chain
(
+Zs, +Relation
)
Zs
form a chain with respect to
Relation
.
Zs
is a list of finite domain variables that are a chain with respect to the partial order
Relation
, in the order they appear in the list.
Relation
must be #=, #=
<
, #
>
=,
#<
or #
>
. For example:
?- chain([X,Y,Z], #>=). X#>=Y, Y#>=Z.
