Query: append3(g,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: append3_in_4: (b,b,b,f) append_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: append3_in_ggga(A, B, C, D) -> U2_ggga(A, B, C, D, append_in_gga(A, B, E)) append_in_gga([], L, L) -> append_out_gga([], L, L) append_in_gga(.(H, L1), L2, .(H, L3)) -> U1_gga(H, L1, L2, L3, append_in_gga(L1, L2, L3)) U1_gga(H, L1, L2, L3, append_out_gga(L1, L2, L3)) -> append_out_gga(.(H, L1), L2, .(H, L3)) U2_ggga(A, B, C, D, append_out_gga(A, B, E)) -> U3_ggga(A, B, C, D, append_in_gga(E, C, D)) U3_ggga(A, B, C, D, append_out_gga(E, C, D)) -> append3_out_ggga(A, B, C, D) The argument filtering Pi contains the following mapping: append3_in_ggga(x1, x2, x3, x4) = append3_in_ggga(x1, x2, x3) U2_ggga(x1, x2, x3, x4, x5) = U2_ggga(x3, x5) append_in_gga(x1, x2, x3) = append_in_gga(x1, x2) [] = [] append_out_gga(x1, x2, x3) = append_out_gga(x3) .(x1, x2) = .(x1, x2) U1_gga(x1, x2, x3, x4, x5) = U1_gga(x1, x5) U3_ggga(x1, x2, x3, x4, x5) = U3_ggga(x5) append3_out_ggga(x1, x2, x3, x4) = append3_out_ggga(x4) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: append3_in_ggga(A, B, C, D) -> U2_ggga(A, B, C, D, append_in_gga(A, B, E)) popout
