WebIn the first visit method, after you reach that state (X) you start to sum the rewards until the end of the episode. If the state X appears again, you ignore it and don't start counting again. The value of the state X is the average sum for all episodes where X appears 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 … fluphenazine interactions
