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 …

supporting her as a junior professor for Computational Social Choice and by the project …

In hedonic games, a set of n agents, having preferences over all possible coalition
structures, needs to agree on a stable outcome. In this work, we initiate the study of hedonic …

We study the formation of stable outcomes via simple dynamics in cardinal hedonic games,
where the utilities of agents change over time depending on the history of the coalition …

We study strategic games inspired by Schelling's seminal model of residential segregation.
These games are played on undirected graphs, with the set of agents partitioned into …

We consider a setting where one has to organize one or several group activities for a set of
agents. Each agent will participate in at most one activity, and her preferences over activities …

We introduce a class of strategic games in which agents are assigned to nodes of a topology
graph and the utility of an agent depends on both the agent's inherent utilities for other …

Hedonic games provide a natural model of coalition formation among self-interested agents.
The associated problem of finding stable outcomes in such games has been extensively …

Coalition formation is concerned with the question of how to partition a set of agents into
disjoint coalitions according to their preferences. Deviating from most of the previous work …

Federated learning (FL) provides a privacy-preserving approach for collaborative training of
machine learning models. Given the potential data heterogeneity, it is crucial to select …
