We consider three-sided coalition formation problems when each agent is concerned about his local status as measured by … the average rankings of the other types of groups. We show that a core stable coalition structure always exists, provided …

We consider a hedonic coalition formation game in which at each possible partition any new coalition can decide the … can decide whether or not to support a coalition's move: they know which future partition, and hence payoffs, will be … probabilities that are always above some e > 0, then there is a behavior profile in which no coalition has a profitable one …

coalition is given by the sum of the valuations for all other players belonging to it. So far, non-cooperative hedonic games …

We investigate the computational complexity of several decision problems in hedonic coalition formation games and … either core stability or strict core stability is under consideration, the existence problem of a stable coalition structure … stable coalition structure and of an individually stable coalition structure turn out to be NP-complete in the strong sense …
