MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(0()) -> 0()
          f(s(x)) -> s(s(f(p(s(x)))))
          p(s(x)) -> x
      - Signature:
          {f/1,p/1} / {0/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,p} and constructors {0,s}
  + Applied Processor:
      NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
