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