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 …

The housing market [24] is one of the most investigated model for multi-agent resource
allocation. In traditional housing markets, each agent is endowed with a single unit of an …

Hedonic games are a well-studied model of coalition formation, in which selfish agents are
partitioned into disjoint sets and agents care about the make-up of the coalition they end up …

Hedonic diversity games are a variant of the classical hedonic games designed to better
model a variety of questions concerning diversity and fairness. Previous works mainly …

We propose a new variant of the group activity selection problem (GASP), where the agents
are placed on a social network and activities can only be assigned to connected subgroups …

We consider a coalition formation setting where each agent belongs to one of the two types,
and agents' preferences over coalitions are determined by the fraction of the agents of their …

Social networks play a central role in the transactions and decision making of individuals by
correlating the behaviors and preferences of connected agents. We introduce a notion of …

We revisit the complexity of the well-studied notion of Additively Separable Hedonic Games
(ASHGs). Such games model a basic clustering or coalition formation scenario in which …

The classical house allocation problem involves assigning $ n $ houses (or items) to $ n $
agents according to their preferences. A key criterion in such problems is satisfying some …
