Researchers have developed a new framework for analyzing Restart POMDPs (Partially Observable Markov Decision Processes) on general Borel state spaces. This framework reduces the problem to a fully observed MDP by using a sufficient-statistic representation that includes the last observed state and the time elapsed since the last restart. Under specific cost deterioration conditions, the study proves that optimal policies exhibit a threshold structure in elapsed time for both discounted and total undiscounted cost criteria. Further analysis shows that for partially ordered state spaces with stochastically monotone kernels, the optimal threshold decreases as the state increases. For average cost criteria, analogous threshold results are established using the vanishing discount approach, provided certain ergodicity and transient gain domination assumptions are met. AI
