Q of the given QTRS could be disproven: (0) QTRS (1) DependencyPairsProof [EQUIVALENT, 0 ms] (2) QDP (3) QDPOrderProof [EQUIVALENT, 68 ms] (4) QDP (5) DependencyGraphProof [EQUIVALENT, 0 ms] (6) QDP (7) NonTerminationLoopProof [COMPLETE, 0 ms] (8) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: +(x, +(y, z)) -> +(+(x, y), z) *(x, +(y, z)) -> +(*(x, y), *(x, z)) +(+(x, *(y, z)), *(y, u)) -> +(x, *(y, +(z, u))) Q is empty. ---------------------------------------- (1) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (2) Obligation: Q DP problem: The TRS P consists of the following rules: +^1(x, +(y, z)) -> +^1(+(x, y), z) +^1(x, +(y, z)) -> +^1(x, y) *^1(x, +(y, z)) -> +^1(*(x, y), *(x, z)) *^1(x, +(y, z)) -> *^1(x, y) *^1(x, +(y, z)) -> *^1(x, z) +^1(+(x, *(y, z)), *(y, u)) -> +^1(x, *(y, +(z, u))) +^1(+(x, *(y, z)), *(y, u)) -> *^1(y, +(z, u)) +^1(+(x, *(y, z)), *(y, u)) -> +^1(z, u) The TRS R consists of the following rules: +(x, +(y, z)) -> +(+(x, y), z) *(x, +(y, z)) -> +(*(x, y), *(x, z)) +(+(x, *(y, z)), *(y, u)) -> +(x, *(y, +(z, u))) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (3) QDPOrderProof (EQUIVALENT) We use the reduction pair processor [LPAR04,JAR06]. The following pairs can be oriented strictly and are deleted. +^1(x, +(y, z)) -> +^1(x, y) *^1(x, +(y, z)) -> *^1(x, y) *^1(x, +(y, z)) -> *^1(x, z) +^1(+(x, *(y, z)), *(y, u)) -> *^1(y, +(z, u)) +^1(+(x, *(y, z)), *(y, u)) -> +^1(z, u) The remaining pairs can at least be oriented weakly. Used ordering: Polynomial Order [NEGPOLO,POLO] with Interpretation: POL( *^1_2(x_1, x_2) ) = 2x_2 POL( +^1_2(x_1, x_2) ) = x_1 + x_2 POL( +_2(x_1, x_2) ) = x_1 + x_2 + 1 POL( *_2(x_1, x_2) ) = 2x_2 + 1 The following usable rules [FROCOS05] with respect to the argument filtering of the ordering [JAR06] were oriented: +(+(x, *(y, z)), *(y, u)) -> +(x, *(y, +(z, u))) +(x, +(y, z)) -> +(+(x, y), z) *(x, +(y, z)) -> +(*(x, y), *(x, z)) ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: +^1(x, +(y, z)) -> +^1(+(x, y), z) *^1(x, +(y, z)) -> +^1(*(x, y), *(x, z)) +^1(+(x, *(y, z)), *(y, u)) -> +^1(x, *(y, +(z, u))) The TRS R consists of the following rules: popout
