Denotes that we have one or several cliques of disequalities or that a
constraint is a variation of the constraint.
Variations may be related
to relaxation
(see, e.g., the ,
,
and constraints),
or to specialisation
(see, e.g., the constraint),
of the constraint.
Variations may also result from an extension of the notion of disequality
(see, e.g., the ,
,
and
constraints).
