Platform claims not to support CPU time, falling back to wall time. Cannot find out cpu time on external processes, falling back to wall time! proof of /home/fs5/ayamada/tpdb/relative/Relative_05/rt1-2.trs # AProVE Commit ID: 2b684c7cda508b1711f707cb42f127e64fe1df88 ffrohn 20140415 dirty Termination of the given RelTRS could be proven: (0) RelTRS (1) RelTRSRRRProof [EQUIVALENT, 378 ms] (2) RelTRS (3) RIsEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Relative term rewrite system: The relative TRS consists of the following R rules: f(x) -> x g(x) -> x The relative TRS consists of the following S rules: f(x) -> g(x) g(x) -> f(x) ---------------------------------------- (1) RelTRSRRRProof (EQUIVALENT) We used the following monotonic ordering for rule removal: Polynomial interpretation [POLO]: POL(f(x_1)) = 1 + x_1 POL(g(x_1)) = 1 + x_1 With this ordering the following rules can be removed [MATRO] because they are oriented strictly: Rules from R: f(x) -> x g(x) -> x Rules from S: none ---------------------------------------- (2) Obligation: Relative term rewrite system: R is empty. The relative TRS consists of the following S rules: f(x) -> g(x) g(x) -> f(x) ---------------------------------------- (3) RIsEmptyProof (EQUIVALENT) The TRS R is empty. Hence, termination is trivially proven. ---------------------------------------- (4) YES
