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