Query: ordered(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: ordered_in_1: (b) le_in_2: (b,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: ordered_in_g([]) -> ordered_out_g([]) ordered_in_g(.(X, [])) -> ordered_out_g(.(X, [])) ordered_in_g(.(X, .(Y, Xs))) -> U1_g(X, Y, Xs, le_in_gg(X, Y)) le_in_gg(s(X), s(Y)) -> U3_gg(X, Y, le_in_gg(X, Y)) le_in_gg(0, s(0)) -> le_out_gg(0, s(0)) le_in_gg(0, 0) -> le_out_gg(0, 0) U3_gg(X, Y, le_out_gg(X, Y)) -> le_out_gg(s(X), s(Y)) U1_g(X, Y, Xs, le_out_gg(X, Y)) -> U2_g(X, Y, Xs, ordered_in_g(.(Y, Xs))) U2_g(X, Y, Xs, ordered_out_g(.(Y, Xs))) -> ordered_out_g(.(X, .(Y, Xs))) The argument filtering Pi contains the following mapping: ordered_in_g(x1) = ordered_in_g(x1) [] = [] ordered_out_g(x1) = ordered_out_g .(x1, x2) = .(x1, x2) U1_g(x1, x2, x3, x4) = U1_g(x2, x3, x4) le_in_gg(x1, x2) = le_in_gg(x1, x2) s(x1) = s(x1) U3_gg(x1, x2, x3) = U3_gg(x3) 0 = 0
