Deletion of Natural Constraint Language

Comment: Both this article and the companion article Mixed Set Programming (see Wikipedia:Articles for deletion/Mixed Set Programming) seem to be referenced entirely to the work of one "J. Zhou".  They seem to be on highly technical subjects, but the style seems generally informative; they don't read like typical  text.  If they're meant to promote something, I'm so far outside the target market that I didn't notice. No opinion yet on whether this should be kept or deleted. If one is kept, I suspect the other could be merged into it

Comment: Given the recent appearance of some {{tl|spa}} tags, I think it's worth recalling this text from : "However a user who edits appropriately and makes good points that align with Wikipedia's communal norms, policies and guidelines should have their comment given full weight regardless of any tag."  In particular, the original nomination already mentioned that the creator of the page is an SPA; adding a tag to SophiePaul's name at this late stage of the discussion seems redundant.  I hope that comments will be evaluated according to their merit
