* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          activate(X) -> X
          activate(n__cons(X1,X2)) -> cons(activate(X1),X2)
          activate(n__from(X)) -> from(activate(X))
          activate(n__nil()) -> nil()
          activate(n__s(X)) -> s(activate(X))
          cons(X1,X2) -> n__cons(X1,X2)
          from(X) -> cons(X,n__from(n__s(X)))
          from(X) -> n__from(X)
          length(n__cons(X,Y)) -> s(length1(activate(Y)))
          length(n__nil()) -> 0()
          length1(X) -> length(activate(X))
          nil() -> n__nil()
          s(X) -> n__s(X)
      - Signature:
          {activate/1,cons/2,from/1,length/1,length1/1,nil/0,s/1} / {0/0,n__cons/2,n__from/1,n__nil/0,n__s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {activate,cons,from,length,length1,nil
          ,s} and constructors {0,n__cons,n__from,n__nil,n__s}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
