WebMar 15, 2024 · In the following pages (p.84-85) of RL and Optimal Control book by D.Bertsekas, he is talking about base heuristic" and a "rollout algorithm" based on this base heuristic. However, I am very confused because based on Figure 2.4.2, it seems that rollout algorithm and base heuristics are the same things. WebWe propose a novel approach, called parallel rollout, to solving (partially observable) Markov decision processes. Our approach generalizes the rollout algorithm of Bertsekas and Castanon (1999) by rolling out a set of multiple heuristic policies rather than a single policy. In particular, the parallel rollout approach aims at the class of problems where we …
