Solving the Reachability Problem for Branching Vector Addition Systems via Semilinear Inductive Invariants
Clotilde Bizière, Jérôme Leroux, Grégoire Sutre
In this paper, we solve the reachability problem for branching vector addition systems (BVAS), a long standing open problem. Our approach is based on semilinear inductive invariant…
On Parameterized Verification Over Tree Topologies
Romain Delpy, Anca Muscholl, Grégoire Sutre
Parameterized verification of finite-state processes with rendez-vous synchronization is notoriously undecidable when processes are linearly ordered. In this paper we study two kin…
A Forward-Only Construction of Semilinear Inductive Invariants for VAS
Clotilde Bizière, Jérôme Leroux, Grégoire Sutre
The reachability problem for Vector Addition Systems (VAS) is a central decision problem in the theory of infinite-state systems, first solved by Kosaraju and Mayr in the 1980s. An…
On the Reachability Problem for Two-Dimensional Branching VASS
Clotilde Bizière, Thibault Hilaire, Jérôme Leroux +1
Vectors addition systems with states (VASS), or equivalently Petri nets, are arguably one of the most studied formalisms for the modeling and analysis of concurrent systems. A cent…
