Hello Kayan,

so you want to solve an optimal control problem with IpOpt?

Like: what is the best action u, given state x? (Maximize expected
reward or some such?)

I don't know if your approach is feasible at all, but if you intend
what I stated above, I think you should not make x part of your
optimization parameters, since you are interested in u. Then you have
a "normal" optimization problem, but with properties I am not aware of.

Best regards,
Philipp
