  + Considered Problem:
      - Strict TRS:
          activate(X) -> X
          activate(n__filter(X1,X2,X3)) -> filter(activate(X1),activate(X2),activate(X3))
          activate(n__nats(X)) -> nats(activate(X))
          activate(n__s(X)) -> s(activate(X))
          activate(n__sieve(X)) -> sieve(activate(X))
          filter(X1,X2,X3) -> n__filter(X1,X2,X3)
          filter(cons(X,Y),0(),M) -> cons(0(),n__filter(activate(Y),M,M))
          filter(cons(X,Y),s(N),M) -> cons(X,n__filter(activate(Y),N,M))
          nats(N) -> cons(N,n__nats(n__s(N)))
          nats(X) -> n__nats(X)
          s(X) -> n__s(X)
          sieve(X) -> n__sieve(X)
          sieve(cons(0(),Y)) -> cons(0(),n__sieve(activate(Y)))
          sieve(cons(s(N),Y)) -> cons(s(N),n__sieve(n__filter(activate(Y),N,N)))
          zprimes() -> sieve(nats(s(s(0()))))
      - Signature:
          {activate/1,filter/3,nats/1,s/1,sieve/1,zprimes/0} / {0/0,cons/2,n__filter/3,n__nats/1,n__s/1,n__sieve/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {activate,filter,nats,s,sieve,zprimes} and constructors {0
          ,cons,n__filter,n__nats,n__s,n__sieve}
