Research on adaptive improved harmony-simplex evolutionary algorithm
Application Research of Computers(2013)
Abstract
For the purpose of avoiding the disadvantage of harmony search algorithm,this paper proposed an adaptive improved harmony pattern search(AIHSEA) algorithm.In AIHSEA,it added a mutation strategy to enhance the robustness of HS.In order to increase the directivity of the harmony search,it implemented the simplex method timely.It adjusted its global and local searches by using adaptive parameters HMCR,PAR and BW.Finally,AIHSEA was tested by six standard benchmark functions and contrasted with HS,HIS and GHS algorithm.The test results show the favorable abilities of accuracy and escaping local minimums.
