lingo里面@for()函数出错,
model:
sets:
row/1,2,3/:b;
arrange/1..5/:x,c;
link(row,arrange):a;
endsets
data:
b=100,100,100;
c=0,0.1,0.2,0.3,0.8;
a=1,2,0,1,0,0,0,2,2,1,3,1,2,0,3;
enddata
[OBJ]min=@sum(arrange(j):c(j)*x(j);
@for(row(i):@sum(arrange(j):a(i,j)*x(j))=b(i););
@for(arrange(j):x(j)>=0;);
end

model:
sets:
row/1,2,3/:b;

endsets
data:
b=100,100,100;
c=0,0.1,0.2,0.3,0.8;
a=1,2,0,1,0,0,0,2,2,1,3,1,2,0,3;
enddata
[OBJ]min=@sum(arrange(j):c(j)*x(j));!这边最后面漏掉一个左括号);
@for(row(i):@sum(arrange(j):a(i,j)*x(j))=b(i););
@for(arrange(j):x(j)>=0;);
end

lingo里面@for()函数出错, lingo for函数出错 lingo for函数错误 lingo中for函数用法? lingo线性规划算法出错! lingo,@for函数莫名报错 lingo中@for函数报错, lingo中@for函数用错 lingo编程出现老出错, lingo模型定义出错问题 Lingo 那里出错了啊? LINGO程序哪里出错了
