Query: reverse(g,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: reverse_in_3: (b,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: reverse_in_gga([], X, X) -> reverse_out_gga([], X, X) reverse_in_gga(.(X, Y), Z, U) -> U1_gga(X, Y, Z, U, reverse_in_gga(Y, Z, .(X, U))) U1_gga(X, Y, Z, U, reverse_out_gga(Y, Z, .(X, U))) -> reverse_out_gga(.(X, Y), Z, U) The argument filtering Pi contains the following mapping: reverse_in_gga(x1, x2, x3) = reverse_in_gga(x1, x2) [] = [] reverse_out_gga(x1, x2, x3) = reverse_out_gga(x3) .(x1, x2) = .(x1, x2) U1_gga(x1, x2, x3, x4, x5) = U1_gga(x5) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: reverse_in_gga([], X, X) -> reverse_out_gga([], X, X) reverse_in_gga(.(X, Y), Z, U) -> U1_gga(X, Y, Z, U, reverse_in_gga(Y, Z, .(X, U))) U1_gga(X, Y, Z, U, reverse_out_gga(Y, Z, .(X, U))) -> reverse_out_gga(.(X, Y), Z, U) The argument filtering Pi contains the following mapping: reverse_in_gga(x1, x2, x3) = reverse_in_gga(x1, x2) [] = [] reverse_out_gga(x1, x2, x3) = reverse_out_gga(x3) .(x1, x2) = .(x1, x2) U1_gga(x1, x2, x3, x4, x5) = U1_gga(x5) ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LOPSTR] we result in the following initial DP problem: popout
