It is nowadays pretty standard to have a DOI with every item-to-be-cited (papers, algorithms, data, etc.), and they are really useful for all kinds of purposes. Considering this, I am quite surprised to be unable to find DOIs for NeurIPS papers, especially considering that it is one of the major CS conferences... Is there a reason for this?
Related question: Why do some papers not have a DOI? The highest voted answer there relates to the time/cost required to obtain a DOI, both of which I would assume not to be an issue for NeurIPS...
