An Unexpected Journey: Towards Runtime Verification of Multiagent Systems and Beyond
The Trace Expression formalism derives from works started in 2012 and is
mainly used to specify and verify interaction protocols at runtime, but other
applications have been devised. More specically, this thesis describes how
to extend and apply such formalism in the engineering process of distributed
articial intelligence systems (such as Multiagent systems).
This thesis extends the state of the art through four dierent contributions:
1. Theoretical: the thesis extends the original formalism in order to represent
also parametric and probabilistic specications (parametric trace
expressions and probabilistic trace expressions respectively).
2. Algorithmic: the thesis proposes algorithms for verifying trace expressions
at runtime in a decentralized way. The algorithms have been
designed to be as general as possible, but their implementation and
experimentation address scenarios where the modelled and observed
events are communicative events (interactions) inside a multiagent system.
3. Application: the thesis analyzes the relations between runtime and static
verication (e.g. model checking) proposing hybrid integrations in both
directions. First of all, the thesis proposes a trace expression model
checking approach where it shows how to statically verify LTL property
on a trace expression specication. After that, the thesis presents a
novel approach for supporting static verication through the addition
of monitors at runtime (post-process).
4. Implementation: the thesis presents RIVERtools, a tool supporting the
writing, the syntactic analysis and the decentralization of trace expressions
Lambda-calculus and formal language theory
Formal and symbolic approaches have offered computer science many application fields. The rich and fruitful connection between logic, automata and algebra is one such approach. It has been used to model natural languages as well as in program verification. In the mathematics of language it is able to model phenomena ranging from syntax to phonology while in verification it gives model checking algorithms to a wide family of programs. This thesis extends this approach to simply typed lambda-calculus by providing a natural extension of recognizability to programs that are representable by simply typed terms. This notion is then applied to both the mathematics of language and program verification. In the case of the mathematics of language, it is used to generalize parsing algorithms and to propose high-level methods to describe languages. Concerning program verification, it is used to describe methods for verifying the behavioral properties of higher-order programs. In both cases, the link that is drawn between finite state methods and denotational semantics provide the means to mix powerful tools coming from the two worlds
Proceedings of Monterey Workshop 2001 Engineering Automation for Sofware Intensive System Integration
The 2001 Monterey Workshop on Engineering Automation for Software Intensive System Integration was sponsored by the Office of Naval Research, Air Force Office of Scientific Research, Army Research Office and the Defense Advance Research Projects Agency. It is our pleasure to thank the workshop advisory and sponsors for their vision of a principled engineering solution for software and for their many-year tireless effort in supporting a series of workshops to bring everyone together.This workshop is the 8 in a series of International workshops. The workshop was held in Monterey Beach Hotel, Monterey, California during June 18-22, 2001. The general theme of the workshop has been to present and discuss research works that aims at increasing the practical impact of formal methods for software and systems engineering. The particular focus of this workshop was "Engineering Automation for Software Intensive System Integration". Previous workshops have been focused on issues including, "Real-time & Concurrent Systems", "Software Merging and Slicing", "Software Evolution", "Software Architecture", "Requirements Targeting Software" and "Modeling Software System Structures in a fastly moving scenario".Office of Naval ResearchAir Force Office of Scientific Research Army Research OfficeDefense Advanced Research Projects AgencyApproved for public release, distribution unlimite
