MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(s(x),x) -> f(s(x),round(s(x)))
          round(0()) -> 0()
          round(0()) -> s(0())
          round(s(0())) -> s(0())
          round(s(s(x))) -> s(s(round(x)))
      - Signature:
          {f/2,round/1} / {0/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,round} and constructors {0,s}
