Left Termination proof of /tmp/tmpF-9HIv/qicksort.pl

Left Termination of the query pattern qs_in_2(g, a) w.r.t. the given Prolog program could successfully be proven:

Clauses:

qs(.(X, Xs), Ys) :- ','(part(X, Xs, Littles, Bigs), ','(qs(Littles, Ls), ','(qs(Bigs, Bs), app(Ls, .(X, Bs), Ys)))).
qs([], []).
part(X, .(Y, Xs), .(Y, Ls), Bs) :- ','(gt(X, Y), part(X, Xs, Ls, Bs)).

part(X, [], [], []).
app(.(X, Xs), Ys, .(X, Zs)) :- app(Xs, Ys, Zs).
app([], Ys, Ys).
gt(s(X), s(Y)) :- gt(X, Y).
gt(s(0), 0).
le(s(X), s(Y)) :- le(X, Y).
le(0, s(0)).
le(0, 0).

Queries:

qs(g,a).

We use the technique of [30]. With regard to the inferred argument filtering the predicates were used in the following modes:
qs_in: (b,f)
part_in: (b,b,f,f)
gt_in: (b,b)
le_in: (b,b)
app_in: (b,b,f)

By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

U5_GGAA(X, Y, Xs, gt_out_gg) → PART_IN_GGAA(X, Xs)
The graph contains the following edges 1 >= 1, 3 >= 2
U7_GGAA(X, Y, Xs, le_out_gg) → PART_IN_GGAA(X, Xs)
The graph contains the following edges 1 >= 1, 3 >= 2
PART_IN_GGAA(X, .(Y, Xs)) → U7_GGAA(X, Y, Xs, le_in_gg(X, Y))
The graph contains the following edges 1 >= 1, 2 > 2, 2 > 3
