(1) DecreasingLoopProof (EQUIVALENT transformation)
The following loop(s) give(s) rise to the lower bound Ω(n1):
The rewrite sequence
+(s(x), y) →+ s(+(x, y))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0].
The pumping substitution is [x / s(x)].
The result substitution is [ ].

(23) RewriteLemmaProof (LOWER BOUND(ID) transformation)
Proved the following rewrite lemma:
length(
gen_nil::4_0(
n2660_0)) →
gen_0':s3_0(
n2660_0), rt ∈ Ω(1 + n2660
0)
Induction Base:
length(gen_nil::4_0(0)) →RΩ(1)
0'
Induction Step:
length(gen_nil::4_0(+(n2660_0, 1))) →RΩ(1)
s(length(gen_nil::4_0(n2660_0))) →IH
s(gen_0':s3_0(c2661_0))
We have rt ∈ Ω(n1) and sz ∈ O(n). Thus, we have ircR ∈ Ω(n).
