我的lingo为什么会弹出inproper use of @for() function
model:
sets:
\x05chandi/A1..A4/:a,p;
\x05xiaodi/B1..B8/:b,q;
\x05links(chandi,xiaodi):c,x;
endsets
these are the data;
data:
\x05a=12 16 16 20;
\x05b=6 5 8 10 6 5 8 6;
\x05p=12 16 16 20;
\x05q=105 110 108 105 110 112 126 132;
\x05c=2 11 3 4 12 16 22 26
\x05 10 3 5 9 15 18 24 35
\x05 7 8 1 2 8 13 33 48
\x05 12 9 16 7 16 21 42 56;
enddata
this is the objective;
max=@sum(xiaodi(j):q(j)*@sum(chandi(i):x(i,j)))-@sum(links:c*x
-@sum(chandi(i):p(i)*@sum(xiaodi(j):x(i,j)));
this is the demand contraints;
@for(xiaodi(j):
\x05@sum(chandi(i):x(i,j))

max 那句少右括号

为什么我进CF的,会弹出 I was a at bit of a loss的字样然后出现XS出错,我重新下载很多次`, 为什么我玩虐杀原形会弹出这个我的这个lingo程序为什么解不出 use a graph to find the zeros of the function lingo运行时出现improper use of set name! Lingo运行出现“Improper use of set name”,怎么修改? 我用Image J 测量显微照片中细胞的直径的时候,为什么我只要选择直线工具划线后,总是会弹出Cut/copy窗口,上面在看格式为mkv的动画时,有时会弹出"list index out of bounds" lingo 编程问题；；积分我会全给的； lingo的for语句问题为什么我开机时会弹出Please wait? 我的跑跑玩不到会弹出 problem has occurred with the hack shield functio
