Question

帮我检查一下这个lingo程序的问题,编译的时候总是说date有问题
非常感谢
model:
sets:
quantity/1..10/:x,y;

endsets
min =@sum(quantity:(1/(((2*3.14159)^0.5)*a))*@exp(-(x-b)^2/2*a^2)-y/159*20)^2;
@free(a);
@free(b);

date:
x=100 120 140 160 180 200 220 240 260 280;
y=3 9 13 22 32 35 20 15 8 2;
enddate
end

Answer 1

data写错了
model:
sets:
quantity/1..10/:x,y;

endsets
min =@sum(quantity:(1/(((2*3.14159)^0.5)*a))*@exp(-(x-b)^2/2*a^2)-y/159*20)^2;
@free(a);
@free(b);

data:
x=100 120 140 160 180 200 220 240 260 280;
y=3 9 13 22 32 35 20 15 8 2;
enddata
end
