Programming Multi-Agent Systems: Second International Workshop ProMAS 2004, New York, NY, July 20, 2004, Selected Revised and Invited Papers (Lecture Notes in Computer Science, 3346) by Rafael H. Bordini

These are the proceedings of the 2nd International Workshop on Programming Multi-agentSystems(ProMAS2004),heldinJuly2004inNewYork(USA)asan associated event of AAMAS 2004, the main international conference dedicated to autonomous agents and multi-agent systems. The idea of organizing such an event was discussed during the Dagstuhl s- inarProgramming Multi-agent Systems Based on Logic (see [2]), where the focus was on logic-based approaches. It was felt that the scope should be broadened beyond logic-based approaches, and thus ProMAS came into being (see [1] for the proceedings of the ?rst event, ProMAS 2003). Meanwhile, a Steering Committee (Rafael Bordini, Mehdi Dastani, Jurgen ¨ Dix, Amal El Fallah Seghrouchni) as well as an AgentLink III Technical Forum GrouponProgrammingMulti-agentSystems wereestablished(thelatteronewas founded on 30 June/1 July 2004 in Rome, Italy (see www.cs.uu.nl/ mehdi/al3tf8.html). Moreover, a Kluwer book on the same topic is underway (to appear early in 2005) and the third workshop ProMAS 2005 will be organized within AAMAS 2005 (see for up-to-date information about ProMAS).
