(1) DecreasingLoopProof (EQUIVALENT transformation)

The following loop(s) give(s) rise to the lower bound Ω(n¹):
The rewrite sequence
sieve(mark(X)) →⁺ mark(sieve(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:
sieve(gen_primes:0':mark:true:false:ok3_0(+(1, n5_0))) → *4_0, rt ∈ Ω(n5₀)

Induction Base:
sieve(gen_primes:0':mark:true:false:ok3_0(+(1, 0)))

Induction Step:
sieve(gen_primes:0':mark:true:false:ok3_0(+(1, +(n5_0, 1)))) →_R^Ω(1)
mark(sieve(gen_primes:0':mark:true:false:ok3_0(+(1, n5_0)))) →_IH
mark(*4_0)

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

(12) RewriteLemmaProof (LOWER BOUND(ID) transformation)

Proved the following rewrite lemma:
from(gen_primes:0':mark:true:false:ok3_0(+(1, n434_0))) → *4_0, rt ∈ Ω(n434₀)

Induction Base:
from(gen_primes:0':mark:true:false:ok3_0(+(1, 0)))

Induction Step:

(33) RewriteLemmaProof (LOWER BOUND(ID) transformation)

Proved the following rewrite lemma:
tail(gen_primes:0':mark:true:false:ok3_0(+(1, n13935_0))) → *4_0, rt ∈ Ω(n13935₀)

Induction Base:
tail(gen_primes:0':mark:true:false:ok3_0(+(1, 0)))

Induction Step:
tail(gen_primes:0':mark:true:false:ok3_0(+(1, +(n13935_0, 1)))) →_R^Ω(1)
mark(tail(gen_primes:0':mark:true:false:ok3_0(+(1, n13935_0)))) →_IH
mark(*4_0)

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