This book constitutes the thoroughly refereed post-conference proceedings of the 10th International Workshop on Programming Multi-Agents Systems held in Valencia, Spain, in June 2012. The 10 revised full papers presented were carefully selected from 14 submissions covering a wide range of topics in multi-agent system programming languages, including language design and efficient implementation, agent communication, and robot programming. I addition to these regular papers, the volume includes six papers from the Multi-Agent programming Contest 2012 (MAPC).

This book constitutes the thoroughly refereed post-workshop proceedings of the Third International Workshop on Languages, Methodologies, and Development Tools for Multi-Agent Systems, LADS 2010, held in Lyon, France, in August/September 2010, as part of MALLOW, a federation of workshops on Multi-Agent Logics, Languages, and Organizations. The 8 revised full papers presented were carefully selected during two rounds of reviews from 11 initial submissions. The papers address issues related to theories, methodologies, models and approaches that are needed to facilitate the development of multi-agent systems ensuring their predictablity and verification.

Multi-agent systems (MAS) are often understood as complex entities where a multitude of agents interact, usually with some intended individual or collective goals.Such a view usually assumessomeform of organization, or set of norms or conventions that articulate or restrain interactions in order to make them more e?ective, certain, or predictable for participants. Engineering e?ective coordi- tion or regulatory mechanisms is a key problem for the design of open complex multi-agent systems. In recent years, social and organizational aspects of agency have become a major issue in MAS research especially in applications on service-oriented c- puting, grid computing and ambient intelligence. These applications enforce the need for using these aspects in order to ensure social order within these en- ronments. Openness, heterogeneity, and scalability of MAS pose new demands on traditional MAS interaction models. Therefore, the view of coordination and controlhasto be expanded to consider not onlyan agent-centricperspective but also societal and organization-centric views. However, agent autonomy is often needed for concretely implementing social order, because autonomousagents can intelligently adapt the designedorgani- tion to particular cases and can face unpredicted events. From this perspective autonomy can also be a possible source of internal change in the designed or- nizational constructs. Di?erently, autonomous behavior can also originate forms of self-organizationwhich emerge out of local interactions and are only partially externally programmed. In such situations the self-organized order and the - ternally designed organization can even be in con?ic

This book constitutes the thoroughly refereed post-conference proceedings of the 8th International Workshop on Engineering Multi-Agent Systems, EMAS 2020, held in Auckland, New Zealand, in May 2020. Due to the COVID-19 pandemic the conference was held virtually. The 10 revised full papers presented in this book were carefully selected and reviewed from 16 submissions. The papers cover a broad range of topics in the domains of agent-oriented software engineering, programming multi-agent systems, declarative agent languages and technologies, artificial intelligence, and machine learning.
