 * Suspected sockpuppets

Other users who have also made long series of contributions to these articles but don't quite seem to fit the same pattern:


 * User compare report Auto-generated every hour.
 * Editor interaction utility

These single-purpose-accounts, many with Indian names, have been making long sequences of edits to articles on specialized variants of graph coloring (particularly star coloring, total coloring, acyclic coloring, harmonious coloring, path coloring, incidence coloring, interval edge coloring, radio coloring, and the now-deleted foundational-copyvio articles sum coloring and SUM coloring). Typical editing characteristics include (1) each editor will primarily edit only one article, (2) many consecutive edits to the same article, (3) few or no edit summaries, (4) occasional additions of images and see-also links, and (5) frequent plagiarism from multiple academic papers on these subjects. It got tedious to list all the instances of these, but here are a few representative examples:
 * Tenzin tsetan resur (the namesake of this case because this seems to be the oldest account, with some minor vandalism to an unrelated article before this whole mess really started), Total coloring, 5 consecutive edits, copyvio of "Total Coloring and Total Coloring of Thorny Graphs" by Yorgancioglu and Dundar: ; Total coloring, 4 edits, interrupted by an anon change of image, copyvio of "Fuzzy total coloring of fuzzy graphs" by Lavanya and Sattanathan (which it cites with Bruce Reed listed as an extra author):
 * Oliver drishila, L(h, k)-coloring, 9 consecutive edits, copyvio of "Full color theorems for L (2, 1)-colorings" by Fishburn and Roberts:
 * Anjali.jeraldin, Acyclic coloring, 6 consecutive edits (interrupted by two minor edits), copyvio of "Exact algorithms for coloring graphs while avoiding monochromatic cycles" by Nobibon, Hurkens, Leus, and Spieksma:
 * Thomas Sachin, Star coloring, 8 consecutive edits, copyvio of "Star edge coloring of some classes of graphs" by Bezegová, Lužar, Mockovčiaková, Soták, and Škrekovski: ; Star coloring, 13 consecutive edits, copyvio of "Star coloring of graphs" by Fertin, Raspaud, and Reed:
 * Vinod kalagi, Total coloring, 7 consecutive edits (interrupted by a revert), copyvio of "Total Coloring Algorithm for Graphs" by Gupta, Geetha, and Somasundaram:
 * POONAM PRAJAPAT, Total coloring, 1 edit, copyvio of "Total colouring regular bipartite graphs is NP-hard" by McDiarmid and Sanchez-Arroyo: ; Total coloring, 10 edits, interrupted by bot removal of a copyvio image, copyvio of "Total colorings of planar graphs with small maximum degree" by Wang, Wu, and Tian:
 * RAMESHVENKATCHRIST, L(h, k)-coloring, only one edit, copyvio of "The L(h, k)-labelling problem: A survey and annotated bibliography" by Calamoneri:

On my talk page it has been suggested that these might possibly be the result of a class assignment to edit Wikipedia rather than vandalistic sockpuppetry (although I find it difficult to tell the difference). Checkuser is requested because it might help sort out that issue and also because, with the pattern of individual usernames concentrating on edits to a single article, I can't tell whether I have found all of the affected articles.

 * PS this comment posted to my talk after I filed this makes it look more likely that this is a class project led by, who is apparently teaching his students to be good little plagiarists. —David Eppstein (talk) 04:35, 9 September 2015 (UTC)

 * - This is either one person or (more probably) a group of students editing from the same school. CheckUser can't help here because it will show they have the same IP either way. Their behavior is certainly disruptive, but I won't call it socking.  Vanjagenije   (talk)  19:47, 11 September 2015 (UTC)
 * I believe that we may close this now. I doubt that the instructor is encouraging plagiarism.
