Left Termination proof of /tmp/tmpvWbdqC/quicksort-bf.pl

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

↳ Prolog

  ↳ PrologToPiTRSProof

Clauses:

qs([], []).
qs(.(X, Xs), Ys) :- ','(part(X, Xs, Littles, Bigs), ','(qs(Littles, Ls), ','(qs(Bigs, Bs), app(Ls, .(X, Bs), Ys)))).
part(X, .(Y, Xs), .(Y, Ls), Bs) :- ','(less(X, Y), part(X, Xs, Ls, Bs)).
part(X, .(Y, Xs), Ls, .(Y, Bs)) :- part(X, Xs, Ls, Bs).
part(X, [], [], []).
app([], X, X).
app(.(X, Xs), Ys, .(X, Zs)) :- app(Xs, Ys, Zs).
less(0, s(X)).
less(s(X), s(Y)) :- less(X, Y).

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)
less_in: (b,b)
app_in: (b,b,f)

We have to consider all (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

QS_IN_GA(.(X, Xs)) → U1_GA(X, part_in_ggaa(X, Xs))

The remaining pairs can at least be oriented weakly.

U2_GA(X, Bigs, qs_out_ga(Ls)) → QS_IN_GA(Bigs)
U1_GA(X, part_out_ggaa(Littles, Bigs)) → U2_GA(X, Bigs, qs_in_ga(Littles))
U1_GA(X, part_out_ggaa(Littles, Bigs)) → QS_IN_GA(Littles)

Used ordering: Polynomial interpretation [25]:

POL(.(x₁, x₂)) = 1 + x₁ + x₂
POL(0) = 1
POL(QS_IN_GA(x₁)) = x₁
POL(U1_GA(x₁, x₂)) = x₁ + x₂
POL(U1_ga(x₁, x₂)) = 0
POL(U2_GA(x₁, x₂, x₃)) = x₂
POL(U2_ga(x₁, x₂, x₃)) = 0
POL(U3_ga(x₁, x₂, x₃)) = 0
POL(U4_ga(x₁)) = 0
POL(U5_ggaa(x₁, x₂, x₃, x₄)) = 1 + x₂ + x₃
POL(U6_ggaa(x₁, x₂)) = 1 + x₁ + x₂
POL(U7_ggaa(x₁, x₂)) = 1 + x₁ + x₂
POL(U8_gga(x₁, x₂)) = 0
POL(U9_gg(x₁)) = 1 + x₁
POL([]) = 0
POL(app_in_gga(x₁, x₂)) = 0
POL(app_out_gga(x₁)) = 0
POL(less_in_gg(x₁, x₂)) = x₁
POL(less_out_gg) = 1
POL(part_in_ggaa(x₁, x₂)) = x₂
POL(part_out_ggaa(x₁, x₂)) = x₁ + x₂
POL(qs_in_ga(x₁)) = 0
POL(qs_out_ga(x₁)) = 0
POL(s(x₁)) = 1 + x₁

The following usable rules [17] were oriented:

U7_ggaa(Y, part_out_ggaa(Ls, Bs)) → part_out_ggaa(Ls, .(Y, Bs))
part_in_ggaa(X, []) → part_out_ggaa([], [])
part_in_ggaa(X, .(Y, Xs)) → U7_ggaa(Y, part_in_ggaa(X, Xs))
U5_ggaa(X, Y, Xs, less_out_gg) → U6_ggaa(Y, part_in_ggaa(X, Xs))
part_in_ggaa(X, .(Y, Xs)) → U5_ggaa(X, Y, Xs, less_in_gg(X, Y))
U6_ggaa(Y, part_out_ggaa(Ls, Bs)) → part_out_ggaa(.(Y, Ls), Bs)
