Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 38 ms] (2) QTRS (3) Overlay + Local Confluence [EQUIVALENT, 0 ms] (4) QTRS (5) DependencyPairsProof [EQUIVALENT, 0 ms] (6) QDP (7) DependencyGraphProof [EQUIVALENT, 0 ms] (8) QDP (9) UsableRulesProof [EQUIVALENT, 1 ms] (10) QDP (11) QReductionProof [EQUIVALENT, 0 ms] (12) QDP (13) QDPSizeChangeProof [EQUIVALENT, 0 ms] (14) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: not(true) -> false not(false) -> true evenodd(x, 0) -> not(evenodd(x, s(0))) evenodd(0, s(0)) -> false evenodd(s(x), s(0)) -> evenodd(x, 0) Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Polynomial interpretation [POLO]: POL(0) = 0 POL(evenodd(x_1, x_2)) = 1 + 2*x_1 + 2*x_2 POL(false) = 0 POL(not(x_1)) = x_1 POL(s(x_1)) = 2*x_1 POL(true) = 0 With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly: evenodd(0, s(0)) -> false ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: not(true) -> false not(false) -> true evenodd(x, 0) -> not(evenodd(x, s(0))) evenodd(s(x), s(0)) -> evenodd(x, 0) Q is empty. ---------------------------------------- (3) Overlay + Local Confluence (EQUIVALENT) The TRS is overlay and locally confluent. By [NOC] we can switch to innermost. ---------------------------------------- (4) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: not(true) -> false not(false) -> true evenodd(x, 0) -> not(evenodd(x, s(0))) evenodd(s(x), s(0)) -> evenodd(x, 0) The set Q consists of the following terms: not(true) not(false) evenodd(x0, 0) evenodd(s(x0), s(0))
