Runtime Complexity TRS:
The TRS R consists of the following rules:

D(t) → 1
D(constant) → 0
D(+(x, y)) → +(D(x), D(y))
D(*(x, y)) → +(*(y, D(x)), *(x, D(y)))
D(-(x, y)) → -(D(x), D(y))

Rewrite Strategy: INNERMOST

(1) RenamingProof (EQUIVALENT transformation)

(7) RewriteLemmaProof (LOWER BOUND(ID) transformation)

Proved the following rewrite lemma:
D(gen_t:1':constant:0':+':*':-2_0(n4_0)) → *3_0, rt ∈ Ω(n40)

Induction Base:
D(gen_t:1':constant:0':+':*':-2_0(0))

Induction Step:
D(gen_t:1':constant:0':+':*':-2_0(+(n4_0, 1))) →RΩ(1)
+'(D(t), D(gen_t:1':constant:0':+':*':-2_0(n4_0))) →RΩ(1)
+'(1', D(gen_t:1':constant:0':+':*':-2_0(n4_0))) →IH
+'(1', *3_0)

We have rt ∈ Ω(n1) and sz ∈ O(n). Thus, we have ircR ∈ Ω(n).
