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
