我们从计算和历史的角度继续调查a . B. Kempe对四色定理的有缺陷的证明。Kempe的“证明”产生了一种平面图着色的算法方法,有时会产生需要四种或更少颜色的适当顶点着色。我们研究了肯普方法的递归版本和基于I. Kittell工作的修改版本。然后,我们实证分析了实现在各种历史动机基准图上的性能,并探讨了简单随机化在四色小平面图中的有用性。最后,我们列出了一系列悬而未决的问题和未来的工作。
We continue the investigation of A. B. Kempe’s flawed proof of the Four Color Theorem from a computational and historical point of view. Kempe’s “proof” gives rise to an algorithmic method of coloring plane graphs that sometimes yields a proper vertex coloring requiring four or fewer colors. We investigate a recursive version of Kempe’s method and a modified version based on the work of I. Kittell. Then we empirically analyze the performance of the implementations on a variety of historically motivated benchmark graphs and explore the usefulness of simple randomization in four-coloring small plane graphs. We end with a list of open questions and future work.
