Query: goal(g) ---------------------------------------- (1) PrologToPiTRSProof (SOUND) We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes: goal_in_1: (b) s2t_in_2: (b,f) tappend_in_3: (b,f,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: goal_in_g(X) -> U6_g(X, s2t_in_ga(X, T1)) s2t_in_ga(s(X), node(T, Y, T)) -> U3_ga(X, T, Y, s2t_in_ga(X, T)) s2t_in_ga(s(X), node(nil, Y, T)) -> U4_ga(X, Y, T, s2t_in_ga(X, T)) s2t_in_ga(s(X), node(T, Y, nil)) -> U5_ga(X, T, Y, s2t_in_ga(X, T)) s2t_in_ga(s(X), node(nil, Y, nil)) -> s2t_out_ga(s(X), node(nil, Y, nil)) s2t_in_ga(0, nil) -> s2t_out_ga(0, nil) U5_ga(X, T, Y, s2t_out_ga(X, T)) -> s2t_out_ga(s(X), node(T, Y, nil)) U4_ga(X, Y, T, s2t_out_ga(X, T)) -> s2t_out_ga(s(X), node(nil, Y, T)) U3_ga(X, T, Y, s2t_out_ga(X, T)) -> s2t_out_ga(s(X), node(T, Y, T)) U6_g(X, s2t_out_ga(X, T1)) -> U7_g(X, tappend_in_gaa(T1, T2, T3)) tappend_in_gaa(nil, T, T) -> tappend_out_gaa(nil, T, T) tappend_in_gaa(node(nil, X, T2), T1, node(T1, X, T2)) -> tappend_out_gaa(node(nil, X, T2), T1, node(T1, X, T2)) tappend_in_gaa(node(T1, X, nil), T2, node(T1, X, T2)) -> tappend_out_gaa(node(T1, X, nil), T2, node(T1, X, T2)) tappend_in_gaa(node(T1, X, T2), T3, node(U, X, T2)) -> U1_gaa(T1, X, T2, T3, U, tappend_in_gaa(T1, T3, U)) tappend_in_gaa(node(T1, X, T2), T3, node(T1, X, U)) -> U2_gaa(T1, X, T2, T3, U, tappend_in_gaa(T2, T3, U)) U2_gaa(T1, X, T2, T3, U, tappend_out_gaa(T2, T3, U)) -> tappend_out_gaa(node(T1, X, T2), T3, node(T1, X, U)) U1_gaa(T1, X, T2, T3, U, tappend_out_gaa(T1, T3, U)) -> tappend_out_gaa(node(T1, X, T2), T3, node(U, X, T2)) U7_g(X, tappend_out_gaa(T1, T2, T3)) -> goal_out_g(X) The argument filtering Pi contains the following mapping: goal_in_g(x1) = goal_in_g(x1) U6_g(x1, x2) = U6_g(x1, x2) s2t_in_ga(x1, x2) = s2t_in_ga(x1) s(x1) = s(x1) U3_ga(x1, x2, x3, x4) = U3_ga(x1, x4) popout
