Model Checking CTL Properties of Pushdown Systems
نویسنده
چکیده
A pushdown system is a graph G(P ) of configurations of a pushdown automaton P . The model checking problem for a logic L is: given a pushdown automaton P and a formula α ∈ L decide if α holds in the vertex of G(P ) which is the initial configuration of P . Computation Tree Logic (CTL) and its fragment EF are considered. The model checking problems for CTL and EF are shown to be EXPTIME-complete and PSPACE-complete, respectively.

Pushdown Module Checking
Model checking is a useful method to verify automatically the correctness of a system with respect to a desired behavior, by checking whether a mathematical model of the system satisfies a formal specification of this behavior. Many systems of interest are open, in the sense that their behavior depends on the interaction with their environment. The model checking problem for finite-state open s...
متن کاملµ-calculus Pushdown Module Checking with Imperfect State Information
The model checking problem for open systems (module checking) has recently been the subject of extensive study. The problem was first studied by Kupferman, Vardi, and Wolper for finite-state systems and properties expressed in the branching time logicsCTL and CTL∗. Further study continued mainly in two directions: considering systems equipped with a pushdown store, and considering environments ...
متن کاملUndecidability of model-checking branching-time properties of stateless probabilistic pushdown process
In this paper, we settle a problem in probabilistic verification of infinite–state process (specifically, probabilistic pushdown process). We show that model checking stateless probabilistic pushdown process (pBPA) against probabilistic computational tree logic (PCTL) is undecidable.
متن کاملEfficient CTL Model-Checking for Pushdown Systems
Pushdown systems (PDS) are well adapted to model sequential programs with (possibly recursive) procedure calls. Therefore, it is important to have efficient model checking algorithms for PDSs. We consider in this paper CTL model checking for PDSs. We consider the “standard” CTL model checking problem where whether a configuration of a PDS satisfies an atomic proposition or not depends only on t...
متن کاملModel Checking Extended Computation Tree Logic
Computation Tree Logic is widely used for modelling the behaviour of simple systems over time, but its expressive power is limited. More powerful logics such as CTL* and the modal mu-calculus have the disadvantage that their model-checking problems are comparatively intractable, and they can be unintuitive. A recent contribution by Axelsson et al. introduces the `Extended CTL' family of logics,...
