st
x1+x2+y1>=4
x1+x2+y1+y2>=3
x1+x2+y1+y2+y3>=4
x2+y1+y2+y3+y4>=6
x1+y2+y3+y4+y5>=5
x1+x2+y3+y4+y5>=6
x1+x2+y4+y5>=8
x1+x2+y5>=8
y1+y2+y3+y4+y5
min 100x1+100x2+40y1+40y2+40y3+40y4+40y5
st
x1+x2+y1>=4

你那是lindo语法 不要跟lingo语法混用
min=100*x1+100*x2+40*y1+40*y2+40*y3+40*y4+40*y5;
x1+x2+y1>=4;
x1+x2+y1+y2>=3;
x1+x2+y1+y2+y3>=4;
x2+y1+y2+y3+y4>=6;

x1+x2+y3+y4+y5>=6;
x1+x2+y4+y5>=8;
x1+x2+y5>=8;
y1+y2+y3+y4+y5
min=100*x1+100*x2+40*y1+40*y2+40*y3+40*y4+40*y5;
