改进版的bp神经网络算法编程 可以正常运行 (An improved version of the bp neural network algorithm to the normal operation of programming)

这是一个人脸识别的matlab例程，可以运行(here is an example of facerecognize)

用matlab实现的遗传算法与BP神经网络的优化算法。(Matlab genetic algorithm with BP neural network to achieve optimization algorithm.)

对于petri网原理与应用相关论文研究(the implication of petri net)

说明：  根据教科书上已经给出的简单的数学算式，运用matlab编写出简单的代码，计算出结果(According to the textbook has been given a simple mathematical formula, using matlab write simple code to calculate the results)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

这是我参加12年美国数学建模大赛，关于Camping along the Big Long Rive这个问题的一些代码，虽然不算很好吧，但是有些结果还是不错的(I attended 12 years of the American Mathematical Modeling Contest, Camping along the Big Long Rive problem code, although it is not very good, but some results are still good)
