Talk:OPTICS algorithm

Pseudocode
The pseudocode in the article contains sentence "output p to the ordered list". Does the ordered list means a cluster? — Preceding unsigned comment added by 158.193.100.8 (talk) 18:49, 7 November 2018 (UTC)

 * Done: DOI given by Springer was for the whole book, not just the chapter. Manual "cite book" now. --Chire2 (talk) 11:47, 4 May 2010 (UTC)

Is there anybody who could understand the essence of the algorithm with help of the explanation given in this article?

Is the algorithm correct?
At no point in the algorithm is the property core-distance actually set to a non-undefined value. suggests that this should happen when the seed-points are marked as processed. (i.e. after "mark q as processed") — Preceding unsigned comment added by Completely unique username (talk • contribs) 16:20, 5 February 2016 (UTC)


 * The function core-distance(q, eps, Minpts) can return UNDEFINED. It is not given in pseudo-code. Chire (talk) 12:35, 8 February 2016 (UTC)
