智能多媒體實(shí)驗(yàn)報(bào)告基于遺傳算法的函數(shù)優(yōu)化

1、智能多媒體實(shí)驗(yàn)報(bào)告實(shí)驗(yàn)六：基于遺傳算法的函數(shù)優(yōu)化姓名：班級(jí)：學(xué)號(hào)：同做者： 一、實(shí)驗(yàn)?zāi)康睦眠z傳算法求解函數(shù)極值。二、算法概要1遺傳算法概要遺傳算法是具有“生成+檢測(cè)”的迭代過(guò)程的搜索算法。它的基本處理流程如圖6.1所示。由此流程圖可見(jiàn)，遺傳算法是一種群體型操作，該操作以群體中的所有個(gè)體為對(duì)象。選擇（selection）、交叉（crossover）和變異（mutation）是遺傳算法的3個(gè)主要操作算子，它們構(gòu)成了所謂的遺傳操作（genetic operation），使遺傳算法具有了其它傳統(tǒng)方法所沒(méi)有的特性。遺傳算子包含如下6個(gè)基本因素：（1） 參數(shù)編碼：由于遺傳算法不能直接處理解空間的解數(shù)據(jù)，

2、因此必須通過(guò)編碼將它們表示成遺傳空間的基因型串結(jié)構(gòu)數(shù)據(jù)。（2） 生成初始群體：由于遺傳算法的群體型操作需要，所以必須為遺傳操作準(zhǔn)備一個(gè)由若干初始解組成的初始群體。初始群體的每個(gè)個(gè)體都是通過(guò)隨機(jī)方法產(chǎn)生。（3） 適應(yīng)度評(píng)估檢測(cè)：遺傳算法在搜索進(jìn)化過(guò)程中一般不需要其他外部信息，僅用適應(yīng)度（fitness）值來(lái)評(píng)估個(gè)體或解的優(yōu)劣，并作為以后遺傳操作的依據(jù)。（4） 選擇（selection）：選擇或復(fù)制操作是為了從當(dāng)前群體中選出優(yōu)良的個(gè)體， 使它們有機(jī)會(huì)作為父代為下一代繁殖子孫。個(gè)體適應(yīng)度越高，其被選擇的機(jī)會(huì)就越多。此處采用與適用度成比例的概率方法進(jìn)行選擇。具體地說(shuō)，就是首先計(jì)算群體中所有個(gè)體適應(yīng)度的

3、總和（），再計(jì)算每個(gè)個(gè)體的適應(yīng)度所占的比例（），并以此作為相應(yīng)的選擇概率。（5） 交叉操作：交叉操作是遺傳算法中最主要的遺傳操作。簡(jiǎn)單的交叉（即一點(diǎn)交叉）可分兩步進(jìn)行：首先對(duì)種群中個(gè)體進(jìn)行隨機(jī)配對(duì);其次，在配對(duì)個(gè)體中隨機(jī)設(shè)定交叉處，配對(duì)個(gè)體彼此交換部分信息。（6） 變異：變異操作是按位（bit）進(jìn)行的，即把某一位的內(nèi)容進(jìn)行變異。變異操作同樣也是隨機(jī)進(jìn)行的。一般而言，變異概率都取得較小。變異操作是十分微妙的遺傳操作，它需要和交叉操作配合使用，目的是挖掘群體中個(gè)體的多樣性，克服有可能限于局部解的弊病。這6個(gè)要素構(gòu)成了遺傳算法的核心內(nèi)容，其流程如圖6.1所示。圖6.1 遺傳算法的基本流程2二進(jìn)制編碼

4、及解碼方法二進(jìn)制編碼是遺傳算法中最主要的一種編碼方法，它使用的編碼符號(hào)集是由二進(jìn)制符號(hào)0和1所組成的二進(jìn)制符號(hào)集0，1，它所構(gòu)成的個(gè)體基因型是一個(gè)二進(jìn)制編碼符號(hào)串。二進(jìn)制編碼符號(hào)串的長(zhǎng)度與問(wèn)題所要求的求解精度有關(guān)。假設(shè)某一參數(shù)的取值范圍是umin，umax，我們用長(zhǎng)度為l的二進(jìn)制編碼符號(hào)串來(lái)表示該參數(shù)，則它總共能夠產(chǎn)生種不同的編碼，若使參數(shù)編碼時(shí)的對(duì)應(yīng)關(guān)系如下：0000000000000000=0 umin 0000000000000001=1 umin+ 11111111111111111=2l1 umax則二進(jìn)制編碼的編碼精度為： （6-1）假設(shè)某一個(gè)個(gè)體的編碼是：x blbl1bl，則對(duì)

5、應(yīng)的解碼公式為： （6-2）例如，對(duì)于，若用十位長(zhǎng)的二進(jìn)制編碼來(lái)表示該參數(shù)的話，則下述符號(hào)串：x：0010101111就可表示一個(gè)個(gè)體，它所對(duì)應(yīng)的參數(shù)值是。此時(shí)的編碼精度為。其中：f 個(gè)體適應(yīng)度umin，umax 某變量的取值范圍 編碼精度三、算法步驟及流程圖step1：參數(shù)設(shè)置及種群初始化；step2：適應(yīng)度評(píng)價(jià)；step3：輪盤賭選擇；step4：交叉；step5：變異；step6：適應(yīng)度評(píng)價(jià)；step7：終止條件判斷，若未達(dá)到終止條件，則轉(zhuǎn)到step3；step8：輸出結(jié)果。四、實(shí)驗(yàn)程序主程序clc;clear;close all;v = 2*rand(50,22)-1;v=hardli
