CoopMAS 2013 - The Fourth Workshop on Cooperative Games in Multiagent Systems (CoopMAS 2013)

The use of cooperative game theory to study how agents should cooperate and collaborate, along with the related topic of coalition formation, has received growing attention from the multiagent systems, game theory, and electronic commerce communities.
The workshop is intended to focus on topics in cooperation in multi-agent systems, cooperative game theory and cooperative solution concepts, formation of coalitions, negotiation between agents, joint decision making, and voting. Topics of interest include, but are not limited to:
Cooperative game theory
Coalition formation
Joint decision making and voting
Representation issues
Negotiation
Collaborative filtering
Market and economics based cooperation
Interact with humans (negotiation / collaboration)
The workshop should be of interest to researchers in cooperative game theory and coalition formation, as well as to those who examine collaboration between agents, cooperation in multiagent systems and design and implement collaborating agents. We also welcome participants who are interested in applications of cooperative game theory, which include trading agents, sponsored search and recommender systems.
