[gecode-users] Display the values of a set of variable without duplicates

[Christian Schulte]

Hi,

One way to do it is as follows:
 - You create a space s that only has a brancher for x and y
 - You create a search engine e1 for s and find a solution, say s1
 - You post a brancher in s1 for z and k.
 - You create a search engine e2 for s and find just a single solution!
 - You can then also get more solutions from e1 and repeat the previous two
steps.

That should do the trick

Best
Christian
