WebFirst-visit Monte Carlo policy evaluation. R. S. Sutton and A. G. Barto: Reinforcement Learning: An Introduction 4 Monte Carlo Control •MC policy iteration: Policy evaluation using MC methods followed by policy improvement •Policy improvement step: greedify with respect to value (or action-value) function. MC Estimating Q? WebThe algorithm of first-visit MC prediction is given as follows: Let total_return ( s) be the sum of the return of a state across several episodes and N ( s) be the counter, that is, the number of times a state is visited across several episodes. Initialize total_return ( s) and N ( s) as zero for all the states. The policy is given as input. philip james hutchings
