Notes on value function iteration
WebWhile value iteration iterates over value functions, policy iteration iterates over policies themselves, creating a strictly improved policy in each iteration (except if the iterated policy is already optimal). Policy iteration first starts with some (non-optimal) policy, such as a random policy, and then calculates the value of each state of ... WebMay 22, 2016 · Policy iteration includes: policy evaluation + policy improvement, and the two are repeated iteratively until policy converges. Value iteration includes: finding optimal value function + one policy extraction. There is no repeat of the two because once the value function is optimal, then the policy out of it should also be optimal (i.e. converged).

Therefore, it is natural to approximate the value function using one of the flnite element methods. In this example, let’s use the easiest one for the ...
