* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          activate(X) -> X
          activate(n__f(X)) -> f(X)
          f(X) -> n__f(X)
          f(0()) -> cons(0(),n__f(s(0())))
          f(s(0())) -> f(p(s(0())))
          p(s(X)) -> X
      - Signature:
          {activate/1,f/1,p/1} / {0/0,cons/2,n__f/1,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {activate,f,p} and constructors {0,cons,n__f,s}
