Biao Zhang, Huihui Yan, Junhua Duan, Liang, J.J., Hong-yan Sang, Quan-ke Pan.  2014.  An improved harmony search algorithm with dynamic control parameters for continuous optimization problems. Control and Decision Conference (2014 CCDC), The 26th Chinese. :966-971.

An improved harmony search algorithm is presented for solving continuous optimization problems in this paper. In the proposed algorithm, an elimination principle is developed for choosing from the harmony memory, so that the harmonies with better fitness will have more opportunities to be selected in generating new harmonies. Two key control parameters, pitch adjustment rate (PAR) and bandwidth distance (bw), are dynamically adjusted to favor exploration in the early stages and exploitation during the final stages of the search process with the different search spaces of the optimization problems. Numerical results of 12 benchmark problems show that the proposed algorithm performs more effectively than the existing HS variants in finding better solutions.
