Quote_notation: overly optimistic

The article on "Quote_notation", although sort of interesting, is overly optimistic on the usefulness of this notation for general computation with fractions. There is an obvious problem that the length of a quote notated fraction is linear in its denominator, often even close to it.

This optimism is already there in the original article.

For example, the suggestion is that subtraction of two quote notated number is "just subtract". Here a bad counterexample: To subtract 1/19 from 1/17 (giving 2/323), you compute 2941176470588235'3 - 894736842105263159'9, and after subtraction you get a number with a repeating part of 144 digits, ending in ...4334365325077'4

This is not easy by any stretch of the imagination. However, the notation is still an interesting thought experiment, so I would suggest not to remove it, but just make it a bit more realistic.

Recent proof attempt of P?NP

I'd like to draw your attention to this edit: recently, a paper has been published claiming to prove P?NP. If the proof turned out to be unflawed, we'd have to change "unless P=NP" to "since P?NP" (or similar) in a lot of articles. According to the cited blog, the paper will (have) be(en) discussed in this Oberwolfach Workshop (13-19 Aug). - Jochen Burghardt (talk) 04:43, 26 August 2017 (UTC)

ISO 4 redirects help!

{{Infobox journal}} now features ISO 4 redirect detection to help with the creation and maintenance of these redirects, and will populate Category:Articles with missing ISO 4 redirects. ISO 4 redirects help readers find journal articles based on their official ISO abbreviations (e.g. J. Phys. A -> Journal of Physics A), and also help with compilations like WP:JCW and WP:JCW/TAR.

The category is populated by the |abbreviation= parameter of {{Infobox journal}}. If you're interested in created missing ISO 4 redirects

• Load up an article from the category (or only check for e.g. Computer science journals).
• One or more maintenance templates should be at the top of page, with links to create the relevant redirects and verify the abbreviations.
• VERIFY THAT THE ABBREVIATION IN |abbreviation= IS CORRECT FIRST

• Use the link in the maintenance template to create the redirects and automatically tag them with {{R from ISO 4}}.
• WP:NULL/WP:PURGE the original article to remove the maintenance templates.
