First-visit mc method
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.
