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