%?主函數(shù)，用遺傳算法解決雙目標(biāo)優(yōu)化問題
%?Sun?Qifeng?2010、4、26
%?=====================目標(biāo)函數(shù)======================
%?min?f1=300/x+500/y+300/（100-x-y）
%?min?f2=30（300/x-3）+12（500/y-5）+（300/（100-x-y）-3）????
%?======================約束=========================
%?x、y為正整數(shù)，且x+y<100
%?======================調(diào)用函數(shù)說明=================
%?inipop.m????生成初始種群
%?Pareto.m????把種群中的pareto解保存到popbest中
%?crossover.m?交叉操作
%?mutation.m??變異操作
%?decoding.m??解碼操作
%?elimination.m?將popbest中的非pareto解去掉
%?selection.m?選擇操作

popsize=100;%種群規(guī)模
Maxgen=100;%最大迭代次數(shù)
pm=0.15;%變異概率
pc=0.8;%交叉概率
L=14;%?100的二進(jìn)制為1100100，所以由x、y構(gòu)成的染色體長度為14。
