Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

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.)
