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

and(tt, X) → activate(X)
plus(N, 0) → N
plus(N, s(M)) → s(plus(N, M))
activate(X) → X

Rewrite Strategy: INNERMOST

Renamed function symbols to avoid clashes with predefined symbol.

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


and'(tt', X) → activate'(X)

Rules:

Types:

The following defined symbols remain to be analysed:
plus'

Proved the following rewrite lemma:
plus'(_gen_0':s'4(a), _gen_0':s'4(_n6)) → _gen_0':s'4(+(_n6, a)), rt ∈ Ω(1 + n6)

Induction Base:
plus'(_gen_0':s'4(a), _gen_0':s'4(0)) →RΩ(1)
_gen_0':s'4(a)

Induction Step:
plus'(_gen_0':s'4(_a139), _gen_0':s'4(+(_$n7, 1))) →RΩ(1)
s'(plus'(_gen_0':s'4(_a139), _gen_0':s'4(_$n7))) →IH
s'(_gen_0':s'4(+(_$n7, _a139)))

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

Lemmas:
plus'(_gen_0':s'4(a), _gen_0':s'4(_n6)) → _gen_0':s'4(+(_n6, a)), rt ∈ Ω(1 + n6)

No more defined symbols left to analyse.

The lowerbound Ω(n) was proven with the following lemma:
