The Journal will publish original, high quality papers on the theory and practice of autonomous agents and multi-agent systems. While a range of submissions are welcome, from purely theoretical to application-oriented, all submissions should indicate both the consequences of their results for the development of agent systems and the significance of their results for other researchers and practitioners within the field. The Journal will be multi-disciplinary, in that it will be relevant to many fields that share interests with agent systems. These fields include computer science and artificial intelligence, software engineering, distributed systems, distributed artificial intelligence, computer-supported cooperative work, knowledge representation and manipulation, ethology, psychology, organizational theory, sociology, linguistics, philosophy, economics, and cognitive science.
