(14) UsableRulesReductionPairsProof (EQUIVALENT transformation)

By using the usable rules with reduction pair processor [LPAR04] with a polynomial ordering [POLO], all dependency pairs and the corresponding usable rules [FROCOS05] can be oriented non-strictly. All non-usable rules are removed, and those dependency pairs and usable rules that have been oriented strictly or contain non-usable symbols in their left-hand side are removed as well.

The following dependency pairs can be deleted:

FLATTEN29_IN_GGGA(atom(T90), atom(T103), T104) → FLATTEN40_IN_GA(T104)
FLATTEN40_IN_GA(cons(atom(T120), T121)) → FLATTEN40_IN_GA(T121)
FLATTEN40_IN_GA(cons(cons(T130, T131), T132)) → FLATTEN29_IN_GGGA(T130, T131, T132)
FLATTEN29_IN_GGGA(atom(T90), cons(T142, T143), T144) → FLATTEN29_IN_GGGA(T142, T143, T144)

No rules are removed from R.

Used ordering: POLO with Polynomial interpretation [POLO]:

POL(FLATTEN29_IN_GGGA(x₁, x₂, x₃)) = 2·x₁ + 2·x₂ + 2·x₃   
POL(FLATTEN40_IN_GA(x₁)) = 1 + 2·x₁

(23) UsableRulesReductionPairsProof (EQUIVALENT transformation)

By using the usable rules with reduction pair processor [LPAR04] with a polynomial ordering [POLO], all dependency pairs and the corresponding usable rules [FROCOS05] can be oriented non-strictly. All non-usable rules are removed, and those dependency pairs and usable rules that have been oriented strictly or contain non-usable symbols in their left-hand side are removed as well.

The following dependency pairs can be deleted:

COUNT1_IN_GA(cons(atom(T8), cons(cons(T51, T52), T53))) → U9_GA(flatten24_in_ggga(T51, T52, T53))

U12_GA(flatten29_out_ggga(T190)) → COUNT1_IN_GA(T190)
