Runtime Adaptation for Actor Systems

We study the problem of extending RV techniques in the context of (asynchronous) actor systems, so as to be able to carry out a degree of system adaptation at runtime. We propose extensions to specification logics that provide handles for programming both monitor synchronisations (with individual actors), as well as the administration of the resp. adaptations once the triggering behaviour is observed. Since this added functionality allows the specifier to introduce erroneous adaptation procedures, we also develop static analysis techniques based on substructural type systems to assist the construction of correct adaptation scripts.
