Query: sum(a,a,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: sum_in_3: (f,f,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: sum_in_aag(X, s(Y), s(Z)) -> U1_aag(X, Y, Z, sum_in_aag(X, Y, Z)) sum_in_aag(X, 0, X) -> sum_out_aag(X, 0, X) U1_aag(X, Y, Z, sum_out_aag(X, Y, Z)) -> sum_out_aag(X, s(Y), s(Z)) The argument filtering Pi contains the following mapping: sum_in_aag(x1, x2, x3) = sum_in_aag(x3) s(x1) = s(x1) U1_aag(x1, x2, x3, x4) = U1_aag(x4) sum_out_aag(x1, x2, x3) = sum_out_aag(x1, x2) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: sum_in_aag(X, s(Y), s(Z)) -> U1_aag(X, Y, Z, sum_in_aag(X, Y, Z)) sum_in_aag(X, 0, X) -> sum_out_aag(X, 0, X) U1_aag(X, Y, Z, sum_out_aag(X, Y, Z)) -> sum_out_aag(X, s(Y), s(Z)) The argument filtering Pi contains the following mapping: sum_in_aag(x1, x2, x3) = sum_in_aag(x3) s(x1) = s(x1) U1_aag(x1, x2, x3, x4) = U1_aag(x4) sum_out_aag(x1, x2, x3) = sum_out_aag(x1, x2) ----------------------------------------
