Query: select(a,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: select_in_3: (f,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: select_in_aga(X, .(X, Xs), Xs) -> select_out_aga(X, .(X, Xs), Xs) select_in_aga(X, .(Y, Xs), .(Y, Zs)) -> U1_aga(X, Y, Xs, Zs, select_in_aga(X, Xs, Zs)) U1_aga(X, Y, Xs, Zs, select_out_aga(X, Xs, Zs)) -> select_out_aga(X, .(Y, Xs), .(Y, Zs)) The argument filtering Pi contains the following mapping: select_in_aga(x1, x2, x3) = select_in_aga(x2) .(x1, x2) = .(x1, x2) select_out_aga(x1, x2, x3) = select_out_aga(x1, x3) U1_aga(x1, x2, x3, x4, x5) = U1_aga(x2, 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: select_in_aga(X, .(X, Xs), Xs) -> select_out_aga(X, .(X, Xs), Xs) select_in_aga(X, .(Y, Xs), .(Y, Zs)) -> U1_aga(X, Y, Xs, Zs, select_in_aga(X, Xs, Zs)) U1_aga(X, Y, Xs, Zs, select_out_aga(X, Xs, Zs)) -> select_out_aga(X, .(Y, Xs), .(Y, Zs)) The argument filtering Pi contains the following mapping: select_in_aga(x1, x2, x3) = select_in_aga(x2) .(x1, x2) = .(x1, x2) select_out_aga(x1, x2, x3) = select_out_aga(x1, x3) U1_aga(x1, x2, x3, x4, x5) = U1_aga(x2, x5) ----------------------------------------
