(9) RewriteLemmaProof (LOWER BOUND(ID) transformation)
Proved the following rewrite lemma:
r1(
gen_empty:cons2_0(
n4_0),
gen_empty:cons2_0(
b)) →
gen_empty:cons2_0(
+(
n4_0,
b)), rt ∈ Ω(1 + n4
0)
Induction Base:
r1(gen_empty:cons2_0(0), gen_empty:cons2_0(b)) →RΩ(1)
gen_empty:cons2_0(b)
Induction Step:
r1(gen_empty:cons2_0(+(n4_0, 1)), gen_empty:cons2_0(b)) →RΩ(1)
r1(gen_empty:cons2_0(n4_0), cons(gen_empty:cons2_0(b))) →IH
gen_empty:cons2_0(+(+(b, 1), c5_0))
We have rt ∈ Ω(n1) and sz ∈ O(n). Thus, we have ircR ∈ Ω(n).
