On-policy learning algorithm

WebOn-policy algorithms cannot separate exploration from learning and therefore must confront the exploration problem directly. We prove convergence results for several related on-policy algorithms with both decaying exploration and persistent exploration.

Q-Learning Algorithm: From Explanation to Implementation
