说明：  EDA经典算法PBIL程序，与大家分，共同进步(PBIL algorithm EDA classical procedures, and that we can progress together)

Hopfield网络解决旅行商问题（TSP），迭代过程中采用保优方法，并计算最优解和次优解的个数。(Hopfield network Traveling Salesman Problem (TSP), iterative process used method for ensuring quality, and calculating the optimal solution and sub-optimal number of solutions.)

基于灰度图像的目标物的提取、边缘检测、迭代收缩(Extract target grayscale images based on edge detection, iterative shrinkage)

This is the error backpropagation algorithm based character recognition program developed in matlab. The program folder contains the training images of some english alphabets & numerals. & trains the neural network using train command in matlab. The neural network is initialized using newff command. After the simulation, the program recognizes the input character. Accuracy on the provided images is 100 .

该代码能够实现改进的线性调频Z变换的功能，取代FFT变换能够起到细化频谱的作用。(The code can achieve improved chirp Z transform function, replace the FFT spectrum can play a role in refinement.)
