WebMar 24, 2024 · 4. Policy Iteration vs. Value Iteration. Policy iteration and value iteration are both dynamic programming algorithms that find an optimal policy in a reinforcement learning environment. They both employ variations of Bellman updates and exploit one-step look-ahead: In policy iteration, we start with a fixed policy.
