随机超图上的Maker-Breaker对策

Maker-Breaker Games on Random Hypergraphs

Maxime Larcher

摘要:

本文研究了随机超图$H_{n,s,p}$上的Maker-Breaker对策,该超图是由完全$s$ -图通过保持每条边以概率$p$独立而得到的.我们确定了Maker赢得游戏的阈值概率作为$s$的函数,底层超图的一致性,以及$m$,$b$,Maker和Breaker分别允许挑选每轮的顶点数。另外,我们证明了依赖于这些$m,b,s$,有两种类型的阈值:要么是Maker-win是局部性质,阈值是弱的,要么是与随机超图的全局性质有关,阈值是半尖锐的.我们推测,在后一种情况下,阈值实际上是尖锐的。

英文摘要:

In this paper, we study Maker-Breaker games on the random hypergraph $H_{n,s,p}$, obtained from the complete $s$-graph by keeping every edge independently with probability $p$. We determine the threshold probability for the property of Maker winning the game as a function of $s$, the uniformity of the underlying hypergraph, as well as $m$, $b$, the number of vertices that Maker and Breaker are respectively allowed to pick each turn. In addition, we show that depending on those $m,b,s$, there are two types of thresholds: either being Maker-win is a local property and the threshold is weak, or it is related to global properties of the random hypergraph and the threshold is semi-sharp. We conjecture that in the latter case, the threshold is actually sharp.
