Q of the given QTRS could be disproven: (0) QTRS (1) AAECC Innermost [EQUIVALENT, 0 ms] (2) QTRS (3) DependencyPairsProof [EQUIVALENT, 0 ms] (4) QDP (5) DependencyGraphProof [EQUIVALENT, 0 ms] (6) AND (7) QDP (8) UsableRulesProof [EQUIVALENT, 0 ms] (9) QDP (10) QReductionProof [EQUIVALENT, 0 ms] (11) QDP (12) QDPSizeChangeProof [EQUIVALENT, 0 ms] (13) YES (14) QDP (15) MNOCProof [EQUIVALENT, 0 ms] (16) QDP (17) NonLoopProof [COMPLETE, 52 ms] (18) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(tt, x) -> f(isDouble(x), s(s(x))) isDouble(s(s(x))) -> isDouble(x) isDouble(0) -> tt Q is empty. ---------------------------------------- (1) AAECC Innermost (EQUIVALENT) We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is isDouble(s(s(x))) -> isDouble(x) isDouble(0) -> tt The TRS R 2 is f(tt, x) -> f(isDouble(x), s(s(x))) The signature Sigma is {f_2} ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(tt, x) -> f(isDouble(x), s(s(x))) isDouble(s(s(x))) -> isDouble(x) isDouble(0) -> tt The set Q consists of the following terms: f(tt, x0) isDouble(s(s(x0))) isDouble(0) ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: F(tt, x) -> F(isDouble(x), s(s(x))) F(tt, x) -> ISDOUBLE(x) ISDOUBLE(s(s(x))) -> ISDOUBLE(x) The TRS R consists of the following rules: f(tt, x) -> f(isDouble(x), s(s(x))) isDouble(s(s(x))) -> isDouble(x) isDouble(0) -> tt The set Q consists of the following terms: f(tt, x0)
