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

f(0) → cons(0, n__f(s(0)))
f(s(0)) → f(p(s(0)))
p(s(0)) → 0
f(X) → n__f(X)
activate(n__f(X)) → f(X)
activate(X) → X

(5) CdtPolyRedPairProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

F(s(0)) → c1(F(p(s(0))), P(s(0)))
We considered the (Usable) Rules:

p(s(0)) → 0
And the Tuples:

F(s(0)) → c1(F(p(s(0))), P(s(0)))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(0) = [4]   
POL(F(x1)) = [4]x1   
POL(P(x1)) = [4] + x1   
POL(c1(x1, x2)) = x1 + x2   
POL(p(x1)) = [4]   
POL(s(x1)) = [5] + x1
