This book constitutes the proceedings of the 10th German Conference on Multiagent System Technologies held in Trier Germany, in October 2012. In particular, the conference investigated technologies for truly open distributed systemscovering a wide spectrum of approaches from self-organization and autonomous systems to agreement computing.

This book constitutes the proceedings of the 10th German Conference on Multiagent System Technologies held in Trier Germany, in October 2012.The 7 revised full papers presented together with 6 short parers and one invited paper were carefully reviewed and selected from 39 submissions. The paper cover various research topics in intelligent agents and multi-agent-systems. In particular, the conference investigated technologies for truly open distributed systemscovering a wide spectrum of approaches from self-organization and autonomous systems to agreement computing.
