Query: rotate(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: rotate_in_2: (b,f) append2_in_3: (f,f,b) append1_in_3: (b,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: rotate_in_ga(X, Y) -> U1_ga(X, Y, append2_in_aag(A, B, X)) append2_in_aag(.(X, Xs), Ys, .(X, Zs)) -> U4_aag(X, Xs, Ys, Zs, append2_in_aag(Xs, Ys, Zs)) append2_in_aag([], Ys, Ys) -> append2_out_aag([], Ys, Ys) U4_aag(X, Xs, Ys, Zs, append2_out_aag(Xs, Ys, Zs)) -> append2_out_aag(.(X, Xs), Ys, .(X, Zs)) U1_ga(X, Y, append2_out_aag(A, B, X)) -> U2_ga(X, Y, append1_in_gga(B, A, Y)) append1_in_gga(.(X, Xs), Ys, .(X, Zs)) -> U3_gga(X, Xs, Ys, Zs, append1_in_gga(Xs, Ys, Zs)) append1_in_gga([], Ys, Ys) -> append1_out_gga([], Ys, Ys) U3_gga(X, Xs, Ys, Zs, append1_out_gga(Xs, Ys, Zs)) -> append1_out_gga(.(X, Xs), Ys, .(X, Zs)) U2_ga(X, Y, append1_out_gga(B, A, Y)) -> rotate_out_ga(X, Y) The argument filtering Pi contains the following mapping: rotate_in_ga(x1, x2) = rotate_in_ga(x1) U1_ga(x1, x2, x3) = U1_ga(x3) append2_in_aag(x1, x2, x3) = append2_in_aag(x3) .(x1, x2) = .(x1, x2) U4_aag(x1, x2, x3, x4, x5) = U4_aag(x1, x5) append2_out_aag(x1, x2, x3) = append2_out_aag(x1, x2) U2_ga(x1, x2, x3) = U2_ga(x3) append1_in_gga(x1, x2, x3) = append1_in_gga(x1, x2) U3_gga(x1, x2, x3, x4, x5) = U3_gga(x1, x5) [] = [] append1_out_gga(x1, x2, x3) = append1_out_gga(x3) rotate_out_ga(x1, x2) = rotate_out_ga(x2)
