In this text, we first do some research on the genetic algorithm about clustering, discuss about the way of coding and the construction of fitness function, analyze the influence that different genetic manipulation do to the effect of cluster algorithm. then analyze and research on the way that select the initial value in the k - means algorithm, we propose a mix clustering algorithm to improve the k - means algorithm by using genetic algorithm. first we use k - learning genetic algorithm to identify the number of the clusters, then use the clustering result of the genetic clustering algorithm as the initial cluster center of k - means clustering. these two steps are finished based on small database which equably sampling from the whole database, now we have known the number of the clusters and initial cluster center, finally we use k - means algorithm to finish the clustering on the whole database. because genetic algorithm search for the best solution by simulating the process of evolution, the most distinct trait of the algorithm is connotative parallelism and the ability to take advantage of the global information, so the algorithm take on strong steadiness, avoid getting into the local
本文首先對聚類分析的遺傳演算法進行了研究,討論了聚類問題的編碼方式和適應度函數的構造方案與計算方法,分析了不同遺傳操作對聚類演算法的性能和聚類效果的影響意義。然後對k - means演算法中初值的選取方法進行了分析和研究,提出了一種基於遺傳演算法的k - means聚類改進(混合聚類演算法) ,在基於均勻采樣的小樣本集上用k值學習遺傳演算法確定聚類數k ,用遺傳聚類演算法的聚類結果作為k - means聚類的初始聚類中心,最後在已知初始聚類數和初始聚類中心的情況下用k - means演算法對完整數據集進行聚類。由於遺傳演算法是一種通過模擬自然進化過程搜索最優解的方法,其顯著特點是隱含并行性和對全局信息的有效利用的能力,所以新的改進演算法具有較強的穩健性,可避免陷入局部最優,大大提高聚類效果。Before the connectting between moden and other equipments, it works at the cammand mode, the cammand that is send to moden is used to set or manipulate the mode, after the connectting between moden and other equipments, it works at connectting mode, at that time, the cammand send from the computer is send to another computer which will pass the moden and telephone line. the moden control cammand is called " at " cammand, all the control manipulation is realized by sending the ascii character to moden, after the moden received the " at " cammand, it firstly judges the cammand, secondly, it analyses and executes the cammand, finnally, it executes a response by sending back a ascii character, during the deseign of below - computer, we introduce in detail the deseign of system hardware and system software, below - computer system hardware and system software, below - computer is made up of microchip collecting and controlling system, which finish the strobe and water level data collection, display and disposal, deal with the communication with the above - computer, the microchip is the centre of data dealing with, the peripheral equipments are made up of data collecttion module, control cammand input module, display module, execute output module, and long - distance communication module
在moden控制軟體的設計中,詳細敘述了moden正常工作時的幾個重要函數:初始化函數、撥號處理函數、應答處理函數、掛機處理函數,設計並調試了四個函數的通信程序,數據機工作時存在兩種模式,命令模式與連線模式,命令模式是針對功能設置的模式,連線模式是數據傳輸的模式。當數據機未與其他設備連接時,其處于命令模式,這時候下達給數據機的指令是作為數據機本身設置或操作用的;當數據機已經與其他設備連接時,其處于連線模式,所有在此時由計算機送至數據機的信息都將經由電話線傳送到另一部計算機上。專門使用於控制數據機的指令集被稱為「 at指令集」 ,對moden的所有操作(如撥號、應答、掛機等)都可以通過給moden發送ascii字元串來實現, moden在收到at命令后,先對命令進行判斷,接著分析和執行命令緩沖區中的命令,最後以自身的ascii字元對命令作出響應。The major achievements are listed as the followings : mathieu functions remain difficult to employ, mainly because of the impossibility of analytically representing them in a simple and handy way. the methods for the computation of all mathieu functions of integer orders for large range of the order n and the parameter q were presented here. the calculations were made by programs using matlab to compute the mathieu functions
