Bounded Reachability Problems are Decidable in FIFO Machines [PDF]

open access: yesLogical Methods in Computer Science, 2022
The undecidability of basic decision problems for general FIFO machines such as reachability and unboundedness is well-known. In this paper, we provide an underapproximation for the general model by considering only runs that are input-bounded (i.e.
