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:

   COND1_2
   COND2_2
   EVEN_1
   DIV2_1

(c) The following functions are completely defined:

   even_1
   neq_2
   div2_1
   p_1

Due to the following rules being added:

   even(v0) -> null_even [0]
   neq(v0, v1) -> null_neq [0]
   div2(v0) -> 0 [0]
   p(v0) -> 0 [0]

And the following fresh constants:    null_even, null_neq, const, const1, const2, const3

(79) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
even(gen_0':s:y10_17(*(2, n15_17))) -> true, rt in Omega(0)

Induction Base:
even(gen_0':s:y10_17(*(2, 0))) ->_R^Omega(0)
true

Induction Step:
even(gen_0':s:y10_17(*(2, +(n15_17, 1)))) ->_R^Omega(0)
even(gen_0':s:y10_17(*(2, n15_17))) ->_IH
true

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

(87) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:
div2(gen_0':s:y10_17(*(2, n779_17))) -> gen_0':s:y10_17(n779_17), rt in Omega(0)

Induction Base:
div2(gen_0':s:y10_17(*(2, 0))) ->_R^Omega(0)
0'

Induction Step:
div2(gen_0':s:y10_17(*(2, +(n779_17, 1)))) ->_R^Omega(0)
s(div2(gen_0':s:y10_17(*(2, n779_17)))) ->_IH
s(gen_0':s:y10_17(c780_17))

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