An ordinal optimization approach to optimal control problems
We introduce an ordinal optimization approach to the study of optimal control law design. As illustration of the methodology, we find the optimal feedback control law for a simple LQG problem without the benefit of theory. For the famous unsolved Witsenhausen problem (1968, SIAM J. Control, 6(1)), a solution that is 50% better than the Witsenhausen solution is found.
