WebMay 15, 2024 · The first-visit MC method estimates V π ( x) as the average of the returns following first visits to x, whereas the every-visit MC method averages the returns following all visits to x. MC Control Exploring Start The general idea of MC control is to use some version of Policy Iteration. WebMonte Carlo methods can thus be incremental in an episode-by-episode sense, but not in a step-by-step (online) sense. The first-visit MC method estimates v π ( s) as the average of the returns following first visits to s, whereas the every-visit MC method averages the returns following all visits to s.
