Query: less(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: less_in_2: (f,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: less_in_ag(0, s(X1)) -> less_out_ag(0, s(X1)) less_in_ag(s(X), s(Y)) -> U1_ag(X, Y, less_in_ag(X, Y)) U1_ag(X, Y, less_out_ag(X, Y)) -> less_out_ag(s(X), s(Y)) The argument filtering Pi contains the following mapping: less_in_ag(x1, x2) = less_in_ag(x2) s(x1) = s(x1) less_out_ag(x1, x2) = less_out_ag(x1) U1_ag(x1, x2, x3) = U1_ag(x3) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: less_in_ag(0, s(X1)) -> less_out_ag(0, s(X1)) less_in_ag(s(X), s(Y)) -> U1_ag(X, Y, less_in_ag(X, Y)) U1_ag(X, Y, less_out_ag(X, Y)) -> less_out_ag(s(X), s(Y)) The argument filtering Pi contains the following mapping: less_in_ag(x1, x2) = less_in_ag(x2) s(x1) = s(x1) less_out_ag(x1, x2) = less_out_ag(x1) U1_ag(x1, x2, x3) = U1_ag(x3) ---------------------------------------- popout
