I would like a set of references (i.e., articles and books) for the application of the harmony search algorithm to solve discrete optimization problems such as PSP, VRP, and so on!
There is one issue with HS and that is that it has allegations of plagiarism which have been backed up by other researchers. I don't know if you are interested in using the algorithm but if that is the case I would not recommend it. I share with you some references that talk about the subject, of course they mention other works that have used HS. I hope you find it useful.
