Redundant disequalities in the Latin Square problem
This paper studies the redundancy properties of the constraints used
when formulating the well known Latin Square problem. This problem is
often formulated using either binary disequalities or
\alldiff~global constraints. Both formulations contain redundant
constraints. A complete classification of all redundant sets of
constraints, be they binary or global, is performed for any .
