Abstract [en]

The paper presents propagation rules that are common to the minimum constraint family and to the number of distinct values constraint family. One original contribution is to provide a geometrical interpretation of these rules that can be used by a generic sweep pruning algorithm. Finally one practical interest of the paper is to describe an implementation of the number of distinct values constraint. This is a quite common counting constraint that one encounters in many practical applications such as timetabling or frequency allocation problems.
