WebAug 21, 2024 · First-visit MC. The first time $s$ is visited in an episode is referred as the first visitto $s$. The method estimates $v_\pi(s)$ as the average of the returns that have followed the first visitto $s$. Every-visit MC. The method estimates $v_\pi(s)$ as the average of the returns that have followed all visits to to $s$. 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
