In recent years auctions have become more and more important in the field of multiagent systems as useful mechanisms for resource allocation and task assignment. In many cases the Vickrey (second-price sealed-bid) auction is used as a protocol that prescribes how the individual agents have to interact in order to come to an agreement. We show that the Vickrey auction, despite its theoretical be...

The problem of development and application of the multiagent techniques for organizing mobile exploring agents' cooperative behavior is examined. The main problems related to design and operating of distributed decentralized homogeneous multi-agent systems with restricted local interaction between agents are analyzed. A number of collective behavior models (algorithmic, interpolational, entropi...

In recent times researchers have initiated investigating emotion as a collective property of groups, emphasizing the influence of combined emotions among group members on group processes. Within groups humans recognize and react emotionally to expressions of emotions of other group members. This paper uses a multi-agent-based approach to formalize and simulate such emotion contagion within groups.

Increasingly, agent teams are used in realistic and complex multiagent environments. In such environments, dynamic and complex changes in the environment require appropriate adaptation of the teamwork (collaboration) among team-members. As RoboCup proposes to provide multi-agent researchers with a standard test-bed for evaluation of methodologies, it is only natural to use it for investigating ...

Formal dialectic systems have been suggested as a means to model inter-agent communication in multi-agent systems. The formal dialectic systems of Hamblin are practical models for the computational implementation of such a system of argumentative dialogue. This paper introduces a formal framework for the specification of Hamblintype systems that has a range of benefits for theoretical work in t...

Many different problems are called distributed or multiagent planning problems. Existing approaches each deal with only a subset of these problems. Which properties are essential in determining a solution method for multiagent planning problems? We argue that mainly the facts that communication is limited, agents have private goals, and the frequency of the dependencies between agents have a si...

Evidence-based medicine relies heavily on the timely dissemination of ‘best evidence’ to a wide audience of health practitioners (Atkins and Louw, 2000). However, finding, assimilating and using this information resource effectively can be difficult. In this paper we describe an infrastructure for facilitating evidencebased health care using Agora a multi-agent system. This paper discusses a ne...

Over the last decade, methods for multiagent planning under uncertainty have increased in scalability. However, many methods assume value factorization or are not able to provide quality guarantees. We propose a novel family of influence-optimistic upper bounds on the optimal value for problems with 100s of agents that do not exhibit value factorization.

This paper proposes an agent-based collaborative architecture for collaborative work. This architectureis applied to knowledge-drivenprocess management, which often requires quick reconfiguration of applications. Using this architecture, an open multi-agent system is integrated with a virtual collaborativeenvironment. The virtual collaborativeenvironmentprovides the representation and managemen...
