Query: q(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: q_in_1: (b) p_in_2: (b,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: q_in_g(X) -> U1_g(X, p_in_gg(X, 0)) p_in_gg(0, X1) -> p_out_gg(0, X1) p_in_gg(s(X), Y) -> U2_gg(X, Y, p_in_gg(X, s(Y))) U2_gg(X, Y, p_out_gg(X, s(Y))) -> p_out_gg(s(X), Y) U1_g(X, p_out_gg(X, 0)) -> q_out_g(X) Pi is empty. Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: q_in_g(X) -> U1_g(X, p_in_gg(X, 0)) p_in_gg(0, X1) -> p_out_gg(0, X1) p_in_gg(s(X), Y) -> U2_gg(X, Y, p_in_gg(X, s(Y))) U2_gg(X, Y, p_out_gg(X, s(Y))) -> p_out_gg(s(X), Y) U1_g(X, p_out_gg(X, 0)) -> q_out_g(X) Pi is empty. ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LOPSTR] we result in the following initial DP problem: Pi DP problem: The TRS P consists of the following rules: Q_IN_G(X) -> U1_G(X, p_in_gg(X, 0)) Q_IN_G(X) -> P_IN_GG(X, 0) P_IN_GG(s(X), Y) -> U2_GG(X, Y, p_in_gg(X, s(Y))) P_IN_GG(s(X), Y) -> P_IN_GG(X, s(Y)) The TRS R consists of the following rules: popout
