Mark d'Inverno has been working in the field of agent-based systems for well over 10 years and is currently Professor of Computer Science in the Cavendish School of Computer Science at the University of Westminster. He gained a BA in Mathematics in 1986 and an MSc in Computation in 1988 both from Oxford University, and in 1998 was awarded a PhD from University College London. He has published numerous papers in the area and is an expert in formal sepcification of agent systems. Prof d'Inverno is a founder of the UKMAS workshops, has chaired two UKMAS wortkshops and is a member of the UKMAS Steering Committee. He sits on several conference and workshop programme committees. Michael Luck is a Senior Lecturer in the Intelligence, Agents and Multimedia Group in the School of Electronics and Computer Science at the University of Southampton, UK. He has worked in the field of agent technology and multi-agent systems for over ten years, having previously led the Agent-Based Systems Group at the University of Warwick for seven years, and having gained his PhD from University College London in 1993 for work on agent-based discovery. Dr Luck is a co-founder of the UK Special Interest Group on Multi-Agent Systems, and currently Chair of the UKMAS Steering Committee. He is a member of the Advisory Boards of FIPA (the agent standards body), MAAMAW (the European agent conference) and CEEMAS (the Central and Eastern European agent conference). He has served on numerous programme committees for agent conferences and workshops, and has organised and chaired several international conferences in the area of agents, including those for industry. Dr Luck has contributed to policy making forums for national and European agencies, has reviewed proposals for many national and international funding agencies, and has published extensively in this area (with over 75 papers and 5 books). Since 2000, he has been Director of AgentLink, the European Network of Excellence for Agent-Based Computing.

From the reviews of the second edition: An excellent book that lays out a clear conceptual framework for studying and analysing agent-based systems. Nick Jennings Mark d'Inverno and Michael Luck have, over the last six or seven years, been at the forefront of European research in agent systems. This book poses some important foundational questions about agents and their interactions in multi-agent systems and answers them in a coherent and convincing way. It's an extremely valuable contribution to the field. Michael Georgeff It is undoubtedly a clear and most comprehensive attempt to describe agent-based systems in a unified manner. Simon Parsons "This book presents a formal approach to dealing with agents and agent systems. ... The methodology presented takes a very significant step towards organising and structuring the diverse and disparate landscape of agent-based systems by applying formal methods to develop a defining and encompassing agent framework. The book will appeal equally to researchers, students, and professionals in industry." (PHINEWS, Vol. 7, 2005) "The book consists of twelve chapters on two-hundred forty pages and contains a representative list of nearly two hundred references. Each chapter ends with a summary briefly outlining the main ideas. The significant ideas are illustrated by well chosen examples. ... The book is useful for everybody interested in agent-based systems ... . For his/her benefit, he/she gets didactically a perfect book presenting a unified view of a heterogeneous field of agent-based systems." (Tomas Brandejsky, Neural Network World, Vol. 14 (5), 2004)
