Question

大虾请进 小弟跪求一个lingo问题 急急急急急急急

model:
sets:
ten/1..10/;
four/1..4/;
score(ten,four):a,x;
endsets
max=@sum(score(i,j):x(i,j)*a(i,j));
@for(four(j):@sum(ten(i):x(i,j))=6);
@for(ten(i):@sum(four(j):x(i,j))=4);
@for(ten(i):(1-@floor((ten(i):@sum(four(j):x(i,j)))*0.25)*(ten(i):@sum(four(j):x(i,j)))<=3);
@for(score:@bin(x));
M=@sum(score(i,j):x(i,j)*a(i,j));
data:
a=8.4 9.3 8.4 8.1 8.4 9.4 9.5 8.4 8.4 9.0
8.4 8.4 8.1 8.7 9.0 8.7 8.4 8.8 8.4 8.1
9.1 8.4 8.4 9.0 8.3 8.5 8.3 8.7 8.4 8.2
8.7 8.9 9.5 8.4 9.4 8.4 8.4 8.2 9.3 9.1;
enddata
end

Answer 1

这样没有语法错误 但是没有可行解 你那个<=3一句到底是什么意思
model:
sets:
ten/1..10/;
four/1..4/;
score(ten,four):a,x;
endsets
max=@sum(score(i,j):x(i,j)*a(i,j));
@for(four(j):@sum(ten(i):x(i,j))=6);
@for(ten(i):@sum(four(j):x(i,j))=4);
@for(ten(i):(1-@floor((@sum(four(j):x(i,j)))*0.25))*@sum(four(j):x(i,j))<=3);
@for(score:@bin(x));
M=@sum(score(i,j):x(i,j)*a(i,j));
data:
a=8.4 9.3 8.4 8.1 8.4 9.4 9.5 8.4 8.4 9.0
8.4 8.4 8.1 8.7 9.0 8.7 8.4 8.8 8.4 8.1
9.1 8.4 8.4 9.0 8.3 8.5 8.3 8.7 8.4 8.2
8.7 8.9 9.5 8.4 9.4 8.4 8.4 8.2 9.3 9.1;
enddata
end
