Query: sublist(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: sublist_in_2: (f,b) append_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: sublist_in_ag(X, Y) -> U2_ag(X, Y, append_in_aag(P, X1, Y)) append_in_aag([], Ys, Ys) -> append_out_aag([], Ys, Ys) append_in_aag(.(X, Xs), Ys, .(X, Zs)) -> U1_aag(X, Xs, Ys, Zs, append_in_aag(Xs, Ys, Zs)) U1_aag(X, Xs, Ys, Zs, append_out_aag(Xs, Ys, Zs)) -> append_out_aag(.(X, Xs), Ys, .(X, Zs)) U2_ag(X, Y, append_out_aag(P, X1, Y)) -> U3_ag(X, Y, append_in_aag(X2, X, P)) U3_ag(X, Y, append_out_aag(X2, X, P)) -> sublist_out_ag(X, Y) The argument filtering Pi contains the following mapping: sublist_in_ag(x1, x2) = sublist_in_ag(x2) U2_ag(x1, x2, x3) = U2_ag(x3) append_in_aag(x1, x2, x3) = append_in_aag(x3) append_out_aag(x1, x2, x3) = append_out_aag(x1, x2) .(x1, x2) = .(x1, x2) U1_aag(x1, x2, x3, x4, x5) = U1_aag(x1, x5) U3_ag(x1, x2, x3) = U3_ag(x3) sublist_out_ag(x1, x2) = sublist_out_ag(x1) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: sublist_in_ag(X, Y) -> U2_ag(X, Y, append_in_aag(P, X1, Y)) append_in_aag([], Ys, Ys) -> append_out_aag([], Ys, Ys) append_in_aag(.(X, Xs), Ys, .(X, Zs)) -> U1_aag(X, Xs, Ys, Zs, append_in_aag(Xs, Ys, Zs)) U1_aag(X, Xs, Ys, Zs, append_out_aag(Xs, Ys, Zs)) -> append_out_aag(.(X, Xs), Ys, .(X, Zs)) U2_ag(X, Y, append_out_aag(P, X1, Y)) -> U3_ag(X, Y, append_in_aag(X2, X, P)) U3_ag(X, Y, append_out_aag(X2, X, P)) -> sublist_out_ag(X, Y) The argument filtering Pi contains the following mapping: sublist_in_ag(x1, x2) = sublist_in_ag(x2) popout
