MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(x,h(y)) -> h(f(f(h(a()),y),x))
      - Signature:
          {f/2} / {a/0,h/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f} and constructors {a,h}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
