Lingo0 1 integer programming, if the constraint condition shows that the variable is a range of values, how to write the code and how to calculate it?
min = a 1 * x 1+a2 * x2+a3 * x3；
n 1 * x 1+N2 * x2+n3 * x3 & gt； =5320;
n 1 * x 1+N2 * x2+n3 * x3 & lt； =5600;
n 1 & gt； = 2 * z 1；
n 1 & lt； = 5 * z 1；
Don't write the back, and so on.
