Harmony Search Algorithm Based on Cloud Theory

Abstract:

The parameter bw is a distance bandwidth between 0 and 1 in harmony search algorithm, which helps the algorithm in finding globally and locally improved solution. In this paper, a new harmony search algorithm is proposed in order to improve the convergence speed and the global search algorithm of the harmony search algorithm. The parameter bw is adjusted based on cloud theory in this new algorithm. The new algorithm is tested on some benchmark functions and the results are compared with the result of the traditional harmony search. Experimental results indicate that the new harmony search algorithm has a good performance in the global search ability and convergent speed.
