This book constitutes the thoroughly refereed post-proceedings of the Third International Workshop on Engineering Societies in the Agents World, ESAW 2003, held in Madrid, Spain in September 2002. The 20 revised full papers presented were carefully selected from 35 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on views, models, engineering, and modeling and design.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Engineering Societies in the Agents World, ESAW 2004, held in Toulouse, France, in October 2004. The 23 revised full papers presented together with an invited paper went through two rounds of reviewing and improvement and were carefully selected from 48 initial submissions. The papers are organized in topical sections on roles, organizations, and institutions for agents; social issues in multi-agent systems; cooperation and collective behavior in agent societies; methodologies and platforms for agent-oriented engineering; agent-oriented simulation; and models for multi-agent systems.

This book constitutes the thoroughly refereed post-proceedings of the 6th International Workshop on Engineering Societies in the Agents World, ESAW 2005. The book presents 15 revised full papers together with 3 invited papers, organized in topical sections on agent oriented system development, methodologies for agent societies, deliberative agents and social aspect, agent oriented simulation, adaptive systems, coordination, negotiation, protocols, and agents, networks and ambient intelligence.

The fourth internationalworkshop,“EngineeringSocietiesin the Agents World” (ESAW 2003) was a three-dayevent that took place at the end of October 2003. After previous events in Germany, the Czech Republic, and Spain, the workshop crossed the Channel, to be held at the premises of Imperial College, London. The steady increase in the variety of backgrounds of contributing sci- tists, fascinating new perspectives on the topics, and number of participants, bespeaks the success of the ESAW workshop series. Its idea was born in 1999 among members of the working group on “Communication, Coordination, and Collaboration” of the ?rst lease of life of the European Network of Excellence on Agent-Based Computing, AgentLink, out of a critical discussion about the general mindset of the agent community. At that time, we felt that proper c- siderationsofsystemicaspectsofagenttechnologydeployment,suchasackno- edgement of the importance of the social and environmental perspectives, were sorely missing: a de?ciency that we resolved should be addressed directly by a new forum.

This book constitutes the thoroughly refereed post-proceedings of the Second International Workshop on Engineering Societies in the Agents World, ESAW 2001, held in Prague, Czech Republic in July 2001. The 12 revised full papers presented together with a survey by the volume editors were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on foundations of engineering with agents, logics and languages for MAS engineering, and agent middleware and applications.

This book constitutes the thoroughly refereed post-proceedings of the First International Workshop on Engineering Societies in the Agents World, ESAW 2000, held in Berlin, Germany in August 2000. The 10 revised full papers presented were carefully reviewed and selected for inclusion in the book; they are organized in topical sections on emerging issues in multi-agent systems engineering, coordination models and technologies for multi-agent systems, and methodologies and tools.

The 10th international workshop “Engineering Societies in the Agents’ World” (ESAW 2009), was held in Utrecht, The Netherlands, during November 18–20, 2009. In the tradition of its predecessors, ESAW 2009 was committed to the idea of multi-agent systems (MAS) as highly interconnected societies of agents, paying particular attention to the social aspects, methodologies and software infrastructures that tackle the emergent complexities of MAS. The idea for the ESAW workshop series was born 10 years ago, in 1999, among the members of the working group on “Communication, Coordination and Collaboration” of AgentLink, the 1st European Network of Excellence on Agent-Based Computing, out of a critical discussion about the general mi- set of the agents community. Central to this discussion is the need for proper consideration of systematic aspects of MAS, acknowledging the importance of a multi-disciplinary approach, that takes into account the social, environmental and technological perspectives. These issues that are as actual today as they were in 1999, which is con?rmed by the steady interest in the ESAW workshop series that previous editions took place in: – Berlin, Germany, 2000 (LNAI 1972) – Prague, Czech Republic, 2001 (LNAI 2203) – Madrid, Spain, 2002 (LNAI 2577) – London, UK, 2003 (LNAI 3071) – Toulouse, France, 2004 (LNAI 3451) – Kusadasi, Turkey, 2005 (LNAI 3963) – Dublin, Ireland, 2006 (LNAI 4457) – Athens, Greece, 2007 (LNAI 4995) – Saint-Etienne, France, 2008 (LNAI 5485) This10thworkshopwasdevotedtothediscussionoftechnologies,methodologies and models for the engineering of complex applications based on MAS, and broughttogetherresearchersandcontributionsfrombothwithinandoutsidethe agents’?eld–fromsoftwareengineering,distributedsystems,socialsciences,and
