* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          rev(++(x,y)) -> ++(rev1(x,y),rev2(x,y))
          rev(nil()) -> nil()
          rev1(x,++(y,z)) -> rev1(y,z)
          rev1(x,nil()) -> x
          rev2(x,++(y,z)) -> rev(++(x,rev(rev2(y,z))))
          rev2(x,nil()) -> nil()
      - Signature:
          {rev/1,rev1/2,rev2/2} / {++/2,nil/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {rev,rev1,rev2} and constructors {++,nil}
  + Applied Processor:
      Ara {heuristics_ = NoHeuristics, minDegree = 1, maxDegree = 3, araTimeout = 60, araFindStrictRules = Nothing, araSmtSolver = MiniSMT}
  + Details:
      The input can not be schown compatible.
