Aims and Scope

MAS and Complex Networks:

Multi Agent Systems (MAS) allow to study the emergence of systemic properties which result from the interaction of a large number of agents, rather than from single agents. Intelligence can be seen as such an emergent property. This means that the ability of a system to solve a problem, to optimize an outcome, or to adapt to a changing situation in a prospective manner may not be traced back to individual capabilities, but to the collective effort of many agents. A framework to model these MAS is provided by the complex networks approach, where agents are represented by nodes and their interactions are represented by links. Thus, the underlying network structure of a MAS plays a crucial role in explaining emergent properties. Networked agents, on the other hand, may be able to actively change this structure by forming new links or cutting existing ones. Consequently, there is not only a strong relation, but a coevolution in the dynamics of agents and their network of interactions.

The aim of this workshop is to investigate the role of networked agents in the emergence of systemic properties, notably emergent intelligence. Focus is on topics such as network formation among agents, feedback of network structures on agents dynamics, network-based collective phenomena, and emergent problem solving by networked agents.

Bridge Communities, Develop Commonalities:

Currently, it seems that research on MAS is still mostly focused on agents themselves, whereas networks of agents have received relatively little attention. The rapid development of various technologies, including those in ubiquitous computing, sensor networks, and grid computing will lead to systems consisting of a potentially very large number of agents. In these situations, the view of each agent is limited to its local environment, and the efficiency of the system is significantly affected by the network in which the agents are embedded. Thus, it is important to pay attention not only to agents themselves, but also to the structure and the dynamics of the network.

Traditionally, these topics have been addressed by researchers in the field of network science. Currently, however, network science has much more affinity to the community of complex systems research than to the one of MAS. The intention of this workshop is to change this by bridging the gap between the two research communities in complex networks and multi-agent systems.

Thus, the workshop shall contribute to the development of an active multi-disciplinary community by (i) increasing the mutual awareness of researchers in the MAS and complex network communities, (ii) building a foundation for combining agent-based modeling and complex networks, (iii) developing predictive methodologies that can be used to study the emergent intelligence of networked agents.

Overcome Limitations of Singular Approaches:

Research on complex networks focuses, among others, on the scale-free properties of various kinds of networks. The absense of a characteristic scale implies that the insights obtained can be scaled up to large systems. Such properties may be of use for the study of very large-scale MAS, where agents follow local rules under complex network constraints. Their high-dimensional, non-linear nature makes network-centric MAS difficult or impossible to analyze with traditional methods. Thus, combining MAS and complex networks could result into engineering methodologies to design large-scale complex agent networks.

So far, our capabilities to model, understand, and predict the behavior of networked agents do not fully meet the requirements of large-scale systems. In order to explain the, sometimes counter-intuitive, dynamics observed on the systemic level of large MAS, we need to better know the relation between emergent properties and the key mechanisms involved in shaping an agent's behavior. In this respect, computational models play a substantial role. The combined efforts in hardware development for simulating large MAS and the understanding of large-scale interaction models will allow us to reach the goal of developing a concise engineering methodology. The workshop is intended as an important step into this direction, by addressing the theoretical challenges of such large-scale networked agent models.

Topics of Interest

All are with respect to multi-agent systems and complex networks:

The WEIN Workshop series started as a Japanese initiative and has been part of AAMAS regularly since 2006. Recent proceedings have appeared, e.g., in the Springer Series on Studies in Computational Intelligence or in the International Transactions on Systems Science and Applications. WEIN 2010 will be the Fifth International Workshop on Emergent Intelligence on Networked Agents. One of WEIN's core goals is to bridge between the MAS and the complex network communities.
