The Harmony Search (HS) method is an emerging metaheuristic optimization algorithm that has been used to solve numerous complex problems over the past decade. The Harmony Search algorithm (HS) was first proposed in 2001 by Z. W. Geem. The HS method is inspired by the founding principles of musical improvisation and the search for musical harmony. The combinations of perfect harmony of sounds are matched with the global extremum in the multidimensional optimization problem, while the musical improvisation process is matched with a search for the extremum.
