| Jul 28, 2014 at 13:41 | comment | added | Nathaniel Johnston | The question is asking for the best possible upper bound in terms of r, so what is needed is either an example that gets the ratio much larger than 1 (i.e., close to $\sqrt{r}$) or a proof of a better upper bound (e.g., something like $\log(r)$). | |
