在线单位区间着色Kierstead-Trotter算法的严密分析

A tight analysis of Kierstead-Trotter algorithm for online unit interval coloring

Tetsuya Araki, Koji M. Kobayashi

摘要:

Kierstead和Trotter(Congressus Numerantium 33,1981)证明了他们的算法是在线区间着色问题的最优在线算法。本文证明了在线单位区间着色的Kierstead-Trotter算法所使用的颜色数至多为$3 ω(G) - 3$,其中$ω(G)$是给定图$G$中最大团的大小,并且它是最佳可能的.

英文摘要:

Kierstead and Trotter (Congressus Numerantium 33, 1981) proved that their algorithm is an optimal online algorithm for the online interval coloring problem. In this paper, for online unit interval coloring, we show that the number of colors used by the Kierstead-Trotter algorithm is at most $3 ω(G) - 3$, where $ω(G)$ is the size of the maximum clique in a given graph $G$, and it is the best possible.
