Deletion of Imperialist competitive algorithm

Comment: I can't spot "metaphor-inspired metaheuristic cruft" among our #REASON|reasons for deletion, so I'll assume it's the subject's |notability that's in question. The above Google Scholar search, besides showing 995 citations of the original paper, reveals two book chapters with this title which constitute significant coverage in what appear to be independent reliable sources sufficient to meet :http://link.springer.com/chapter/10.1007/978-3-319-03404-1_15 http://link.springer.com/chapter/10.1007/978-3-319-05549-7_11. (If there's some close connection between the authors of these chapters and the authors of the original paper that means they're not independent sources, it's not obvious to me
