Query: parse(g,a) ---------------------------------------- (1) PrologToPiTRSProof (SOUND) We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes: parse_in_2: (b,f) app_in_3: (f,f,b) (b,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: parse_in_ga(Xs, T) -> U1_ga(Xs, T, app_in_aag(As, cons(a, cons(s(A, B, C), cons(b, Bs))), Xs)) app_in_aag(nil, X, X) -> app_out_aag(nil, X, X) app_in_aag(cons(X, Xs), Ys, cons(X, Zs)) -> U10_aag(X, Xs, Ys, Zs, app_in_aag(Xs, Ys, Zs)) U10_aag(X, Xs, Ys, Zs, app_out_aag(Xs, Ys, Zs)) -> app_out_aag(cons(X, Xs), Ys, cons(X, Zs)) U1_ga(Xs, T, app_out_aag(As, cons(a, cons(s(A, B, C), cons(b, Bs))), Xs)) -> U2_ga(Xs, T, app_in_gga(As, cons(s(a, s(A, B, C), b), Bs), Ys)) app_in_gga(nil, X, X) -> app_out_gga(nil, X, X) app_in_gga(cons(X, Xs), Ys, cons(X, Zs)) -> U10_gga(X, Xs, Ys, Zs, app_in_gga(Xs, Ys, Zs)) U10_gga(X, Xs, Ys, Zs, app_out_gga(Xs, Ys, Zs)) -> app_out_gga(cons(X, Xs), Ys, cons(X, Zs)) U2_ga(Xs, T, app_out_gga(As, cons(s(a, s(A, B, C), b), Bs), Ys)) -> U3_ga(Xs, T, parse_in_ga(Ys, T)) parse_in_ga(Xs, T) -> U4_ga(Xs, T, app_in_aag(As, cons(a, cons(s(A, B), cons(b, Bs))), Xs)) U4_ga(Xs, T, app_out_aag(As, cons(a, cons(s(A, B), cons(b, Bs))), Xs)) -> U5_ga(Xs, T, app_in_gga(As, cons(s(a, s(A, B), b), Bs), Ys)) U5_ga(Xs, T, app_out_gga(As, cons(s(a, s(A, B), b), Bs), Ys)) -> U6_ga(Xs, T, parse_in_ga(Ys, T)) parse_in_ga(Xs, T) -> U7_ga(Xs, T, app_in_aag(As, cons(a, cons(b, Bs)), Xs)) U7_ga(Xs, T, app_out_aag(As, cons(a, cons(b, Bs)), Xs)) -> U8_ga(Xs, T, app_in_gga(As, cons(s(a, b), Bs), Ys)) U8_ga(Xs, T, app_out_gga(As, cons(s(a, b), Bs), Ys)) -> U9_ga(Xs, T, parse_in_ga(Ys, T)) parse_in_ga(cons(s(A, B), nil), s(A, B)) -> parse_out_ga(cons(s(A, B), nil), s(A, B)) parse_in_ga(cons(s(A, B, C), nil), s(A, B, C)) -> parse_out_ga(cons(s(A, B, C), nil), s(A, B, C)) U9_ga(Xs, T, parse_out_ga(Ys, T)) -> parse_out_ga(Xs, T) U6_ga(Xs, T, parse_out_ga(Ys, T)) -> parse_out_ga(Xs, T) U3_ga(Xs, T, parse_out_ga(Ys, T)) -> parse_out_ga(Xs, T) The argument filtering Pi contains the following mapping: parse_in_ga(x1, x2) = parse_in_ga(x1) U1_ga(x1, x2, x3) = U1_ga(x3) app_in_aag(x1, x2, x3) = app_in_aag(x3)
