规模不变的动态垄断

Dynamic monopolies of constant size

Eli Berger

摘要:

本文研究了图上的投票对策问题。最初,每个顶点都是白色或黑色。在每一轮中,每个顶点都由其邻域中的大多数顶点共享的颜色着色。我们说一个顶点集是一个动态垄断,如果开始游戏时顶点集的颜色是白色的,在有限轮之后整个系统都是白色的。法勒提出了一个问题,即动态垄断作为顶点数量的函数可能有多小。我们证明答案是O(1)。

英文摘要:

The paper deals with a polling game on a graph. Initially, each vertex is colored white or black. At each round, each vertex is colored by the color shared by the majority of vertices in its neighborhood. We say that a set of vertices is a dynamic monopoly if starting the game with the vertices of the set colored white, the entire system is white after a finite number of rounds. Peleg asked how small a dynamic monopoly may be as a function of the number of vertices. We show that the answer is O(1).
