Even though the scientific contributions generated by the Multi-Agent Systems (MAS) research community can have a significant impact in the development of real-world distributed systems, the techniques resulting from such contributions will only be widely adopted when suitable programming languages and tools are available. Furthermore, such languages and tools must incorporate MAS techniques in a principled but practical way, so as to support the ever more complex task of professional programmers, in particular when the systems have to operate in dynamic environments.
The ProMAS workshop series aims to address practical issues related to developing and deploying multi-agent systems. In particular, ProMAS aims to address how MAS designs or specifications can be effectively implemented. To address such issues, the workshop promotes the discussion and exchange of ideas concerning concepts, techniques, and principles that are important for multi-agent programming technology. In the three previous editions, ProMAS constituted an invaluable occasion, bringing together leading researchers from both academia and industry to discuss such issues. Confirming the growing importance of this area of research, in 2005 ProMAS was the most popular of all AAMAS workshops in terms of numbers of registered participants.
