Webwith constant transition durations, which imply deterministic decision times in Deﬁnition 1. This assumption is mild since many discrete time sequential decision problems follow that assumption. A non-stationary policy ˇis a sequence of decision rules ˇ twhich map states to actions (or distributions over actions). Webproblem, we show the existence of a deterministic stationary optimal policy, whereas, for the constrained problems with N constraints, we show the existence of a mixed stationary optimal policy, where the mixture is over no more than N + 1 deterministic stationary policies. Furthermore, the strong duality result is obtained for the associated

WebA special case of a stationary policy is a deterministic stationary policy, in which one action is chosen with probability 1 for every state. A deterministic stationary policy can be seen as a mapping from states to actions: π: S→ A. For single-objective MDPs, there is WebIn many practical stochastic dynamic optimization problems with countable states, the optimal policy possesses certain structural properties. For example, the (s, S) policy in inventory control, the well-known c μ-rule and the recently discovered c / μ-rule (Xia et al.
