Abstract

Point-based value iteration methods are a class of practical algorithms for solving the POMDP model. PBVI is a classical point-based value iteration method with low efficiency. FSVI can reduce the complexity and improve efficiency significantly by using the optimal strategy of the underlying MDP. However, it is not efficient in the large-scale POMDP problems. The paper proposed a probability-based value iteration on optimal state distribution algorithm for POMDP(PBVI-OSD). Du-ring the exploration, PBVI-OSD used the alias method to sample the action a* based on weighted QMDP function and sample the state based on b and the transition function. Then PBVI-OSD selected the observation z whose probability was greater than the threshold, and got the successor point b with great value from a* and z, which ensured the effect of value iteration. Experiment results of four benchmarks show that PBVI-OSD can achieve better global optimal solutions than FSVI and PBVI, especially in large-scale problems.
