Query: normal(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: normal_in_2: (b,f) rewrite_in_2: (b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: normal_in_ga(F, N) -> U1_ga(F, N, rewrite_in_ga(F, F1)) rewrite_in_ga(op(op(A, B), C), op(A, op(B, C))) -> rewrite_out_ga(op(op(A, B), C), op(A, op(B, C))) rewrite_in_ga(op(A, op(B, C)), op(A, L)) -> U3_ga(A, B, C, L, rewrite_in_ga(op(B, C), L)) U3_ga(A, B, C, L, rewrite_out_ga(op(B, C), L)) -> rewrite_out_ga(op(A, op(B, C)), op(A, L)) U1_ga(F, N, rewrite_out_ga(F, F1)) -> U2_ga(F, N, normal_in_ga(F1, N)) normal_in_ga(F, F) -> normal_out_ga(F, F) U2_ga(F, N, normal_out_ga(F1, N)) -> normal_out_ga(F, N) The argument filtering Pi contains the following mapping: normal_in_ga(x1, x2) = normal_in_ga(x1) U1_ga(x1, x2, x3) = U1_ga(x3) rewrite_in_ga(x1, x2) = rewrite_in_ga(x1) op(x1, x2) = op(x1, x2) rewrite_out_ga(x1, x2) = rewrite_out_ga(x2) U3_ga(x1, x2, x3, x4, x5) = U3_ga(x1, x5) U2_ga(x1, x2, x3) = U2_ga(x3) normal_out_ga(x1, x2) = normal_out_ga(x2) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog
