# Verification for Timed Automata Extended with Unbounded Discrete Data Structures

@inproceedings{Quaas2014VerificationFT, title={Verification for Timed Automata Extended with Unbounded Discrete Data Structures}, author={Karin Quaas}, booktitle={CONCUR}, year={2014} }

We study decidability of verification problems for timed automata extended with unbounded discrete data structures. More detailed, we extend timed automata with a pushdown stack. In this way, we obtain a strong model that may for instance be used to model real-time programs with procedure calls. It is long known that the reachability problem for this model is decidable. The goal of this paper is to identify subclasses of timed pushdown automata for which the language inclusion problem and…

It is shown that the reachability relation of 1-clock TA can be expressed by a formula of polynomial size in the existential fragment of linear arithmetic, which improves on recent results from the literature.

Symbolic Monitoring against Specifications Parametric in Time and Data

- Computer ScienceCAV

This work proposes an automata-based formalism to monitor logs in the form of actions associated with time stamps and arbitrarily data values over infinite domains that is able to output answers symbolic in these parameters and in the log segments where the property is satisfied or violated.

This paper studies the decidability of universality for classes of timed automata with minimal resources, and considers restrictions on the number of states and clock constants, as well as the size of the event alphabet.

MTL-Model Checking of One-Clock Parametric Timed Automata is Undecidable

It is proved that MTL-model checking for parametric timed automata is undecidable, even if the automaton uses only one clock and one parameter and is deterministic.

It is shown that the satisfiability problem for MTL over finite timed words is decidable, with non-primitive recursive complexity, and that model checking the safety fragment of MTL-which includes invariance and time-bounded response properties-is also decidable.
