基于greedy DSATUR 的经典着色程序(Given a graph, vertex coloring is the assignment of colors to the vertices such that no two adjacents vertices share the same color. Vertex coloring problem is NP-hard for general graphs. However for some specific graph classes there are some positif results. For example by definition we can trivially color a bipartite graph using two colors.)
