Animals who live in groups need to divide available resources amongst themselves. This is often achieved by means of a dominance hierarchy, where dominant individuals obtain a larger share of the resources than subordinate individuals. This paper introduces a model of dominance hierarchy formation using a multi-player extension of the classical Hawk-Dove game. Animals play non-independent pairwise games in a Swiss tournament which pairs opponents against those which have performed equally well in the conflict so far, for a fixed number of rounds. Resources are divided according to the number of contests won. The model, and its emergent properties, are discussed in the context of experimental observations.
群居动物需要在彼此之间分配可用资源。这通常通过优势等级制度来实现，即优势个体比从属个体获得更大份额的资源。本文引入了一个优势等级制度形成的模型，该模型使用经典鹰鸽博弈的多人扩展。动物们在瑞士制比赛中进行非独立的两两博弈，在固定轮次内，对手会与在冲突中表现同样出色的对手配对。资源根据赢得的比赛次数进行分配。本文在实验观察的背景下讨论了该模型及其涌现特性。
