What’s Stochastic Optimal Control Problem? Abstract Recent advances on path integral stochastic optimal control [1],[2] provide new insights in the optimal control of nonlinear stochastic systems which are linear in the controls, with state independent and time invariant control transition This paper provides new insights into the solution of optimal stochastic control problems by means of a system of partial differential equations, which characterize directly the optimal control. 50 257 doi:10.1070/RM1995v050n02ABEH002054, S.
