WebAttempt One: Approximate Policy Iteration (API) Given the current policy πt, let’s act greedily wrt π under dπ t μ i.e., let’s aim to (approximately) solve the following program: … WebMDPs and value iteration. Value iteration is an algorithm for calculating a value function V, from which a policy can be extracted using policy extraction. It produces an optimal policy an infinite amount of time. For medium-scale problems, it works well, but as the state-space grows, it does not scale well.
