WebDeterministic definition, following or relating to the philosophical doctrine of determinism, which holds that all facts and events are determined by external causes and follow … WebThe goal is to learn a deterministic stationary policy ˇ, which maps each state to an action, such that the value function of a state s, i.e., its expected return received from time step t and onwards, is maximized. The state-dependent value function of a policy ˇin a state s is then Vˇ(s) = E ˇ ˆX1 k=0 kr t+k+1 js t= s ˙; (1) where

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 WebJun 27, 2024 · There are problems where a stationary optimal policy is guaranteed to exist.

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.
