Rewrite Strategy: INNERMOST
----------------------------------------

(25) CpxTypedWeightedTrsToRntsProof (UPPER BOUND(ID))
Transformed the TRS into an over-approximating RNTS by (improved) Size Abstraction.
The constant constructors are abstracted as follows:

   0 => 0
   nil => 2
   nil1 => 3
   01 => 1

The transformation into a RNTS is sound, since:

(a) The obligation is a constructor system where every type has a constant constructor,

(b) The following defined symbols do not have to be completely defined, as they can never occur inside other defined symbols:

   A__SEL_2
   A__FIRST_2
   A__FROM_1
   A__SEL1_2
   A__FIRST1_2
   A__QUOTE_1
   A__QUOTE1_1
   A__UNQUOTE_1
   A__UNQUOTE1_1
   A__FCONS_2
   MARK_1

(c) The following functions are completely defined:

   a__sel_2
   a__first_2
   a__from_1
   a__sel1_2
   a__first1_2
   a__quote_1
   a__quote1_1
   a__unquote_1
   a__unquote1_1
   a__fcons_2
   mark_1

Due to the following rules being added:

   a__sel(v0, v1) -> null_a__sel [0]
   a__first(v0, v1) -> null_a__first [0]
   a__from(v0) -> null_a__from [0]
   a__sel1(v0, v1) -> null_a__sel1 [0]
   a__first1(v0, v1) -> null_a__first1 [0]
   a__quote(v0) -> null_a__quote [0]
   a__quote1(v0) -> null_a__quote1 [0]
   a__unquote(v0) -> null_a__unquote [0]
   a__unquote1(v0) -> null_a__unquote1 [0]
   a__fcons(v0, v1) -> null_a__fcons [0]
   mark(v0) -> null_mark [0]

And the following fresh constants:    null_a__sel, null_a__first, null_a__from, null_a__sel1, null_a__first1, null_a__quote, null_a__quote1, null_a__unquote, null_a__unquote1, null_a__fcons, null_mark, const, const1, const2, const3, const4, const5, const6, const7, const8, const9, const10

The TRS is a completely defined constructor system, as every type has a constant constructor and the following rules were added:

   a__sel(v0, v1) -> null_a__sel [0]
   a__first(v0, v1) -> null_a__first [0]
   a__from(v0) -> null_a__from [0]
   a__sel1(v0, v1) -> null_a__sel1 [0]
   a__first1(v0, v1) -> null_a__first1 [0]
   a__quote(v0) -> null_a__quote [0]
   a__quote1(v0) -> null_a__quote1 [0]
   a__unquote(v0) -> null_a__unquote [0]
   a__unquote1(v0) -> null_a__unquote1 [0]
   a__fcons(v0, v1) -> null_a__fcons [0]
   mark(v0) -> null_mark [0]
   A__SEL(v0, v1) -> null_A__SEL [0]
   A__FIRST(v0, v1) -> null_A__FIRST [0]
   A__SEL1(v0, v1) -> null_A__SEL1 [0]
   A__FIRST1(v0, v1) -> null_A__FIRST1 [0]
   A__QUOTE(v0) -> null_A__QUOTE [0]
   A__QUOTE1(v0) -> null_A__QUOTE1 [0]
   A__UNQUOTE(v0) -> null_A__UNQUOTE [0]
   A__UNQUOTE1(v0) -> null_A__UNQUOTE1 [0]
   MARK(v0) -> null_MARK [0]

And the following fresh constants:    null_a__sel, null_a__first, null_a__from, null_a__sel1, null_a__first1, null_a__quote, null_a__quote1, null_a__unquote, null_a__unquote1, null_a__fcons, null_mark, null_A__SEL, null_A__FIRST, null_A__SEL1, null_A__FIRST1, null_A__QUOTE, null_A__QUOTE1, null_A__UNQUOTE, null_A__UNQUOTE1, null_MARK, const, const1
