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

(9) RewriteLemmaProof (LOWER BOUND(ID) transformation)
Proved the following rewrite lemma:
f(
gen_a:mark:ok3_0(
+(
1,
n5_0))) →
*4_0, rt ∈ Ω(n5
0)
Induction Base:
f(gen_a:mark:ok3_0(+(1, 0)))
Induction Step:
f(gen_a:mark:ok3_0(+(1, +(n5_0, 1)))) →RΩ(1)
mark(f(gen_a:mark:ok3_0(+(1, n5_0)))) →IH
mark(*4_0)
We have rt ∈ Ω(n1) and sz ∈ O(n). Thus, we have ircR ∈ Ω(n).
