We present a framework for verifying temporal and epistemic properties of multi-agent systems by means of bounded model checking. We use interpreted systems as underlying semantics. We give details of the proposed technique, and show how it can be applied to the "attacking generals problem", a typical example of coordination in multi-agent systems.

In the last few years we have witnessed a surge of business-to-consumer and business-to-business commerce operated on the Internet. However, most current electronic commerce systems are little more than electronic catalogues that allow a user to purchase a product under predetermined and inflexible terms and conditions. We believe that in the next few years we will see a new generation of electronic commerce systems emerge, based on automated negotiation. In this paper, we identify the main parameters on which any automated negotiation depends. To show the applicability of our classification framework, we use it to categorise a representative sample of some of the most prominent negotiation models that exist in the literature.

The proceedings of the third UK Workshop on Multi-Agent systems (UKMAS 2001) held at St Catherine's College, Oxford were discussed. A method for solving sequential multi-agent decision problems by allowing agents to reason explicitly about specific coordination mechanisms was proposed. An adaptive organizational policy known as task and resource allocation in computational economy (TRACE), incorporating task and resource allocation for multi-agent systems that operate under time constraints and load variations was also proposed. An object-oriented extension of the multi-threaded Qu-Prolog language developed at Imperial College was also presented.

In the last few years we witnessed a surge of business-to-consumer and business-to-business commerce operated on the Internet. However many of these systems are often nothing more than electronic catalogues on which the user can choose a product which is made available for a fixed price. This modus operandi is clearly failing to exploit the full potential of electronic commerce. Against this background, we argue here that in the next few years we will see a new generation of systems emerge, based on automatic negotiation. In this paper we identify the main parameters on which any automatic negotiation depends. This classification schema is then used to catagorise the subsequent papers in this book that focus on automatic negotiation.

Lomuscio A, Ryan M, 2000, A spectrum of modes of knowledge sharing between agents, Pages: 13-26, ISSN: 0302-9743
© Springer-Verlag Berlin Heidelberg 2000. The logic S5nis widely used as the logic of knowledge for ideal agents in a multi-agent system. Some extensions of S5nhave been proposed for expressing knowledge sharing between the agents, but no systematic exploration of the possibilities has taken place. In this paper we present a spectrum of degrees of knowledge sharing by examining and classifying axioms expressing the sharing. We present completeness results and a diagram showing the relations between some of the principal extensions of S52and discuss their usefulness. The paper considers the case of a group of two agents of knowledge.
Lomuscio AR, Meyden Van Der R, Ryan M, 2000, Knowledge in Multiagent Systems: Initial Configurations and Broadcast, Pages: 247-284, ISSN: 1529-3785
The semantic framework for the modal logic of knowledge due to Halpern and Moses provides a way to ascribe knowledge to agents in distributed and multiagent systems. In this paper we study two special cases of this framework: full systems and hypercubes. Both model static situations in which no agent has any information about another agent's state. Full systems and hypercubes are an appropriate model for the initial configurations of many systems of interest. We establish a correspondence between full systems and hypercube systems and certain classes of Kripke frames. We show that these classes of systems correspond to the same logic. Moreover, this logic is also the same as that generated by the larger class of weakly directed frames. We provide a sound and complete axiomatization, S5WDn, of this logic, and study its computational complexity. Finally, we show that under certain natural assumptions, in a model where knowledge evolves over time, S5WDn characterises the properties of knowledge not just at the initial configuration, but also at all later configurations. In particular, this holds for homogeneous broadcast systems, which capture settings in which agents are initially ignorant of each others local states, operate synchronously, have perfect recall, and can communicate only by broadcasting. © 2000, ACM.
