* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          activate(X) -> X
          activate(n__from(X)) -> from(X)
          from(X) -> cons(X,n__from(s(X)))
          from(X) -> n__from(X)
          sel(0(),cons(X,Y)) -> X
          sel(s(X),cons(Y,Z)) -> sel(X,activate(Z))
      - Signature:
          {activate/1,from/1,sel/2} / {0/0,cons/2,n__from/1,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {activate,from,sel} and constructors {0,cons,n__from,s}
