Nguyen et al. (2016) introduced altruistic hedonic games in which agents’ utilities depend not only on their own preferences but also on those of their friends in the same coalition. We propose to extend their model to coalition formation games in general, considering also the friends in other coalitions. Comparing our model to altruistic hedonic games, we argue that excluding some friends from the altruistic behavior of an agent is a major disadvantage that comes with the restriction to hedonic games. After introducing our model and showing some desirable properties, we additionally study some common stability notions and provide a computational analysis of the associated verification and existence problems.

阮等人。（2016）引入了利他享乐博弈，其中代理人的效用不仅取决于他们自己的偏好，还取决于同一联盟中朋友的偏好。我们建议将他们的模型扩展到一般的联盟形成博弈，同时也考虑其他联盟中的朋友。将我们的模型与利他享乐游戏进行比较，我们认为将一些朋友排除在代理人的利他行为之外是限制享乐游戏所带来的一个主要缺点。在介绍我们的模型并展示一些理想的属性之后，我们还研究了一些常见的稳定性概念，并提供了相关验证和存在问题的计算分析。
