pso程序的源代码
pso程序的源代码-粒子群优化算法源程序
作者:FashionXu
一个pso程序的源代码。在vc.net2003下面通过。
建议:看代码之前,请先弄明白pso是怎么回事。然后请对应着来:程序中用Agent代表一只鸟,PSO代表鸟群。阅读源代码,不要顺着看,先看main(),然后按照出现的东西的顺序,一个一个得来,呵呵,纯粹是建议。(program s source code pso pso program s source code - source code on Particle Swarm Optimization: FashionXu a pso program source code. In vc.net2003 following through. Recommendation: look at the code before you figure out how the matter pso. Then please correspond to: Program using Agent on behalf of a bird, PSO representative of the flock. Read the source code, do not look down, look at the main (), then follow the order of things there, one by one, come, Oh, merely suggestions.)
