Comment (by coniglio):

 Replying to [comment:1 mjs]:
 > Apologies if you already knew that, but the example you provide doesn't
 contain the necessary bounds.
 No, I didn't know that. Thanks a lot for pointing it out.
 By the way, are you sure AMPL behaves the same? I'm trying it at this very
 moment and it seems it doens't. No matter anyway.

 -x1 - 1 if both variables are free.)
 Uh, yes. It was just an optimal one, sure.

 Thanks again.
