块图中均衡着色问题的图论与算法方面

Graph theoretic and algorithmic aspect of the equitable coloring problem in block graphs

Hanna Furmańczyk, Vahan Mkrtchyan

AI总结:

本文研究块图中的均衡着色问题,通过建立关联各参数的图论结果,探讨了该问题的固定参数可处理性等算法影响。

摘要:

图$G=(V,E)$的均衡着色是$G$的一种(正常)顶点着色,使得任意两个颜色类的大小相差至多1。本文考虑块图中的均衡着色问题。回顾后者,即每个2-连通分量均为完全图的图。该问题在块图类中仍然是困难的。本文给出了一些关联各参数的图论结果,并利用它们探讨算法方面的影响,主要涉及该问题的固定参数可处理性。

英文摘要:

An equitable coloring of a graph $G=(V,E)$ is a (proper) vertex-coloring of $G$, such that the sizes of any two color classes differ by at most one. In this paper, we consider the equitable coloring problem in block graphs. Recall that the latter are graphs in which each 2-connected component is a complete graph. The problem remains hard in the class of block graphs. In this paper, we present some graph theoretic results relating various parameters. Then we use them in order to trace some algorithmic implications, mainly dealing with the fixed-parameter tractability of the problem.
