Q of the given QTRS could be proven: (0) QTRS (1) DependencyPairsProof [EQUIVALENT, 0 ms] (2) QDP (3) DependencyGraphProof [EQUIVALENT, 0 ms] (4) AND (5) QDP (6) UsableRulesProof [EQUIVALENT, 0 ms] (7) QDP (8) UsableRulesReductionPairsProof [EQUIVALENT, 0 ms] (9) QDP (10) PisEmptyProof [EQUIVALENT, 0 ms] (11) YES (12) QDP (13) QDPOrderProof [EQUIVALENT, 0 ms] (14) QDP (15) TransformationProof [EQUIVALENT, 0 ms] (16) QDP (17) QDPOrderProof [EQUIVALENT, 19.9 s] (18) QDP (19) PisEmptyProof [EQUIVALENT, 0 ms] (20) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: p(a(x0), p(b(a(x1)), x2)) -> p(x1, p(a(b(a(x1))), x2)) a(b(a(x0))) -> b(a(b(x0))) 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: P(a(x0), p(b(a(x1)), x2)) -> P(x1, p(a(b(a(x1))), x2)) P(a(x0), p(b(a(x1)), x2)) -> P(a(b(a(x1))), x2) P(a(x0), p(b(a(x1)), x2)) -> A(b(a(x1))) A(b(a(x0))) -> A(b(x0)) The TRS R consists of the following rules: p(a(x0), p(b(a(x1)), x2)) -> p(x1, p(a(b(a(x1))), x2)) a(b(a(x0))) -> b(a(b(x0))) 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 2 SCCs with 1 less node. ---------------------------------------- (4) Complex Obligation (AND) ---------------------------------------- (5) Obligation: Q DP problem: The TRS P consists of the following rules: A(b(a(x0))) -> A(b(x0)) The TRS R consists of the following rules: p(a(x0), p(b(a(x1)), x2)) -> p(x1, p(a(b(a(x1))), x2)) a(b(a(x0))) -> b(a(b(x0))) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (6) UsableRulesProof (EQUIVALENT) We can use the usable rules and reduction pair processor [LPAR04] with the Ce-compatible extension of the polynomial order that maps every function symbol to the sum of its arguments. Then, we can delete all non-usable rules [FROCOS05] from R.
