Post-2016 Register census entry 150
A post-2016 Register census entry for a claimed P = NP result by Xinyi Zhou. It was not part of Woeginger’s frozen list and remains an unadjudicated candidate.
The Register publishes this census record without endorsing or adjudicating the mathematical claim.
Unadjudicated does not mean endorsed.
No refutation is recorded in the census data. Absence of a located response is not evidence that none exists.
A dated, persistent repository record in the window explicitly announces a P=NP proof; unlike a personal post, it is admitted to the candidate file for review.
The same link-list treatment is used across both corpora. These 63 post-2016 URLs carry the census’s dated link state; the 45-of-174 link-rot statistic remains explicitly historical.
