(13) OrderProof (LOWER BOUND(ID))
Heuristically decided to analyse the following defined symbols:
A__SEL, MARK, mark, A__DBL1, A__SEL1, A__QUOTE, a__sel, a__dbl1, a__sel1, a__quote

They will be analysed ascendingly in the following order:
A__SEL = MARK
mark < A__SEL
A__SEL = A__DBL1
A__SEL = A__SEL1
A__SEL = A__QUOTE
mark < MARK
MARK = A__DBL1
MARK = A__SEL1
MARK = A__QUOTE
mark < A__DBL1
mark < A__SEL1
mark < A__QUOTE
mark = a__sel
mark = a__dbl1
mark = a__sel1
mark = a__quote
A__DBL1 = A__SEL1
A__DBL1 = A__QUOTE
A__SEL1 = A__QUOTE
a__sel = a__dbl1
a__sel = a__sel1
a__sel = a__quote
a__dbl1 = a__sel1
a__dbl1 = a__quote
a__sel1 = a__quote

The following defined symbols remain to be analysed:
a__sel, A__SEL, MARK, mark, A__DBL1, A__SEL1, A__QUOTE, a__dbl1, a__sel1, a__quote

They will be analysed ascendingly in the following order:
A__SEL = MARK
mark < A__SEL
A__SEL = A__DBL1
A__SEL = A__SEL1
A__SEL = A__QUOTE
mark < MARK
MARK = A__DBL1
MARK = A__SEL1
MARK = A__QUOTE
mark < A__DBL1
mark < A__SEL1
mark < A__QUOTE
mark = a__sel
mark = a__dbl1
mark = a__sel1
mark = a__quote
A__DBL1 = A__SEL1
A__DBL1 = A__QUOTE
A__SEL1 = A__QUOTE
a__sel = a__dbl1
a__sel = a__sel1
a__sel = a__quote
a__dbl1 = a__sel1
a__dbl1 = a__quote
a__sel1 = a__quote

(15) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n79128_44))) -> *17_44, rt in Omega(0)

Induction Base:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, 0)))

Induction Step:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, +(n79128_44, 1)))) ->_R^Omega(0)
s1(s1(a__dbl1(mark(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n79128_44)))))) ->_R^Omega(0)
s1(s1(a__dbl1(s(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(n79128_44))))) ->_IH
s1(s1(*17_44))

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

The following defined symbols remain to be analysed:
a__sel1, A__SEL, MARK, mark, A__DBL1, A__SEL1, A__QUOTE, a__sel, a__quote

They will be analysed ascendingly in the following order:
A__SEL = MARK
mark < A__SEL
A__SEL = A__DBL1
A__SEL = A__SEL1
A__SEL = A__QUOTE
mark < MARK
MARK = A__DBL1
MARK = A__SEL1
MARK = A__QUOTE
mark < A__DBL1
mark < A__SEL1
mark < A__QUOTE
mark = a__sel
mark = a__dbl1
mark = a__sel1
mark = a__quote
A__DBL1 = A__SEL1
A__DBL1 = A__QUOTE
A__SEL1 = A__QUOTE
a__sel = a__dbl1
a__sel = a__sel1
a__sel = a__quote
a__dbl1 = a__sel1
a__dbl1 = a__quote
a__sel1 = a__quote

(17) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
a__quote(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n1978599_44))) -> *17_44, rt in Omega(0)

Induction Base:
a__quote(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, 0)))

Induction Step:
a__quote(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, +(n1978599_44, 1)))) ->_R^Omega(0)
s1(a__quote(mark(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n1978599_44))))) ->_R^Omega(0)
s1(a__quote(s(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(n1978599_44)))) ->_IH
s1(*17_44)

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

The following defined symbols remain to be analysed:
a__sel, A__SEL, MARK, mark, A__DBL1, A__SEL1, A__QUOTE, a__dbl1, a__sel1

They will be analysed ascendingly in the following order:
A__SEL = MARK
mark < A__SEL
A__SEL = A__DBL1
A__SEL = A__SEL1
A__SEL = A__QUOTE
mark < MARK
MARK = A__DBL1
MARK = A__SEL1
MARK = A__QUOTE
mark < A__DBL1
mark < A__SEL1
mark < A__QUOTE
mark = a__sel
mark = a__dbl1
mark = a__sel1
mark = a__quote
A__DBL1 = A__SEL1
A__DBL1 = A__QUOTE
A__SEL1 = A__QUOTE
a__sel = a__dbl1
a__sel = a__sel1
a__sel = a__quote
a__dbl1 = a__sel1
a__dbl1 = a__quote
a__sel1 = a__quote

(19) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n3959707_44))) -> *17_44, rt in Omega(0)

Induction Base:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, 0)))

Induction Step:
a__dbl1(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, +(n3959707_44, 1)))) ->_R^Omega(0)
s1(s1(a__dbl1(mark(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(+(1, n3959707_44)))))) ->_R^Omega(0)
s1(s1(a__dbl1(s(gen_0':s:nil:cons:dbl:sel:dbls:indx:from:dbl1:sel1:quote:01':s111_44(n3959707_44))))) ->_IH
s1(s1(*17_44))

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

(31) CompletionProof (UPPER BOUND(ID))
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:
none

(c) The following functions are completely defined:

   mark_1
   a__indx_2
   a__sel1_2
   a__dbls_1
   a__quote_1
   a__dbl1_1
   a__sel_2
   a__from_1
   a__dbl_1

Due to the following rules being added:
none

And the following fresh constants: none

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

(55) CompletionProof (UPPER BOUND(ID))
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__DBL1_1
   A__SEL1_2
   A__QUOTE_1
   MARK_1

(c) The following functions are completely defined:

   a__dbl_1
   a__dbls_1
   a__sel_2
   a__indx_2
   a__from_1
   a__dbl1_1
   a__sel1_2
   a__quote_1
   mark_1

Due to the following rules being added:

   a__dbl(v0) -> null_a__dbl [0]
   a__dbls(v0) -> null_a__dbls [0]
   a__sel(v0, v1) -> null_a__sel [0]
   a__indx(v0, v1) -> null_a__indx [0]
   a__from(v0) -> null_a__from [0]
   a__dbl1(v0) -> null_a__dbl1 [0]
   a__sel1(v0, v1) -> null_a__sel1 [0]
   a__quote(v0) -> null_a__quote [0]
   mark(v0) -> null_mark [0]

And the following fresh constants:    null_a__dbl, null_a__dbls, null_a__sel, null_a__indx, null_a__from, null_a__dbl1, null_a__sel1, null_a__quote, null_mark, const, const1, const2, const3, const4

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

   0 => 0
   nil => 2
   01 => 1
   null_a__dbl => 0
   null_a__dbls => 0
   null_a__sel => 0

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

   a__dbl(v0) -> null_a__dbl [0]
   a__dbls(v0) -> null_a__dbls [0]
   a__sel(v0, v1) -> null_a__sel [0]
   a__indx(v0, v1) -> null_a__indx [0]
   a__from(v0) -> null_a__from [0]
   a__dbl1(v0) -> null_a__dbl1 [0]
   a__sel1(v0, v1) -> null_a__sel1 [0]
   a__quote(v0) -> null_a__quote [0]
   mark(v0) -> null_mark [0]
   A__SEL(v0, v1) -> null_A__SEL [0]
   A__DBL1(v0) -> null_A__DBL1 [0]
   A__SEL1(v0, v1) -> null_A__SEL1 [0]
   A__QUOTE(v0) -> null_A__QUOTE [0]
   MARK(v0) -> null_MARK [0]

And the following fresh constants:    null_a__dbl, null_a__dbls, null_a__sel, null_a__indx, null_a__from, null_a__dbl1, null_a__sel1, null_a__quote, null_mark, null_A__SEL, null_A__DBL1, null_A__SEL1, null_A__QUOTE, null_MARK
