Query: bin_tree(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: bin_tree_in_1: (b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: bin_tree_in_g(void) -> bin_tree_out_g(void) bin_tree_in_g(tree(X1, Left, Right)) -> U1_g(X1, Left, Right, bin_tree_in_g(Left)) U1_g(X1, Left, Right, bin_tree_out_g(Left)) -> U2_g(X1, Left, Right, bin_tree_in_g(Right)) U2_g(X1, Left, Right, bin_tree_out_g(Right)) -> bin_tree_out_g(tree(X1, Left, Right)) The argument filtering Pi contains the following mapping: bin_tree_in_g(x1) = bin_tree_in_g(x1) void = void bin_tree_out_g(x1) = bin_tree_out_g tree(x1, x2, x3) = tree(x1, x2, x3) U1_g(x1, x2, x3, x4) = U1_g(x3, x4) U2_g(x1, x2, x3, x4) = U2_g(x4) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- (2) Obligation: Pi-finite rewrite system: The TRS R consists of the following rules: bin_tree_in_g(void) -> bin_tree_out_g(void) bin_tree_in_g(tree(X1, Left, Right)) -> U1_g(X1, Left, Right, bin_tree_in_g(Left)) U1_g(X1, Left, Right, bin_tree_out_g(Left)) -> U2_g(X1, Left, Right, bin_tree_in_g(Right)) U2_g(X1, Left, Right, bin_tree_out_g(Right)) -> bin_tree_out_g(tree(X1, Left, Right)) The argument filtering Pi contains the following mapping: bin_tree_in_g(x1) = bin_tree_in_g(x1) void = void bin_tree_out_g(x1) = bin_tree_out_g tree(x1, x2, x3) = tree(x1, x2, x3) U1_g(x1, x2, x3, x4) = U1_g(x3, x4) U2_g(x1, x2, x3, x4) = U2_g(x4)
