On two $q$-ary $n$-cube coloring problems
Abstract
Let $χ'_d(n,q)$ (resp. $χ_d(n,q)$) denote the minimum number of colors necessary to color a $q$-ary $n$-cube so that no two vertices that are at a distance at most $d$ (resp. exactly $d$) get the same color. These two problems were proposed in the study of scalability of optical networks. In this paper, we provide upper and lower bounds on $χ'_d(n,q)$ and $χ_d(n,q)$ when $q$ is a prime power.
