The reviewers uniformly agreed that this is a well-written paper, on an important problem, describing a novel approach, with a good experimental evaluation. Most of their remaining concerns appear to require relatively minor changes. Of these, the most significant are (i) missing related work (R5 included some potential citations), (ii) an unclear explanation of Table 5, and (iii) that R(f) is estimated from samples, but this isn’t made clear in the main text (instead of the appendix). Overall, this is a solid paper, and a few tweaks would make it even better. Please carefully read the reviews, and take their suggestions seriously when making edits.
