Let be an integer and consider the following game on the complete graph for : Two players, Maker and Breaker, alternately claim previously unclaimed edges of such that in each turn Maker claims one and Breaker claims edges. Maker wins if her graph contains a -factor, that is a collection of vertex-disjoint copies of , and Breaker wins otherwise. In other words, we consider a b-biased -factor Maker–Breaker game. We show that the threshold bias for this game is of order . This makes a step towards determining the threshold bias for making bounded-degree spanning graphs and extends a result of Allen et al. who resolved the case up to a logarithmic factor.

集团因素博弈的阈值偏差
让 是一个整数,并在完整图上考虑以下游戏 为了 : Maker 和 Breaker 两个玩家轮流占据之前无人认领的边缘 使得在每一轮中 Maker 声称一个而 Breaker 声称 边缘。如果 Maker 的图表包含一个-factor,这是一个集合 顶点不相交的副本 ,否则 Breaker 获胜。换句话说,我们考虑 a b -biased-factor Maker–Breaker 游戏。我们证明了这个游戏的阈值偏差是有序的. 这朝着确定用于制作有界度跨越图的阈值偏差迈出了一步,并扩展了 Allen 等人的结果。谁解决了这个案子 直到一个对数因子。
