Question

lingo11 error 11指在a=@sum(jingdian(j):@sum(jingdian(i):r(i,j)*(tt(i,j)+0.5*(t(i)+t(j)))));分号后

真的不知道错在哪？
model:
sets:
jingdian/1..15/:c,t,l;
links(jingdian,jingdian):r,cc,tt;
endsets
data:
省略
n=?;
enddata
min=@sum(jingdian(j):@sum(jingdian(i):r(i,j)*(cc(i,j)+0.5*(c(i)+c(j)))));

@for(jingdian(i)|i#gt#1:l(i)<n-1-(n-2)*r(1,i);l(i)>1+(n-2)*r(i,1));
end

Answer 1

要不试试把a=@sum(jingdian(j):@sum(jingdian(i):r(i,j)*(tt(i,j)+0.5*(t(i)+t(j)))));这段放在calc 里面运行。
