偏向性游戏

Biased orientation games

Ido Ben-Eliezer, Michael Krivelevich, Benny Sudakov

摘要:

我们研究有偏{ \em方向游戏},其中董事会是完整的图$K_n$,和制造商和断路器轮流在指导以前无向边的$K_n$。在游戏结束时,获得的图是一个锦标赛。如果锦标赛有某些属性$\mathcal P$,庄家赢,否则庄家赢。我们提供了在三场不同的比赛中庄家获胜和断路器获胜所需的偏差界限。在第一场比赛中,如果获得的锦标赛有一个循环,则Maker获胜。第二个博弈是Hamilton性,如果所获得的锦标赛包含Hamilton循环,则Maker获胜。最后,我们考虑$H$创建游戏,如果获得的锦标赛有一个固定的图$H$的副本,则Maker获胜。

英文摘要:

We study biased {\em orientation games}, in which the board is the complete graph $K_n$, and Maker and Breaker take turns in directing previously undirected edges of $K_n$. At the end of the game, the obtained graph is a tournament. Maker wins if the tournament has some property $\mathcal P$ and Breaker wins otherwise. We provide bounds on the bias that is required for a Maker's win and for a Breaker's win in three different games. In the first game Maker wins if the obtained tournament has a cycle. The second game is Hamiltonicity, where Maker wins if the obtained tournament contains a Hamilton cycle. Finally, we consider the $H$-creation game, where Maker wins if the obtained tournament has a copy of some fixed graph $H$.
