Lagrangian multiplier method

将pso算法与BP神经网络结合，忘对大家有帮助(combine PSO algorithm with BP neural network)

说明：  扩展卡尔曼滤波算法，经过测试可以使用，matlab程序(Extended Kalman filter algorithm)

非常有用的遗传算法程序，包含主程序和子程序，用matlab编写，适合学习和改编，里面有详细的注释。(Very useful genetic algorithm program, including the main program and subprograms, written matlab, suitable for learning and adaptation, there are detailed notes.)

说明：  software engg notes for students

瑞利信道的仿真，里面有瑞利的文档知识，仿真最后出瑞利分布的概率分布密度图和多普勒滤波器的频响图(Rayleigh channel simulation, which has knowledge of the Rayleigh documentation, simulation finally the probability distribution of the Rayleigh distribution density map and Doppler filter response chart)

这是一个标准的Elman的程序外加一个利pso算法优化Elman神经网络权值的程序，可以运行出图，简单易懂！(This is a standard procedure plus a profit Elman pso algorithm to optimize Elman neural network weights program, you can run out of maps, easy to understand!)

这是我最近学习的程序，我希望在这儿能多查找点学习内容，请大家多支持！(which I have recently learning process, I hope it can find learn more, please supported!)

psk and pam modulation and demodulation with noise

说明：  matlab中的Rayleigh信道模型，基于基于Clarke模型的Jakes仿真器(Rayleigh channel model in MATLAB, Jakes simulator based on Clarke model)

使用push-relabel方法求解最大流问题，是国外的一个研究机构编写的，速度很快。(This is an efficient implementation of the push-relabel method. See Goldberg and Tarjan, "A New Approach to the Maximum Flow Problem," J. ACM Vol. 35, 921--940, 1988 and Cherkassky and Goldberg, "On Implementing Push-Relabel Method for the Maximum Flow Problem," Proc. IPCO-4, 157--171, 1995.)
