Abstract

We report on recent progress in the study of infinite transition systems for which interesting properties (like reachability of designated states) can be checked algorithmically. Two methods for the generation of such models are discussed: the construction from simpler models via operations like unfolding and synchronized product, and the internal representation of state spaces by regular sets of words or trees.
