A number of global constraints are available which directly correspond
(and are in fact implemented via) their counterparts in
lib(ic_global):
-
alldifferent(+List)
-
All list elements are different
- occurrences(++Value,+List,?N)
-
Value occurs N times in List
- atmost(++N,+List,++Value)
-
Value occurs at most N times in List
