How can you best describe the Bellman Equations for a Markov Reward Process (MRP)? A) The value of a state is the reward from that state plus the sum over the product of transition probabilities for the next n states. B) The value of a state is the sum over all actions, a, given the state, s of the policy, times the sum over the product of transition probabilities from the state to the next state, s’ and the reward...
