Notability?

Why does this have its own Wiki article? Is there some other article this can be merged to? I just don't see how this concept warrants an article. Torc2 (talk) 23:03, 28 November 2007 (UTC)[reply]

scholar.google.com lists 908 scientific articles mentioning Feedback Vertex Set; 88 have it in their title. It would be easy to fill a whole book with the results. So in my opinion, this concepts does warrant an article. --Mellum (talk) 23:28, 29 November 2007 (UTC)[reply]

OK, I was just legitimately curious - I didn't tag it or nominate it for deletion. It'd be nice to flesh out the section on uses for the function. Torc2 (talk) 23:42, 29 November 2007 (UTC)[reply]

Statement removed from main article

I have removed the following sentence from the main article:

In contrast, the problem is polynomial-time solvable on graphs of maximum degree at most three.^{[citation needed]}

This statement was initially sourced Cao, Chen & Liu (2010), but is not supported by that reference. Hermel (talk) 19:35, 27 October 2011 (UTC)[reply]

NP-hard vs NP-complete

The article keeps saying that the optimization version (MINIMUM FVS) is NP-complete. It is not. It is NP-hard. It is the decision problem that is NP-complete.

This is probably happening in other articles as well. 68.5.117.23 (talk) 01:21, 15 July 2022 (UTC)[reply]

This likely does happen in other articles, but shouldn't be a problem any more in this one. 2603:8001:3D00:6BD:E199:A58B:72C0:97CF (talk) 01:31, 19 April 2025 (UTC)[reply]
