Hi everyone I have 3 set A /45*200/ ,B/39*443/ ,and c/12*187/. I show symmetric difference of A,B by symAB, symmetric difference of A,c by symAc and symmetric difference of B,c by symBc, I want to code below summation in GAMS Sum(k$ k isn't belong to symAB)+Sum(k$ k isn't belong to symAc) <= Sum(j$ ...
