*<del>'''Speedy keep'''</del>, the nominator does not propose a valid [[WP:DEL-REASON]]. The nominator does not say which notability guideline that this article fails to meet. [[User:SailingInABathTub|SailingInABathTub]] ([[User talk:SailingInABathTub|talk]]) 10:18, 13 April 2021 (UTC)
*'''Speedy keep''' all of Coin945's AfDs from today as a procedural matter. Coin945 has nominated ''72'' articles in a short space of time with a questionable rationale ("long-term lack of sourcing" -- see [[WP:NEXIST]]) and no indication of [[WP:BEFORE]], with {{replyto|Uncle G|p=}} finding that a number of them can have their notability confirmed on literally the first page of Google results. This is not something the relatively small group of people who work AfD can realistically handle.

*'''Comment''' We now have a source. However GNG wants us to have multiple sources. Clearly this should not be speedy kept.

*'''Keep but rename''' to [[map-based control]]. This properly belongs as a topic in [[control theory]], not in the theory of lookup tables. Google Scholar has nearly 500 hits for "map-based control", 26 of them in the title. Google Books also has some relevant-looking hits, and there are many others for closely-related phrases such as "map-based ECMS" (one particular application of this technique with over 100 GS hits). There should be plenty of adequate sourcing among them, although the sourcing in the current stub looks adequate for a stub. Although there are also hits for "map-based controller", they are significantly less numerous. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 07:44, 16 April 2021 (UTC)
*:[[User:David Eppstein|David Eppstein]]: but I honestly looked for in-depth coverage, and came up empty. As I said, most papers are devoted to particular applications and take the term for granted. I opened a couple of control theory textbooks at GBooks, expecting a section or a chapter on the topic (looking for "map" or "lookup"), but did not find anything. I'm not an expert in the field, granted, but if after 15 years of existence all that we can say is that there {{tq|should be plenty of adequate sourcing among them}} without anyone finding it, we'd be better off without this article, without prejudice of a recreation. Yes, [[WP:ITEXISTS]], but the current single sentence amounting to a dicdef is not useful for anyone. [[User:No such user|No such user]] ([[User talk:No such user|talk]]) 14:53, 16 April 2021 (UTC)
*'''Keep and rename''', to [[Lookup table-based control system]]. The term [[map-based controller]] is used almost exclusively to describe an [[Engine control unit]], which is an application of a lookup table-based control system. This article uses the name of the former but describes it in the general terms of the latter. I can find [[WP:RS]] for both. There is obviously no point in adding lots of ECU references and ultimately duplicating that article. Here are a bunch of references, to show notability across a range of applications.<ref>{{cite book |url=https://books.google.co.ukcom/books?id=mbMSv8NtuYwC&pg=PA271&lpg=PA271 |title=First Course on Fuzzy Theory and Applications |author=Kwang Hyung Lee |publisher=[[Springer Science & Business Media]] |date=30 November 2006 |page=271|isbn=978-3-540-32366-2 }}</ref><ref>{{cite book |url=https://wwwbooks.google.co.ukcom/books/edition/Classical_and_Modern_Controls_with_Micro/229_DwAAQBAJ?hlid=en&gbpv=1229_DwAAQBAJ&pg=PA454&printsec=frontcover |title=Classical and Modern Controls with Microcontrollers: Design, Implementation and Applications |author1=Ying Bai |author2=Zvi S.
