[Ipopt] Objective Value Return by Program

[Zhaori Bi]

Hi guys,

My Objective Value Return by Program (the inputs are variables) and there
is no objective function in my case and I use ADOL-C to calculate the
derivative automatically.

Problem is I found the IPOPT is not work in my case. It treats the
objective function as constant value. Namely,

obj_value = run_program(x[0]....x[10])
is equal to
obj_value = CONSTANT

Is there any methods to solve this problem?
