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.)

在遥感应用领域，植被指数已广泛用来定性和定量评价植被覆盖及其生长活力。由于植被光谱表现为植被、土壤亮度、环境影响、阴影、土壤颜色和湿度复杂混合反应，而且受大气空间―时相变化的影响，因此植被指数没有一个普遍的值，其研究经常表明不同的结果。-in the field of remote sensing applications, vegetation index has been widely used for the qualitative and quantitative evaluation of the growth of vegetation cover and its vitality. As the spectral performance of the vegetation cover, soil brightness, environmental impact, shadow, color and soil moisture complex mixed reaction and by the atmospheric space-phase change, vegetation index therefore not a universal value, its regular show different results.
