version 3.5.5, running with linear solver mumps.

 Option hessian_information is not chosen as limited_memory, but eval_h
 returns false.
 Exception of type: OPTION_INVALID in file "IpTNLPAdapter.cpp" at line 927:
  Exception message: eval_h is called but has not been implemented

 EXIT: Invalid option encountered.
 ----------------

 what is my mistake? It seems, that option hessian_information does not
 exists:

 Exception of type: OPTION_INVALID in file "IpOptionsList.cpp" at line 617:
  Exception message: Read Option: "hessian_information". It is not a valid
 option. Check the list of available options.


 Thanks
 Klingenberg
