说明：  利用遗传算法，对一个函数求取极值的一种方法，考虑到普通遗传算法中初始种群，对极值影响较大，程序的采用了多个初试种群同时学习，相互比较以求取极大值。(use of genetic algorithm, a function of a strike extreme methods, taking into account the general genetic algorithm initial population, Extreme right big impact and the procedures used to try various species while learning, in order to obtain comparable value.)

Stop-and-wait ARQ is a method used in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order. It is the simplest kind of automatic repeat-request (ARQ) method. A stop-and-wait ARQ sender sends one frame at a time it is a special case of the general sliding window protocol with both transmit and receive window sizes equal to 1. After sending each frame, the sender doesn t send any further frames until it receives an acknowledgement (ACK) signal. After receiving a good frame, the receiver sends an ACK. If the ACK does not reach the sender before a certain time, known as the timeout, the sender sends the same frame again.

该程序可以用于产生LFM信号，并输出在理想和加噪情况下分别经过匹配滤波器后的结果。(The program can be used to generate LFM signal, and outputs the noise in the ideal case and processing each of the results after the matched filter.)

This Matlab code calculates the Rand Index and Adjusted rand Index between two clustering groups. The two input clusters has to be in the form of a structure as shown in the example mat file ( A and B ) attached in the folder. The code calculates the contingency table among the cluster and then calculates the Rand Index and Adjusted Rand Index. Using the value of the indices one can know about the similarity of the clustering group
