“…We evaluate our algorithms on three main classes of benchmarks, namely Fischer's protocol [31], an adaptive cruise controller [30], and the TTEthernet protocol [9]. For each class, we consider a linear version and a non-linear version, as well as for each a safe version and an unsafe version.…”

“…Second, we achieve greater practical performance against the state-of-the-art techniques for the time-unbounded reachability of even LHA. We evaluate our tool on multiple scaling and linear and non-linear variants of three different benchmarks, namely Fischer's protocol [31], the TTEthernet protocol [9], and an adaptive cruise controller [30].…”

Abstract. Template polyhedra generalize intervals and octagons to polyhedra whose facets are orthogonal to a given set of arbitrary directions. They have been employed in the abstract interpretation of programs and, with particular success, in the reachability analysis of hybrid automata. While previously, the choice of directions has been left to the user or a heuristic, we present a method for the automatic discovery of directions that generalize and eliminate spurious counterexamples. We show that for the class of convex hybrid automata, i.e., hybrid automata with (possibly nonlinear) convex constraints on derivatives, such directions always exist and can be found using convex optimization. We embed our method inside a CEGAR loop, thus enabling the time-unbounded reachability analysis of an important and richer class of hybrid automata than was previously possible. We evaluate our method on several benchmarks, demonstrating also its superior efficiency for the special case of linear hybrid automata.

This report presents results of a friendly competition for formal verification of continuous and hybrid systems with piecewise constant dynamics. The friendly competition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2018. In this second edition, five tools have been applied to solve five different benchmark problems in the category for piecewise constant dynamics: BACH, Lyse, PHAVer, PHAVer-lite, and VeriSiMPL. Compared to last year, a new tool has participated (PHAVer-lite) and a benchmark has been made more complex (Dutch Railway Network). The result is a snapshot of the current landscape of tools and the types of benchmarks they are particularly suited for. Due to the diversity of problems, we are not ranking tools, yet the presented results probably provide the most complete assessment of tools for the safety verification of continuous and hybrid systems with piecewise constant dynamics up to this date.

This report presents results of a friendly competition for formal verification of continuous and hybrid systems with linear continuous dynamics. The friendly competition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2019. In its third edition, three tools have been applied to solve three different benchmark problems in the category ofbounded model checking of hybrid systems with piecewise constant dynamics (in alphabetical order): BACH, HyDRA, and XSpeed. Compare to last year, HyDRA is equipped with new optimization techniques and the performance is improved accordingly. This report is a snapshot of the current landscape of tools and the types of benchmarks they are particularly suited for. Due to the diversity of problems, we are not ranking tools and we also welcome more tools to join in this friendly competition in the future event.
