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

Q DP problem:
The TRS P consists of the following rules:

U4_GA(app_out_aag(As, cons(a, cons(s(A, B), cons(b, Bs))))) → U5_GA(app_in_gga(As, cons(s(a, s(A, B), b), Bs)))
PARSE_IN_GA(Xs) → U7_GA(app_in_aag(Xs))
U5_GA(app_out_gga(Ys)) → PARSE_IN_GA(Ys)
U7_GA(app_out_aag(As, cons(a, cons(b, Bs)))) → U8_GA(app_in_gga(As, cons(s(a, b), Bs)))
PARSE_IN_GA(Xs) → U1_GA(app_in_aag(Xs))
PARSE_IN_GA(Xs) → U4_GA(app_in_aag(Xs))
U2_GA(app_out_gga(Ys)) → PARSE_IN_GA(Ys)
U8_GA(app_out_gga(Ys)) → PARSE_IN_GA(Ys)
U1_GA(app_out_aag(As, cons(a, cons(s(A, B, C), cons(b, Bs))))) → U2_GA(app_in_gga(As, cons(s(a, s(A, B, C), b), Bs)))

The TRS R consists of the following rules:

app_in_aag(X) → app_out_aag(nil, X)
app_in_aag(cons(X, Zs)) → U10_aag(X, app_in_aag(Zs))
app_in_gga(nil, X) → app_out_gga(X)
app_in_gga(cons(X, Xs), Ys) → U10_gga(X, app_in_gga(Xs, Ys))
U10_aag(X, app_out_aag(Xs, Ys)) → app_out_aag(cons(X, Xs), Ys)
U10_gga(X, app_out_gga(Zs)) → app_out_gga(cons(X, Zs))

The set Q consists of the following terms:

app_in_aag(x0)
app_in_gga(x0, x1)
U10_aag(x0, x1)
U10_gga(x0, x1)

We have to consider all (P,Q,R)-chains.
By using the rule removal processor [15] with the following polynomial ordering [25], at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:

U4_GA(app_out_aag(As, cons(a, cons(s(A, B), cons(b, Bs))))) → U5_GA(app_in_gga(As, cons(s(a, s(A, B), b), Bs)))
U5_GA(app_out_gga(Ys)) → PARSE_IN_GA(Ys)
U7_GA(app_out_aag(As, cons(a, cons(b, Bs)))) → U8_GA(app_in_gga(As, cons(s(a, b), Bs)))
U2_GA(app_out_gga(Ys)) → PARSE_IN_GA(Ys)
U1_GA(app_out_aag(As, cons(a, cons(s(A, B, C), cons(b, Bs))))) → U2_GA(app_in_gga(As, cons(s(a, s(A, B, C), b), Bs)))

Used ordering: POLO with Polynomial interpretation [25]:

POL(PARSE_IN_GA(x₁)) = x₁
POL(U10_aag(x₁, x₂)) = 2 + 2·x₁ + x₂
POL(U10_gga(x₁, x₂)) = 2 + 2·x₁ + x₂
POL(U1_GA(x₁)) = x₁
POL(U2_GA(x₁)) = 1 + x₁
POL(U4_GA(x₁)) = x₁
POL(U5_GA(x₁)) = 2 + x₁
POL(U7_GA(x₁)) = x₁
POL(U8_GA(x₁)) = x₁
POL(a) = 2
POL(app_in_aag(x₁)) = x₁
POL(app_in_gga(x₁, x₂)) = x₁ + x₂
POL(app_out_aag(x₁, x₂)) = x₁ + x₂
POL(app_out_gga(x₁)) = x₁
POL(b) = 0
POL(cons(x₁, x₂)) = 2 + 2·x₁ + x₂
POL(nil) = 0
POL(s(x₁, x₂)) = x₁ + x₂
POL(s(x₁, x₂, x₃)) = x₁ + x₂ + 2·x₃
