Hi all, I am trying to use Julia's Ipopt interface for an optimization problem. I have two questions. Firstly, is it possible to only provide the objective function and starting values and not bother about the gradient, hessian, etc, or alternatively would providing the objective function and gradient suffice? I know that this greatly reduces the performance of the solver but is it possible? My function is very high dimensional and it would be very cumbersome to compute those manually. Secondly, would someone be able to explain how I could instead use the newly introduced autodiff to provide the gradient?
Any help is appreciated! Thank you
