The paper entitled “Verification of indefinite-horizon POMDPs” by Alexander Bork, Sebastian Junges (UC Berkeley), Joost-Pieter Katoen and Tim Quatmann has been accepted for the 18th Int. Symp. on Automated Technology for Verification and Analysis (ATVA 2020). The key idea is to use abstractions of belief states and apply an abstraction-refinement strategy to verify unbounded reachability properties.
