This book constitutes the thoroughly refereed
post-workshop proceedings of the 4th International Workshop on Environments for
Multiagent Systems, E4MAS 2014 - 10 years later, held in Paris, France, in May
2014 as an associated event of AAMAS 2014, the 13th International Conference on
Autonomous Agents and Multiagent Systems.



The 6 revised full papers presented together with 1
roadmap paper and 7 invited papers were carefully reviewed and selected from 14
initial submissions. The papers are organized in topical sections on connecting
agents, environments, and humans; environments for complex and stigmergic
systems; virtual and simulated environments; and open agent environments and
interoperability.
