Hello, I am a Xpress starter and I need a little help with the command.
Now I want to obtain the size of mpvar(my variables ROUTE). I know Xpress can do that if I define a set of integer.
But here, I create a dynamic array and I generate the variables by "forall(r in NODE, s in NODE|r<>s and location(r)=1 and location(s)=1) create (ROUTE)".
Which command can I use to get the size of ROUTE?
Any answer will be helpful! Thanks in advance!
