Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 53 ms] (2) QTRS (3) RisEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: fac(0) -> 1 fac(s(x)) -> *(s(x), fac(x)) floop(0, y) -> y floop(s(x), y) -> floop(x, *(s(x), y)) *(x, 0) -> 0 *(x, s(y)) -> +(*(x, y), x) +(x, 0) -> x +(x, s(y)) -> s(+(x, y)) 1 -> s(0) fac(0) -> s(0) Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Quasi precedence: fac_1 > 1 > s_1 > 0 fac_1 > *_2 > +_2 > s_1 > 0 floop_2 > *_2 > +_2 > s_1 > 0 Status: fac_1: multiset status 0: multiset status 1: multiset status s_1: multiset status *_2: multiset status floop_2: [1,2] +_2: multiset status With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly: fac(0) -> 1 fac(s(x)) -> *(s(x), fac(x)) floop(0, y) -> y floop(s(x), y) -> floop(x, *(s(x), y)) *(x, 0) -> 0 *(x, s(y)) -> +(*(x, y), x) +(x, 0) -> x +(x, s(y)) -> s(+(x, y)) 1 -> s(0) fac(0) -> s(0) ---------------------------------------- (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 popout
