Webb16 feb. 2024 · Performance difference. Q-learning directly learns the optimal policy because it maximises the reward with a greedy action selection strategy. This removes the chance that the agent uses an exploration step from the second step in de update function. SARSA can use an exploration step in the second step, because it keeps following the ε … Webb21 sep. 2024 · The reward scheme is very simple: The maze hands out a reward of 100 if the maze is solved, -1 if the agent tries to bump into an internal maze wall, and 0 otherwise. As for Sarsa, I coded it from scratch so it: Stores each state-action’s value in a dictionary (where the lookup is first by state, then by action).

Webb18 jan. 2024 · SARSA (State-Action-Reward-State-Action) is a Markov Decision Process Strategy learning method (MDP).
