The alldifferent Constraint: A Survey
<|reference_start|>The alldifferent Constraint: A Survey: The constraint of difference is known to the constraint programming community since Lauriere introduced Alice in 1978. Since then, several solving strategies have been designed for this constraint. In this paper we give both a practical overview and an abstract comparison of these different strategies.<|reference_end|>
