Altruistic Hedonic Games

Hedonic games are coalition formation in which players have preferences over the coalitions they can join. For a long time, all models of representing hedonic were based upon selfish only. Among known ways compactly, we focus on friend-oriented and propose novel model for them that takes into account not only players’ own but also their friends’ preferences. Depending order look at or preferences, distinguish three degrees altruism: selfish-first, equal-treatment, altruistic-treatment We study both axiomatic properties these computational complexity problems related to various common stability concepts.
