....because of its importance is offered as a builtin constraint in most, if not all, major commercial and researchbased constraint systems. Several constraint propagation algorithms for the alldifferent constraint have been developed, ranging from weaker to stronger forms of local consistency (see [van Hoeve, 2001] for an excellent survey) Regin [1994] gives an O(n 2:5 ) algorithm for domain consistency of the alldifferent constraint, where n is the number of variables, that is based on relating alldifferent constraints to matchings. Leconte [1996] gives an O(n ) algorithm for range consistency, a ....
