Thanks! I agree with you.  But, If the authors want to offer co-authorship, how can they do so? They do not know my name and I also do not their names.

In a journal, the communication is through the editor. At a conference it’s trickier but presumably the Area Chair can mediate.

I like the flowchart, but some comments: "just" a few days may be already a long time in case of conferences were you rarely have more than a month. Also, I would personnally add an extra layer before the last no: "do you think this is a good enough contribution for a whole new paper / do you plan to work on this subject". I often find non trivial simplifications of proofs in papers I am reviewing and often give it to the authors because I do not have time/energy to write an incremental version of the paper later. And contributions done in a few days are rarely *that* interesting.

@holf Good point about contributions that are too small for a new paper and which you don't have any plans to expand on. I'm not sure what should really be done with such ideas. If they don't fit into the current paper, the authors may not gain any benefits from them. On the other hand, it never hurts and they might get inspired.

This seems like an excellent answer, I suspect that there are some similar questions on the AcademiaSE that would also benefit from this flowchart!

I'm not sure there's a meaningful distinction between, say, finding a mistake in a proof or suggesting a considerable simplification and "original research"; both of the former could, under appropriate circumstances, be publishable as such.

Write a paper about the general instance of the problem to showcase your solution.

This can work *only* after publishing their paper first. And sometimes at AI conferences like AAAI/IJCAI you need to wait a couple of months after the paper appears.

# Reviewing a paper and found a better solution

(Asked by: username_0 on 2021-07-11)

I was reviewing a paper of a double-blind conference (ML/AI-based conference). The authors improved the approximation bounds for some *special* instances of a problem.
To understand their proof better, I was thinking of a solution by myself while picking some hints from their proof. Using those hints, I came up with a better algorithm for the general instance of the problem. Moreover, my algorithm is much simpler than theirs.

I am feeling a bit greedy here; I want to suggest these changes to them and also want authorship in their paper. I can not ask them since I do not know them. I can not publish my own paper since a few ideas are borrowed from their proof and their manuscript is not online. What should I do?

I don’t think there’s a clear protocol. I’ve seen referees generously offer improvements. I’ve seen authors offer coauthorship for those improvements. I’ve seen the referee accept or decline the offer.

Of course, it’s perfectly legitimate for you to wait for them to publish and then submit your improvement. Delaying by a few months is a gamble (might get scooped, including by the authors). But the preceding options involve gambles as well.
