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/rt3-3.trs # AProVE Commit ID: 2b684c7cda508b1711f707cb42f127e64fe1df88 ffrohn 20140415 dirty Termination of the given RelTRS could be disproven: (0) RelTRS (1) RelTRSLoopFinderProof [COMPLETE, 99 ms] (2) NO ---------------------------------------- (0) Obligation: Relative term rewrite system: The relative TRS consists of the following R rules: p(0, y) -> y p(s(x), y) -> s(p(x, y)) The relative TRS consists of the following S rules: p(x, y) -> s(p(x, y)) ---------------------------------------- (1) RelTRSLoopFinderProof (COMPLETE) The following loop was found: ---------- Loop: ---------- p(p(x', y'), y) -> p(s(p(x', y')), y) with rule p(x'', y'') -> s(p(x'', y'')) at position [0] and matcher [x'' / x', y'' / y'] p(s(p(x', y')), y) -> s(p(p(x', y'), y)) with rule p(s(x), y'') -> s(p(x, y'')) at position [] and matcher [x / p(x', y'), y'' / y] Now an instance of the first term with Matcher [ ] occurs in the last term at position [0]. Context: s([]) Therefore, the relative TRS problem does not terminate. ---------------------------------------- (2) NO
