Example: Finding optimal Golomb rulers
The script makes use of two lower bounds taken from: Barbara Smith, Kostas Stergiou, Toby Walsh, Modelling the Golomb Ruler Problem. In IJCAI 99 Workshop on Non-binary Constraints, 1999.
See also problem 6 at http://www.csplib.org/.
The upper bound used is from the trivial construction where distances between consecutive marks are increasing powers of two.
Note that "Modeling and Programming with Gecode" uses this example as a case study.
