WebCliff Walking Code Environment Sarsa, Expected Sarsa Q-learning Visualization Cliff Walking This gridworld example compares Sarsa and Q-learning, highlighting the difference between on-policy (Sarsa) and off-policy (Q-learning) methods. Consider the … WebUnfortunately, this results in its occasionally falling off the cliff because of the -greedy action selection. Sarsa, on the other hand, takes the action selection into account and learns the longer but safer path through the upper part of the grid.
