The term,reinforcement learning,comes from behavior psychology that takes behavior leaming as trial and error,by which the states of environment are mapped into corresponding actions.First,the main algorithms,temporal difference, \%Q \%learning and adaptive heuristic critic,are roundly introduced.Then,the application of reinforcement leaming is presented.Finally,some present research projects of reinforcement learning are discussed.
