Web3 de dez. de 2024 · In this work, we introduce a variational quantum algorithm that uses classical Markov chain Monte Carlo techniques to provably converge to global minima. These performance gaurantees are derived from the ergodicity of our algorithm's state space and enable us to place analytic bounds on its time-complexity. We demonstrate … Web24 de mar. de 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.
