We present a methodology for the automatic verification of multi-agent systems against temporal-epistemic specifications derived from higher-level languages defined over convergent equational theories. We introduce a modality called rewriting knowledge that operates on local equalities. We discuss the conditions under which its interpretation can be approximated by a second modality that we introduce called empirical knowledge. Empirical knowledge is computationally attractive from a verification perspective. We report on an implementation of a technique to verify this modality with the open source model checker MCMAS. We evaluate the approach by verifying multi-agent models of electronic voting protocols automatically extracted from high-level descriptions.

Jones AV, Knapik M, Lomuscio A, et al., 2012, Group synthesis for parametric temporal-epistemic logic, 11th International Conference on Autonomous Agents and Multiagent Systems 2012, AAMAS 2012: Innovative Applications Track, Vol: 2, Pages: 880-887
We investigate parameter synthesis in the context of temporal-epistemic logic. We introduce CTLPK, a parametric extension to the branching time temporal-epistemic logic CTLK with free variables representing groups of agents. We give algorithms for automatically synthesising the groups of agents that make a given parametric formula satisfied. We discuss an implementation of the technique on top of the open-source model checker MCMAS and demonstrate its attractiveness by reporting the experimental results obtained.

Ezekiel J, Lomuscio A, Molnar L, et al., 2011, Verifying fault tolerance and self-diagnosability of an autonomous underwater vehicle, Pages: 1659-1664, ISSN: 1045-0823
We report the results obtained during the verification of Autosub6000, an autonomous underwater vehicle used for deep oceanic exploration. Our starting point is the Simulink/Matlab engineering model of the submarine, which is discretised by a compiler into a representation suitable for model checking. We assess the ability of the vehicle to function under degraded conditions by injecting faults automatically into the discretised model. The resulting system is analysed by means of the model checker MCMAS, and conclusions are drawn on the system's ability to withstand faults and to perform self-diagnosis and recovery. We present lessons learnt from this and suggest a general method for verifying autonomous vehicles.
Lomuscio A, Qu H, Russo F, 2011, Automatic data-abstraction in model checking multi-agent systems, Pages: 52-68, ISSN: 0302-9743
We present an automatic data-abstraction technique for the verification of the universal fragment of the temporal-epistemic logic CTLK. We show the correctness of the methodology and present an implementation operating on ISPL models, the input files for MCMAS, a model checker for multi-agent systems. The experimental results point to the attractiveness of the technique in a number of examples in the multi-agent systems domain. © 2011 Springer-Verlag.

Lomuscio A, Penczek W, Qu H, 2010, Partial order reductions for model checking temporal epistemic logics over interleaved multi-agent systems, Pages: 659-666, ISSN: 1548-8403
We investigate partial order reduction Tor model checking multi-agent systems by focusing on interleaved interpreted systems. These are a particular class of interpreted systems, a mainstream MAS formalism, in which only one action at the time is performed. We present a notion of stuttering-equivalence, and prove the semantical equivalence of stuttering-equivalent traces with respect to linear and branching time temporal logics for knowledge without the next operator. We give algorithms to reduce the size of the models before the model checking step and show preservation properties. We evaluate the technique by discussing the experimental results obtained against well-known examples in the MAS literature.

Boureanu I, Cohen M, Lomuscio A, 2010, Model checking detectability of attacks in multiagent systems, Pages: 691-698, ISSN: 1548-8403
Information security is vital to many multiagent system applications. In this paper we formalise the notion of detectability of attacks in a MAS setting and analyse its applicability. We introduce a taxonomy of detectability specifications expressed in temporal-epistemic logic. We illustrate the practical relevance of attack detectability in a case study applied to a variant of Kerberos protocol. We model-check attack detectability in automatically generated MAS models for security protocols.

Jones AV, Lomuscio A, 2010, Distributed BDD-based BMC for the verification of multi-agent systems, Pages: 675-682, ISSN: 1548-8403
We present a method of distributed model checking of multi-agent systems specified by a branching-time temporal-epistemic logic. We introduce a serial algorithm, central to the distributed approach, for combining binary decision diagrams with bounded model checking. The algorithm is based on a notion of "seed states" to allow for state-space partitioning. Exploring individual partitions displays benefits arising from the verification of partial state-spaces. When verifying both an industrial model and a scalable benchmark scenario the serial bounded technique was found to be effective. Results for the distributed technique demonstrate that it out-performs the sequential approach for falsifiable formulae. Experimental data indicates that increasing the number of hosts improves verification efficiency.

Lomuscio A, Ezekiel J, 2009, Combining fault injection and model checking to verify fault tolerance in multi-agent systems, Proceedings of the International Joint Conference on Autonomous Agents and Multiagent Systems, AAMAS, Vol: 1, Pages: 86-93, ISSN: 1548-8403
The ability to guarantee that a system will continue to operate correctly under degraded conditions is key to the success of adopting multi-agent systems (MAS) as a paradigm for designing complex agent based fault tolerant systems. In order to provide such a guarantee, practically usable tools and techniques for verifying fault tolerant MAS architectures are urgently required. In this paper we address this requirement by combining automatic fault injection with model check-ing to verify fault tolerance in MAS. We present a generic method to mutate a model of a correctly behaving system into a faulty one, and show how the mutated model can be used to reason about fault tolerance, which includes recovery from faults. The usefulness of the proposed method is demonstrated by injecting automatically a fault into a sender-receiver protocol, and verifying temporal and epis- Temic specifications of the protocol's fault tolerance using the MCMAS model checker.
