Coalition formation under uncertainty
2007
Proceedings of the 6th international joint conference on Autonomous agents and multiagent systems - AAMAS '07
Preserved Fulltext
Coalition formation is a problem of great interest in AI, allowing groups of autonomous, rational agents to form stable teams. ...
However, research to date in both AI and economics has largely ignored the potential presence of uncertainty when studying either coalitional stability or coalitional bargaining. ...
Coalition formation can be abstracted into a fairly simple model assuming transferable utility, or the existence of a (divisible) commodity (e.g., money) that players can freely transfer among themselves ...

In contrast, we demonstrate that in games with coalition structures allowing beliefs increases the computational complexity of stability-related problems. ...
We put forward a model to capture such agent-type uncertainty, and study coalitional stability in this setting. ...
In contrast, in non-transferable utility games (NTU games), the worth of a coalition C, |C| = k, is described by a vector of length k, which, for each player i ∈ C, describes the utility that i derives ...

Coalition formation is a central problem in multiagent systems research, but most models assume common knowledge of agent types. ...
In this paper, we propose a novel Bayesian, model-based reinforcement learning framework for this problem, assuming that coalitions are formed (and tasks undertaken) repeatedly. ...
When transferable utility is not assumed, we lie in the realm of non-transferable utility (NTU) games [38] . We do not deal with NTU games in this work. ...

This paper studies coalition formation among selfinterested agents that cannot make sidepayments. ...
We show that -core stability reduces to analyzing whether some utility pro le is maximal for all agents. We also show that the -core is a subset of strong Nash equilibria. ...
It shows, among other results, that stability of the coalition formation process is formally equivalent to convergence of the agents' beliefs (for both exogenously and endogenously terminated negotiation ...

Transferable Utility Games (TU games) In the following, we use a utility-based approach and we assume that "everything has a price": each agent has a utility function that is expressed in currency units ...
