Abstract

We investigate extensions of CTL allowing to express quantitative requirements about an abstract notion of time in a simple discrete-time framework, and study the expressive power of several relevant logics.When only subscripted modalities are used, polynomial-time model checking is possible even for the largest logic we consider, while the introduction of freeze quantifiers leads to a complexity blow-up.
