lingo 0-1规划问题
model:

number/1..56/;
assign(class,number):c,x;
endsets
data:
c = 41,45,44,44,26,44,42,20,20,38,37,25,45,45,45,44,20,30,39,35,38,38,28,25,30,36,20,24,32,33,41,33,51,39,20,20,44,37,38,39,42,40,37,50,50,42,43,41,42,45,42,19,39,75,17,17;

end
求大神看下哪里错了
lingo 0-1规划问题
c是56*56的矩阵,你给的那点数据明显不够数...
model:
sets:
class/1..56/;
number/1..56/;
assign(class,number):c,x;
endsets
data:
!c = 41,45,44,44,26,44,42,20,20,38,37,25,45,45,45,44,20,30,39,35,38,38,28,25,30,36,20,24,32,33,41,33,51,39,20,20,44,37,38,39,42,40,37,50,50,42,43,41,42,45,42,19,39,75,17,17;
Enddata
max=@sum(assign:c*x);
@for(assign:@bin(x));
end
