粒子群优化最优路径算法，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优(Similar to simulated annealing (SA), particle swarm optimization (PSO) optimizes the optimal path by iteratively searching for the optimal solution from a random solution. It also evaluates the quality of the solution by fitness, but it is simpler than the genetic algorithm rules. It does not have the crossover and Mutation operations of genetic algorithm. It finds the global optimum by following the best values currently searched.)

整理网上matlab环境元胞自动机18个源程序，全部调试通过。对广大matlab用户研究了解元胞机有重要参考价值。(collected cellular automata 18 matlab source, which has an important value of reference for Matlab users.)

MATLAB具有强大的图形处理能力，用于使科学计算的结果可视化；VB是目前广泛使用的Windows鳊 程语言，简单易学，且具有良好的用户界面．通过二者的结合，可太大增强用户自行开发软件的功能。 (MATLAB has powerful graphics capabilities, for making the results of scientific computing visualization VB is widely used Windows bream process language, easy to learn, and has a good user interface. Through the combination of the two can be much enhanced user-developed software.)

matlab数学手册，里面是这本书的word文件和源代码(Matlab mathematics is the book handbook, the word document and the source code)

In this letter, we employ orthogonal random beam-forming (ORBF) for the worst-case multi-user downlink scenario whereeachuseriswiretappedby one eavesdropper. Two oppor-tunistic scheduling techniques that ensure confidentiality by ex-ploiting multi-user diversity are investigated thefirst technique (optimal) requires limited feedback of the effective signal-to-in-terference ratio (SIR) from all the users
