WebNov 18, 2024 · Since the greedy policy is optimal, all the policies must have the same state values as the greedy one. The reason that a policy may choose other actions other than the greedy action and remains optimal is other actions have the same action values as the greedy one; otherwise, the state value will decrease. $\endgroup$

WebMay 22, 2016 · In policy iteration algorithms, you start with a random policy, then find the value function of that policy (policy evaluation step), then find a new (improved) policy based on the previous value function, and so on. In this process, each policy is guaranteed to be a strict improvement over the previous one (unless it is already optimal). Given a … WebPolicy iteration first starts with some (non-optimal) policy, such as a random policy, and then calculates the value of each state of the MDP given that policy — this step is called the policy evaluation. It then updates the …
