This book constitutes the refereed proceedings of the Second German Conference on Multiagent Systems Technologies, MATES 2004, held in Erfurt, Germany, in September 2004.
The 22 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 60 submissions. The papers are organized in topical sections on learning and social agents, analysis and security, negotiation and control, agents and software engineering, simulation and agents, and policies and testing.
After the huge success of the first German Conference on Multiagent System Technologies (MATES) last year in Erfurt the German Special Interest Group on Distributed Artificial Intelligence together with the steering committee of MATES proudly organized and conducted this international conference for the second time.
The goal of the MATES conference is to constitute a high-quality platform for the presentation and discussion of new research results and system developments. It provides an interdisciplinary forum for researchers, users, and developers, to present and discuss the latest advances in research work, as well as prototyped or fielded systems of intelligent agents. The conference covers the complete range from theory to application of agent and multiagent technologies.
