MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(f(x)) -> f(x)
          f(s(x)) -> f(x)
          g(s(0())) -> g(f(s(0())))
      - 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}
