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

   active(nats) -> mark(cons(0, incr(nats)))
   active(pairs) -> mark(cons(0, incr(odds)))
   active(odds) -> mark(incr(pairs))
   active(incr(cons(X, XS))) -> mark(cons(s(X), incr(XS)))
   active(head(cons(X, XS))) -> mark(X)
   active(tail(cons(X, XS))) -> mark(XS)
   active(cons(X1, X2)) -> cons(active(X1), X2)
   active(incr(X)) -> incr(active(X))
   active(s(X)) -> s(active(X))
   active(head(X)) -> head(active(X))
   active(tail(X)) -> tail(active(X))
   cons(mark(X1), X2) -> mark(cons(X1, X2))
   incr(mark(X)) -> mark(incr(X))
   s(mark(X)) -> mark(s(X))
   head(mark(X)) -> mark(head(X))
   tail(mark(X)) -> mark(tail(X))
   proper(nats) -> ok(nats)
   proper(cons(X1, X2)) -> cons(proper(X1), proper(X2))
   proper(0) -> ok(0)
   proper(incr(X)) -> incr(proper(X))
   proper(pairs) -> ok(pairs)
   proper(odds) -> ok(odds)
   proper(s(X)) -> s(proper(X))
   proper(head(X)) -> head(proper(X))
   proper(tail(X)) -> tail(proper(X))
   cons(ok(X1), ok(X2)) -> ok(cons(X1, X2))
   incr(ok(X)) -> ok(incr(X))
   s(ok(X)) -> ok(s(X))
   head(ok(X)) -> ok(head(X))
   tail(ok(X)) -> ok(tail(X))
   top(mark(X)) -> top(proper(X))
   top(ok(X)) -> top(active(X))

The set Q consists of the following terms:

   active(nats)
   active(pairs)
   active(odds)
   active(cons(x0, x1))
   active(incr(x0))
   active(s(x0))
   active(head(x0))
   active(tail(x0))
   cons(mark(x0), x1)
   incr(mark(x0))
   s(mark(x0))
   head(mark(x0))
   tail(mark(x0))
   proper(nats)
   proper(cons(x0, x1))
   proper(0)
   proper(incr(x0))
   proper(pairs)
   proper(odds)
   proper(s(x0))
   proper(head(x0))
   proper(tail(x0))
   cons(ok(x0), ok(x1))
   incr(ok(x0))
   s(ok(x0))
   head(ok(x0))
   tail(ok(x0))
   top(mark(x0))
   top(ok(x0))
