说明：  图着色局部搜索,图着色问题（Graph Coloring Problem, GCP） 又称着色问题，是最著名的NP-完全问题之一。道路着色问题（Road Coloring Problem）是图论中最著名的猜想之一。 数学定义：给定一个无向图G=（V, E），其中V为顶点集合，E为边集合，图着色问题即为将V分为K个颜色组，每个组形成一个独立集，即其中没有相邻的顶点。其优化版本是希望获得最小的K值。(Graph Coloring Problem (Graph Coloring Problem, GCP), also known as coloring problem, is one of the most famous NP-complete problems. The Road Coloring Problem is one of the most famous conjectures in graph theory. Mathematical definition: Given an undirected graph G=(V, E), where V is the set of vertices and E is the set of edges, the graph coloring problem is to divide V into K color groups, and each group forms an independent set. That is, there are no adjacent vertices. The optimized version is to get the smallest K value.)
