I know that arxiv is sufficient, but I was hoping for some social media like platform that offers the same functionality for articles that besides the mathematical content also some explanations or context that is aimed at a broader audience.
@dbal thanks for the hint to the trees; I think that generalizes to an O(n) algorithm for cycles; if we duplicate say vertex 0 an make that the start and lend of a path, the we can have three cases: a) the first edge but not the last edge is in the matching; b) the last but not the first edge is in the matching; c) neither the first nor the last edge is in the matching.
How "safe" is it to blog on mathstodon in the sense that contributions are time-stamped and versioned so that potential disputes about priority in having solved a problem can be settled easily by means of those time-stamps? What about the longevity of the platform; are there plans for migration to another host or will it eventually be "torn down"?
@PiotrHajlasz I agree with you, many first time publishers will attempt to get something accepted on arXiv and would likely appreciate some advice on how to get the basic precondition, namely the writing style, right. If the paper on writing papers were accompnied with some tex templates then that would be really great
Loops in the sense of directed Hamilton cycles are allowed; ruling them out would be unnatural and allowing them makes it possible to develop heuristics for ATSPs that start from a greedily constructed directed tree.
