Language support for verifying reconfigurable interacting systems

Reconfigurable interacting systems consist of a set of autonomous agents, with integrated interaction capabilities that feature opportunistic interaction. Agents seemingly reconfigure their interaction interfaces by forming collectives and interact based on mutual interests. Finding ways to design and analyse the behaviour of these systems is a vigorously pursued research goal. In this article, we provide a modelling and analysis environment for the design of such system. Our tool offers simulation and verification to facilitate native reasoning about the domain concepts of such systems. We present our tool named R-CHECK (please find the associated toolkit repository here: https://github.com/dsynma/recipe). R-CHECK supports a high-level input language with matching enumerative and symbolic semantics and provides modelling convenience for features such as reconfiguration, coalition formation, and self-organisation. For analysis, users can simulate the designed system and explore arising traces. Our included model checker permits reasoning about interaction protocols and joint missions.
