Q restricted rewrite system:
The TRS R consists of the following rules:

   active(filter(cons(X, Y), 0, M)) -> mark(cons(0, filter(Y, M, M)))
   active(filter(cons(X, Y), s(N), M)) -> mark(cons(X, filter(Y, N, M)))
   active(sieve(cons(0, Y))) -> mark(cons(0, sieve(Y)))
   active(sieve(cons(s(N), Y))) -> mark(cons(s(N), sieve(filter(Y, N, N))))
   active(nats(N)) -> mark(cons(N, nats(s(N))))
   active(zprimes) -> mark(sieve(nats(s(s(0)))))
   active(filter(X1, X2, X3)) -> filter(active(X1), X2, X3)
   active(filter(X1, X2, X3)) -> filter(X1, active(X2), X3)
   active(filter(X1, X2, X3)) -> filter(X1, X2, active(X3))
   active(cons(X1, X2)) -> cons(active(X1), X2)
   active(s(X)) -> s(active(X))
   active(sieve(X)) -> sieve(active(X))
   active(nats(X)) -> nats(active(X))
   filter(mark(X1), X2, X3) -> mark(filter(X1, X2, X3))
   filter(X1, mark(X2), X3) -> mark(filter(X1, X2, X3))
   filter(X1, X2, mark(X3)) -> mark(filter(X1, X2, X3))
   cons(mark(X1), X2) -> mark(cons(X1, X2))
   s(mark(X)) -> mark(s(X))
   sieve(mark(X)) -> mark(sieve(X))
   nats(mark(X)) -> mark(nats(X))
   proper(filter(X1, X2, X3)) -> filter(proper(X1), proper(X2), proper(X3))
   proper(cons(X1, X2)) -> cons(proper(X1), proper(X2))
   proper(0) -> ok(0)
   proper(s(X)) -> s(proper(X))
   proper(sieve(X)) -> sieve(proper(X))
   proper(nats(X)) -> nats(proper(X))
   proper(zprimes) -> ok(zprimes)
   filter(ok(X1), ok(X2), ok(X3)) -> ok(filter(X1, X2, X3))
   cons(ok(X1), ok(X2)) -> ok(cons(X1, X2))
   s(ok(X)) -> ok(s(X))
   sieve(ok(X)) -> ok(sieve(X))
   nats(ok(X)) -> ok(nats(X))
   top(mark(X)) -> top(proper(X))
   top(ok(X)) -> top(active(X))

The set Q consists of the following terms:

   active(nats(x0))
   active(zprimes)
   active(filter(x0, x1, x2))
   active(cons(x0, x1))
   active(s(x0))
   active(sieve(x0))
   filter(mark(x0), x1, x2)
   filter(x0, mark(x1), x2)
   filter(x0, x1, mark(x2))
   cons(mark(x0), x1)
   s(mark(x0))
   sieve(mark(x0))
   nats(mark(x0))
   proper(filter(x0, x1, x2))
   proper(cons(x0, x1))
   proper(0)
   proper(s(x0))
   proper(sieve(x0))
   proper(nats(x0))
   proper(zprimes)
   filter(ok(x0), ok(x1), ok(x2))
   cons(ok(x0), ok(x1))
   s(ok(x0))
   sieve(ok(x0))
   nats(ok(x0))
   top(mark(x0))
   top(ok(x0))
