MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          aver(sum,z) -> if(gt(sum,double(z)),sum,z)
          average(x,y) -> aver(plus(x,y),0())
          double(0()) -> 0()
          double(s(x)) -> s(s(double(x)))
          gt(0(),y) -> false()
          gt(s(x),0()) -> true()
          gt(s(x),s(y)) -> gt(x,y)
          if(false(),sum,z) -> z
          if(true(),sum,z) -> aver(sum,s(z))
          plus(0(),y) -> y
          plus(s(x),y) -> s(plus(x,y))
      - Signature:
          {aver/2,average/2,double/1,gt/2,if/3,plus/2} / {0/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {aver,average,double,gt,if,plus} and constructors {0,false
          ,s,true}
  + Applied Processor:
      Ara {heuristics_ = NoHeuristics, minDegree = 1, maxDegree = 3, araTimeout = 60, araFindStrictRules = Nothing, araSmtSolver = Z3}
  + Details:
      The input can not be schown compatible.
