摘要

我们将边着色游戏和非对称图着色游戏的思想结合起来,定义了(m,1)边着色游戏,该游戏由两个玩家Maker和Breaker在一个具有一组颜色x的有限简单图G上交替进行。Maker先玩,每回合上色m条无颜色的边。破坏者每回合只上色一条未上色的边。它们确保相邻的边有不同的颜色。如果最终每条边都有颜色,创客就赢了;如果在某一时刻,正在玩游戏的玩家不能给任何边缘上色,则破局者获胜。我们定义G的(m,1)博弈色指数为最小的非负整数k,使得Maker具有|X|=k的制胜策略。我们给出了树的(m,1)-博弈色指标的一般上界,确定了某些毛虫和所有轮子的(m,1)-博弈色指标,并证明了较大的m并不一定给出较小的(m,1)-博弈色指标。

A biased edge coloring game
We combine the ideas of edge coloring games and asymmetric graph coloring games and define the (m,1)-edge coloring game, which is alternatively played by two players Maker and Breaker on a finite simple graph G with a set of colors X. Maker plays first and colors m uncolored edges on each turn. Breaker colors only one uncolored edge on each turn. They make sure that adjacent edges get distinct colors. Maker wins if eventually every edge is colored; Breaker wins if at some point, the player who is playing cannot color any edge. We define the (m,1)-game chromatic index of G to be the smallest nonnegative integer k such that Maker has a winning strategy with |X|=k. We give some general upper bounds on the (m,1)-game chromatic indices of trees, determine the exact (m,1)-game chromatic indices of some caterpillars and all wheels, and show that larger m does not necessarily give us smaller (m,1)-game chromatic index.

期刊介绍: The aim of Discrete Applied Mathematics is to bring together research papers in different areas of algorithmic and applicable discrete mathematics as well as applications of combinatorial mathematics to informatics and various areas of science and technology. Contributions presented to the journal can be research papers, short notes, surveys, and possibly research problems. The "Communications" section will be devoted to the fastest possible publication of recent research results that are checked and recommended for publication by a member of the Editorial Board. The journal will also publish a limited number of book announcements as well as proceedings of conferences. These proceedings will be fully refereed and adhere to the normal standards of the journal. Potential authors are advised to view the journal and the open calls-for-papers of special issues before submitting their manuscripts. Only high-quality, original work that is within the scope of the journal or the targeted special issue will be considered.
