Q of the given QTRS could be proven: (0) QTRS (1) QTRS Reverse [EQUIVALENT, 0 ms] (2) QTRS (3) DependencyPairsProof [EQUIVALENT, 14 ms] (4) QDP (5) MRRProof [EQUIVALENT, 35 ms] (6) QDP (7) QDPOrderProof [EQUIVALENT, 541 ms] (8) QDP (9) PisEmptyProof [EQUIVALENT, 0 ms] (10) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(a(a(b(x1)))) -> b(b(x1)) b(b(x1)) -> a(b(a(a(x1)))) Q is empty. ---------------------------------------- (1) QTRS Reverse (EQUIVALENT) We applied the QTRS Reverse Processor [REVERSE]. ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: b(a(a(a(x1)))) -> b(b(x1)) b(b(x1)) -> a(a(b(a(x1)))) Q is empty. ---------------------------------------- (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: B(a(a(a(x1)))) -> B(b(x1)) B(a(a(a(x1)))) -> B(x1) B(b(x1)) -> B(a(x1)) The TRS R consists of the following rules: b(a(a(a(x1)))) -> b(b(x1)) b(b(x1)) -> a(a(b(a(x1)))) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (5) MRRProof (EQUIVALENT) By using the rule removal processor [LPAR04] with the following ordering, at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented. Strictly oriented dependency pairs: B(a(a(a(x1)))) -> B(x1) B(b(x1)) -> B(a(x1)) Used ordering: Polynomial interpretation [POLO]: POL(B(x_1)) = x_1 POL(a(x_1)) = 1 + x_1 POL(b(x_1)) = 3 + x_1 ---------------------------------------- (6) Obligation: Q DP problem: The TRS P consists of the following rules: B(a(a(a(x1)))) -> B(b(x1)) The TRS R consists of the following rules: b(a(a(a(x1)))) -> b(b(x1))
