CHAPTER 7 Harmony search algorithm N.P. Theodossiou & I.P. Kougias Division of Hydraulics and Environmental Engineering, Department of Civil Engineering, Aristotle University of Thessaloniki, Greece. Abstract During the past few years, a new method has been added to those optimization techniques inspired by natural phenomena like genetic algorithms. The music-inspired harmony based optimization algorithm, commonly referred to as Harmony Search Algorithm (HSA), is a novel, powerful optimization technique based on the observation of music creation and its quest of the perfect state of harmony. In this chapter, the concept and the basic characteristics of the harmony search algorithm are comprehensively presented. Since the method is still in full development, a number of variations aiming to improve its effi ciency have appeared. Their main differences are also outlined in this chapter along with a benchmark evaluation of their effectiveness. Finally, an application on a classic multireservoir system management problem is presented, in order to demonstrate the effi ciency of the Harmony Search Algorithm. Keywords: optimization techniques, Harmony Search Algorithm, music-inspired harmony based optimization algorithm, Rosenbrock function, Griewangk function, multi-reservoir management.
