WebbTheorem 2.1 implies that there always exists a fixed policy so that taking actions specified by that policy at each time step maximizes the discounted reward. The agent does not need to change policies with time. There is a similar result for the average reward case, see Theorem 8.1.2 in Puterman ().This insight reduces the question of finding the best … Webb9 feb. 2024 · We introduce a novel class of off-policy algorithms, batch-constrained reinforcement learning, which restricts the action space in order to force the agent …
