Taming Past LTL and Flat Counter Systems
Abstract. Reachability and LTL model-checking problems for flat counter systems are known to be decidable but whereas the reachability problem can be shown in NP, the best known c...

On Reachability for Hybrid Automata over Bounded Time
This paper investigates the time-bounded version of the reachability problem for hybrid automata. This problem asks whether a given hybrid automaton can reach a given target locat...

Space-Efficient Algorithms for Reachability in Surface-Embedded Graphs
We consider the reachability problem for a certain class of directed acyclic graphs embedded on surfaces. Let G(m, g) be the class of directed acyclic graphs with m = m(n) source ...

Robust Computations with Dynamical Systems
Abstract. In this paper we discuss the computational power of Lipschitz dynamical systems which are robust to infinitesimal perturbations. Whereas the study in [1] was done only f...

Solvability of the Halting and Reachability Problem for Binary 2-tag Systems
In this paper we will provide a detailed proof of the solvability of the halting and reachability problem for binary 2-tag systems. We will furthermore prove that an important sub...

Reachability in Live and Safe Free-Choice Petri Nets is NP-Complete
The complexity of the reachability problem for live and safe free-choice Petri nets has been open for several years. Several partial results seemed to indicate that the problem is...

Reachability results for timed automata with unbounded data structures
Systems of Data Management Timed Automata (SDMTAs) are networks of communicating timed automata with structures to store messages and functions to manipulate them. We prove the dec...

Analyzing Asynchronous Programs with Preemption
ABSTRACT. Multiset pushdown systems have been introduced by Sen and Viswanathan as an adequate model for asynchronous programs where some procedure calls can be stored as tasks to ...

When Is Reachability Intrinsically Decidable?
A graph H is computable if there is a graph G = (V, E) isomorphic to H where the set V of vertices and the edge relation E are both computable. In this case G is called a computabl...
