Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 34 ms] (2) QTRS (3) RisEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: +(*(x, y), *(x, z)) -> *(x, +(y, z)) +(+(x, y), z) -> +(x, +(y, z)) +(*(x, y), +(*(x, z), u)) -> +(*(x, +(y, z)), u) Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Knuth-Bendix order [KBO] with precedence:u > *_2 > +_2 and weight map: u=1 *_2=0 +_2=0 The variable weight is 1With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly: +(*(x, y), *(x, z)) -> *(x, +(y, z)) +(+(x, y), z) -> +(x, +(y, z)) +(*(x, y), +(*(x, z), u)) -> +(*(x, +(y, z)), u) ---------------------------------------- (2) Obligation: Q restricted rewrite system: R is empty. Q is empty. ---------------------------------------- (3) RisEmptyProof (EQUIVALENT) The TRS R is empty. Hence, termination is trivially proven. ---------------------------------------- (4) YES
