The work we present in this article initiated the formal study of fractional hedonic games
(FHGs), coalition formation games in which the utility of a player is the average value he …

We consider fractional hedonic games, a subclass of coalition formation games that can be
succinctly modeled by means of a graph in which nodes represent agents and edge weights …

This paper examines the performance of a number of AI agents on the games included in
the General Video Game Playing Competition. Through analyzing these results, the paper …

In this paper, we propose a natural notion of individual preference (IP) stability for clustering,
which asks that every data point, on average, is closer to the points in its own cluster than to …

In coalition formation games self-organized coalitions are created as a result of the strategic
interactions of independent agents. In this paper we assume that for each couple of agents …

Additively separable hedonic games and fractional hedonic games have received
considerable attention in the literature. They are coalition formation games among selfish …

Game theory has emerged as a brand new approach to model and analyse several
problems of wireless sensor networks, such as routing, data collection, and topology control …

Abstract The Price of Anarchy measures the welfare loss caused by selfish behavior: it is
defined as the ratio of the social welfare in a socially optimal outcome and in a worst Nash …

We introduce natural strategic games on graphs, which capture the idea of coordination in a
local setting. We study the existence of equilibria that are resilient to coalitional deviations of …

Cluster formation games are games in which self-organized groups (or clusters) are created
as a result of the strategic interactions of independent and selfish players. We consider …
