On harmony search based optimal design of water distribution network

This paper describes a new meta-heuristic algorithm,called the harmony search (HS),which was conceptualized using the musical process of searching for a perfect state of har- mony.The HS algorithm does not require initial values and uses a random search instead of a gradi- ent search,so derivative information is unnecessary.This study focused on pipe diameter optimiza- tion while minimizing design cost,then compared the results of HS with genetic algorithm.The re- suits are very promising and demonstrate the usefulness of harmony search algorithms in solving this kind of optimization problem.
