Hi, I have a decision variable defined as
x(i,j,k,t) where i in I j in J(i) k in K(i,j) That is, the number of elements of J depends on the "i". For instance, J(1) has 1 element, J(2) has 1 element, J(3) has 4 elements, J(4) has 6 elements and so on. Is it possible to use GMPL to define this variable? Thanks for the help, Antonio _______________________________________________ Help-glpk mailing list Help-glpk@gnu.org https://lists.gnu.org/mailman/listinfo/help-glpk
