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)) Pi is empty. 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)) Pi is empty. ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LOPSTR] we result in the following initial DP problem: Pi DP problem: The TRS P consists of the following rules: BIN_TREE_IN_G(tree(X1, Left, Right)) -> U1_G(X1, Left, Right, bin_tree_in_g(Left)) BIN_TREE_IN_G(tree(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)) U1_G(X1, Left, Right, bin_tree_out_g(Left)) -> BIN_TREE_IN_G(Right) 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)) Pi is empty. popout
