(0) Obligation:

The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(1, n^2).

The TRS R consists of the following rules:

cond(true, x) → cond(and(even(x), gr(x, 0)), p(x))
and(x, false) → false
and(false, x) → false
and(true, true) → true
even(0) → true
even(s(0)) → false
even(s(s(x))) → even(x)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
p(0) → 0
p(s(x)) → x

(5) CompletionProof (UPPER BOUND(ID) transformation)

The transformation into a RNTS is sound, since:

(a) The obligation is a constructor system where every type has a constant constructor,

(b) The following defined symbols do not have to be completely defined, as they can never occur inside other defined symbols:

cond

and
even
gr
p

Due to the following rules being added:

even(v0) → null_even [0]
gr(v0, v1) → null_gr [0]
p(v0) → null_p [0]
and(v0, v1) → null_and [0]

And the following fresh constants:

null_even, null_gr, null_p, null_and, const

(6) Obligation:

even(v0) → null_even [0]
gr(v0, v1) → null_gr [0]
p(v0) → null_p [0]
