MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(x,0()) -> s(0())
          f(s(x),s(y)) -> s(f(x,y))
          g(0(),x) -> g(f(x,x),x)
      - Signature:
          {f/2,g/2} / {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}
