Discrete-time Approximation of Stochastic Optimal Control with Partial Observation

Yunzhang Li, Xiaolu Tan, Shanjian Tang

We consider a class of stochastic optimal control problems with partial observation, and study their approximation by discrete-time control problems. We establish a convergence res…
