Hello everyone
I have this constraint:
x(i)+x1(i,j)-x2(j)<=MM*y2(i)
this constraint certify for each i and j=i+1
x(i),x1(i,j) and x2(j) are positive variables.y2(i) is binary variable. MM in a big number
please help me to add it to the constraint.

Hi Neda

If I understand you correctly, you could write



Alias(i,j);

…

x(i)+x1(i,i+1)-x2(i+1)<=MM*y2(i);
