Off-line test selection with test purposes for non-deterministic timed automata

Nathalie Bertrand ; Thierry Jéron ; Amélie Stainer ; Moez Krichen.

This article proposes novel off-line test generation techniques from non-deterministic timed automata with inputs and outputs (TAIOs) in the formal framework of the tioco conformance theory. In this context, a fi?rst problem is the determinization of TAIOs, which is necessary to foresee next enabled&nbsp;[&hellip;]

Stochastic Timed Automata

Nathalie Bertrand ; Patricia Bouyer ; Thomas Brihaye ; Quentin Menet ; Christel Baier ; Marcus Groesser ; Marcin Jurdzinski.

A stochastic timed automaton is a purely stochastic process defined on a timed automaton, in which both delays and discrete choices are made randomly. We study the almost-sure model-checking problem for this model, that is, given a stochastic timed automaton A and a property $\Phi$, we want to&nbsp;[&hellip;]

Controlling a population

Nathalie Bertrand ; Miheer Dewaskar ; Blaise Genest ; Hugo Gimbert ; Adwait Amit Godbole.

We introduce a new setting where a population of agents, each modelled by a finite-state system, are controlled uniformly: the controller applies the same action to every agent. The framework is largely inspired by the control of a biological system, namely a population of yeasts, where the&nbsp;[&hellip;]

Reconfiguration and Message Losses in Parameterized Broadcast Networks

Nathalie Bertrand ; Patricia Bouyer ; Anirban Majumdar.

Broadcast networks allow one to model networks of identical nodes communicating through message broadcasts. Their parameterized verification aims at proving a property holds for any number of nodes, under any communication topology, and on all possible executions. We focus on the coverability&nbsp;[&hellip;]
