Webbe greedy policy based on U 0. Evaluate π 1 and let U 1 be the resulting value function. Let π t+1 be greedy policy for U t Let U t+1 be value of π t+1. Each policy is an improvement until optimal policy is reached (another fixed point). Since finite set of policies, convergence in finite time. V.

WebMar 6, 2024 · Behaving greedily with respect to any other value function is a greedy policy, but may not be the optimal policy for that environment. Behaving greedily with respect to a non-optimal value function is not the policy that the value function is for, and there is no Bellman equation that shows this relationship. Web3. The h-Greedy Policy and h-PI In this section we introduce the h-greedy policy, a gen-eralization of the 1-step greedy policy. This leads us to formulate a new PI algorithm which we name “h-PI”. The h-PI is derived by replacing the improvement stage of the PI, i.e, the 1-step greedy policy, with the h-greedy policy. finished in sign language baby
