Webwith strong heuristics and an -greedy rollout policy succeeds at solving various table-top rearrangement tasks, including a sorting task of up to 100 cubes. The addressed sorting problem, however, differs from ours in two key aspects. First, for the sorting goal, explicit target locations for each class are provided as input.
WebPolicy improvement property Rollout can only improve the base policy. A single period Rollout is a policy iteration update If at decision time, we apply single period rollout to the base policy ¯µ, then our decision policy is the policy iteration update µ+ ∈G(J µ¯). It follows that J µ+ TJ ¯ J . 14
