Q of the given QTRS could be proven: (0) QTRS (1) DependencyPairsProof [EQUIVALENT, 0 ms] (2) QDP (3) DependencyGraphProof [EQUIVALENT, 0 ms] (4) QDP (5) TransformationProof [EQUIVALENT, 0 ms] (6) QDP (7) DependencyGraphProof [EQUIVALENT, 0 ms] (8) QDP (9) SemLabProof [SOUND, 47 ms] (10) QDP (11) DependencyGraphProof [EQUIVALENT, 0 ms] (12) QDP (13) UsableRulesReductionPairsProof [EQUIVALENT, 6 ms] (14) QDP (15) DependencyGraphProof [EQUIVALENT, 0 ms] (16) TRUE ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(f, a(f, x)) -> a(x, g) a(x, g) -> a(f, a(g, a(f, x))) Q is empty. ---------------------------------------- (1) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (2) Obligation: Q DP problem: The TRS P consists of the following rules: A(f, a(f, x)) -> A(x, g) A(x, g) -> A(f, a(g, a(f, x))) A(x, g) -> A(g, a(f, x)) A(x, g) -> A(f, x) The TRS R consists of the following rules: a(f, a(f, x)) -> a(x, g) a(x, g) -> a(f, a(g, a(f, x))) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (3) DependencyGraphProof (EQUIVALENT) The approximation of the Dependency Graph [LPAR04,FROCOS05,EDGSTAR] contains 1 SCC with 1 less node. ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: A(x, g) -> A(f, a(g, a(f, x))) A(f, a(f, x)) -> A(x, g) A(x, g) -> A(f, x) The TRS R consists of the following rules: a(f, a(f, x)) -> a(x, g) a(x, g) -> a(f, a(g, a(f, x))) Q is empty.
