[gecode-users] Sets difference

[Mauricio Toro]

Hello,
I made the difference. There was a bug in other part of the code.
But the problem with the ".." representation is that I am getting
too many solutions representing the same, such as:
(1,2..5)
(1,2,3..5)
(1,2,3,4,5)

and I just want to get (1,2,3,4,5).

What can I do ?

thanks
