Beyond Weighted Voting Games

Beyond Weighted Voting Games

Abstract

Weighted voting games are a simple but useful class of coalitional games that can model many real-life settings ranging from political decision-making to multi-agent coordination. However, the traditional model of weighted voting games does not allow for multiple coalitions to form simultaneously, or for agents to be uncertain about each other's weights. In this talk, we discuss extensions of weighted voting games that can handle these issues. Our main focus will be the stability of the resulting coalitions and coalition structures. We will also discuss computational issues that arise in such games.
