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