The model checking fingerprints of CTL operators (1504.04708v2)
Published 18 Apr 2015 in cs.LO and cs.CC
Abstract: The aim of this study is to understand the inherent expressive power of CTL operators. We investigate the complexity of model checking for all CTL fragments with one CTL operator and arbitrary Boolean operators. This gives us a fingerprint of each CTL operator. The comparison between the fingerprints yields a hierarchy of the operators that mirrors their strength with respect to model checking.
