Wikipedia:Articles for deletion/Harmony search
There are multiple sources "actually about the topic". Sure, the original "harmony search" paper is a primary source. But the four sources that critique the use of metaphor in optimization do explicitly reference harmony search. Finally, the paper https://www.sciencedirect.com/science/article/pii/S221471601500010X|"A critical analysis of the harmony search algorithm—How not to solve sudoku" is very relevant; it deals with harmony search directly and in-depth. However, given that most of the literature is critical of harmony search, the article as is puts put |undue weight on the algorithm and under-emphasizes the controversy around it
