 * ... that the name of the Chinese postman problem honors Chinese mathematician Meigu Guan, who first formulated it?

 * Symbol question.svg Interesting article. It's long enough, new enough, and well referenced. No copyvio found. QPQ is done. My main concern is the wording of the hook: the sources only say that the problem is so named because it was formulated by the Chinese mathematician, who called it the postman problem, not in honor of him (at least not explicitly). Also, I suggest using one of the images available on the Commons in the article and the hook, to make it more interesting. -Zanhe (talk) 03:52, 27 April 2016 (UTC)
 * Possibly you're looking at the last page of the Grötschel–Yuan source where it says that Edmonds was the first to use the "Chinese postman" name? But the actual hook source is earlier in the same source (the end of its very first paragraph) where it also says "A young Chinese mathematician was the first to consider an optimization version of Euler’s bridges problem which was later called the Chinese Postman Problem in his honor." As for the images, we don't have any of Guan himself, and unfortunately I don't think the ones you've linked to are intelligible at 100px image size. I did follow your suggestion to add one to the article, though. —David Eppstein (talk) 06:18, 27 April 2016 (UTC)
 * Symbol confirmed.svg Yes I see that now. Hook is verified and good to go. -Zanhe (talk) 23:57, 27 April 2016 (UTC)
