Q of the given QTRS could be proven: (0) QTRS (1) AAECC Innermost [EQUIVALENT, 0 ms] (2) QTRS (3) DependencyPairsProof [EQUIVALENT, 0 ms] (4) QDP (5) UsableRulesProof [EQUIVALENT, 0 ms] (6) QDP (7) QReductionProof [EQUIVALENT, 0 ms] (8) QDP (9) TransformationProof [EQUIVALENT, 0 ms] (10) QDP (11) DependencyGraphProof [EQUIVALENT, 0 ms] (12) TRUE ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(x, y, z) -> g(x, y, z) g(0, 1, x) -> f(x, x, x) a -> b a -> c Q is empty. ---------------------------------------- (1) AAECC Innermost (EQUIVALENT) We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is none The TRS R 2 is f(x, y, z) -> g(x, y, z) g(0, 1, x) -> f(x, x, x) a -> b a -> c The signature Sigma is {f_3, g_3, a, b, c} ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(x, y, z) -> g(x, y, z) g(0, 1, x) -> f(x, x, x) a -> b a -> c The set Q consists of the following terms: f(x0, x1, x2) g(0, 1, x0) a ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: F(x, y, z) -> G(x, y, z) G(0, 1, x) -> F(x, x, x) The TRS R consists of the following rules: f(x, y, z) -> g(x, y, z) g(0, 1, x) -> f(x, x, x) a -> b a -> c The set Q consists of the following terms: f(x0, x1, x2) g(0, 1, x0) a We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (5) UsableRulesProof (EQUIVALENT) As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [LPAR04] we can delete all non-usable rules [FROCOS05] from R. ---------------------------------------- (6) Obligation: Q DP problem: The TRS P consists of the following rules: F(x, y, z) -> G(x, y, z) G(0, 1, x) -> F(x, x, x) R is empty. The set Q consists of the following terms: f(x0, x1, x2) g(0, 1, x0) a We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (7) QReductionProof (EQUIVALENT) We deleted the following terms from Q as each root-symbol of these terms does neither occur in P nor in R.[THIEMANN]. f(x0, x1, x2) g(0, 1, x0) a ---------------------------------------- (8) Obligation: Q DP problem: The TRS P consists of the following rules: F(x, y, z) -> G(x, y, z) G(0, 1, x) -> F(x, x, x) R is empty. Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (9) TransformationProof (EQUIVALENT) By instantiating [LPAR04] the rule F(x, y, z) -> G(x, y, z) we obtained the following new rules [LPAR04]: (F(z0, z0, z0) -> G(z0, z0, z0),F(z0, z0, z0) -> G(z0, z0, z0)) ---------------------------------------- (10) Obligation: Q DP problem: The TRS P consists of the following rules: G(0, 1, x) -> F(x, x, x) F(z0, z0, z0) -> G(z0, z0, z0) R is empty. Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (11) DependencyGraphProof (EQUIVALENT) The approximation of the Dependency Graph [LPAR04,FROCOS05,EDGSTAR] contains 0 SCCs with 2 less nodes. ---------------------------------------- (12) TRUE
