Describes a list of finite domain variables with a finite
automaton. Equivalent to automaton(Vs, _, Vs, Nodes, Arcs,
[], [], _), a common use case of automaton/8. In the following
example, a list of binary finite domain variables is constrained to
contain at least two consecutive ones:
two_consecutive_ones(Vs) :-
automaton(Vs, [source(a),sink(c)],
[arc(a,0,a), arc(a,1,b),
arc(b,0,a), arc(b,1,c),
arc(c,0,c), arc(c,1,c)]).
Example query:
?- length(Vs, 3), two_consecutive_ones(Vs), label(Vs).
Vs = [0, 1, 1] ;
Vs = [1, 1, 0] ;
Vs = [1, 1, 1].
