Hamming距离图的鲁棒染色

On Robust Colorings of Hamming-Distance Graphs

Isaiah Harney, Heide Gluesing-Luerssen

摘要:

定义$H_q(n,d)$为顶点集为${\mathbb Z}_q^n$且两个顶点的汉明距离至少为$d$的图.这些图的色数的各种参数$(q,n,d)$。对于图$H_2(n,n-1)$的$4$ -着色,引入了鲁棒性的概念.它是基于沿边交换颜色而不破坏着色适当性的公差。给出了$H_2(n,n-1)$的最大鲁棒$4$ -着色的显式描述.

英文摘要:

$H_q(n,d)$ is defined as the graph with vertex set ${\mathbb Z}_q^n$ and where two vertices are adjacent if their Hamming distance is at least $d$. The chromatic number of these graphs is presented for various sets of parameters $(q,n,d)$. For the $4$-colorings of the graphs $H_2(n,n-1)$ a notion of robustness is introduced. It is based on the tolerance of swapping colors along an edge without destroying properness of the coloring. An explicit description of the maximally robust $4$-colorings of $H_2(n,n-1)$ is presented.
