(15) 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:

   COND_3
   GR_2

(c) The following functions are completely defined:

   gr_2
   p_1

Due to the following rules being added:

   gr(v0, v1) -> null_gr [0]
   p(v0) -> 0 [0]

And the following fresh constants:    null_gr, const, const1

(61) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
gr(gen_s:0'8_7(n11_7), gen_s:0'8_7(n11_7)) -> false, rt in Omega(0)

Induction Base:
gr(gen_s:0'8_7(0), gen_s:0'8_7(0)) ->_R^Omega(0)
false

Induction Step:
gr(gen_s:0'8_7(+(n11_7, 1)), gen_s:0'8_7(+(n11_7, 1))) ->_R^Omega(0)
gr(gen_s:0'8_7(n11_7), gen_s:0'8_7(n11_7)) ->_IH
false

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