YES proof of /export/starexec/sandbox2/benchmark/theBenchmark.xml # AProVE Commit ID: 794c25de1cacf0d048858bcd21c9a779e1221865 marcel 20200619 unpublished dirty Termination w.r.t. Q of the given QTRS could be proven: (0) QTRS (1) DependencyPairsProof [EQUIVALENT, 0 ms] (2) QDP (3) QDPOrderProof [EQUIVALENT, 34 ms] (4) QDP (5) QDPBoundsTAProof [EQUIVALENT, 140 ms] (6) QDP (7) PisEmptyProof [EQUIVALENT, 0 ms] (8) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(y, f(y, x)) -> f(f(a, y), f(a, y)) 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: F(y, f(y, x)) -> F(f(a, y), f(a, y)) F(y, f(y, x)) -> F(a, y) The TRS R consists of the following rules: f(y, f(y, x)) -> f(f(a, y), f(a, y)) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (3) QDPOrderProof (EQUIVALENT) We use the reduction pair processor [LPAR04,JAR06]. The following pairs can be oriented strictly and are deleted. F(y, f(y, x)) -> F(a, y) The remaining pairs can at least be oriented weakly. Used ordering: Matrix interpretation [MATRO] with arctic natural numbers [ARCTIC]: <<< POL(F(x_1, x_2)) = [[0A]] + [[0A]] * x_1 + [[4A]] * x_2 >>> <<< POL(f(x_1, x_2)) = [[1A]] + [[1A]] * x_1 + [[1A]] * x_2 >>> <<< POL(a) = [[0A]] >>> The following usable rules [FROCOS05] with respect to the argument filtering of the ordering [JAR06] were oriented: f(y, f(y, x)) -> f(f(a, y), f(a, y)) ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: F(y, f(y, x)) -> F(f(a, y), f(a, y)) The TRS R consists of the following rules: f(y, f(y, x)) -> f(f(a, y), f(a, y)) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (5) QDPBoundsTAProof (EQUIVALENT) The DP-Problem (P, R) could be shown to be Match-(raise-)DP-Bounded [TAB_NONLEFTLINEAR] by 2 for the Rule: F(y, f(y, x)) -> F(f(a, y), f(a, y)) by considering the usable rules:
