MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(x) -> f(a())
      - Signature:
          {f/1} / {a/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f} and constructors {a}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
