AN INTRODUCTION TO THE HARMONY SEARCH ALGORITHM
Gordon D. Ingram, Tonghua Zhang · Advances in process systems engineering · 2010
The Harmony Search (HS) draws its inspiration not from a biological or physical process like most other meta-heuristic optimization techniques, but from an artistic one---the improvisation process of musicians. The primary aim of this chapter is to introduce the Chemical Engineering community to the HS method and its current applications. The algorithm has been reported to be a competitive alternative to other SGO techniques in related engineering disciplines, but has received little attention for process applications. Being a relatively young algorithm, there are good opportunities for exploring variations on the basic method to tailor it to Chemical Engineering problems. With this in mind, the secondary aim of the chapter is to provide a convenient summary of the many modifications to the basic algorithm. This is the first time that a comprehensive summary of HS modifications has been presented in the literature.
