Reinforcement Learning is Direct Adaptive Optimal Control Richard S. Sulton, Andrew G. Barto, and Ronald J. Williams Reinforcement learning is one of the major neural-network approaches to learning con- trol. • If the next state and/or immediate reward functions are stochastic, then the r(t)values are random variables and the return is defined as the expectation of this sum • If the MDP has absorbing states, the sum may actually be finite.
