By Xiaolei Wang, Xiao-Zhi Gao, Kai Zenger

This short offers a close advent, dialogue and bibliographic overview of the nature1-inspired optimization set of rules known as concord seek. It makes use of a lot of simulation effects to illustrate some great benefits of concord seek and its editions and in addition their drawbacks. The authors exhibit how weaknesses should be amended by means of hybridization with different optimization equipment. The concord seek procedure with functions could be of price to researchers in computational intelligence in demonstrating the cutting-edge of study on an set of rules of present curiosity. It additionally is helping researchers and practitioners of electric and laptop engineering extra often in acquainting themselves with this system of vector-based optimization.

Based on the principle of the DC, the distances between x0 and x1 ; x2 ; . ; xn are calculated as d1, d2, …, dn. The harmony member xi that has the minimal distance to x0 is selected. If the fitness of x0 is greater than that of xi ; the latter will be replaced by the former. Otherwise, x0 is disregarded, and the iteration procedure continues. IF f ðx0 Þ [ f ðxi Þ replace xi with x0 ELSE disregard x0 END 34 5 The Hybrid Strategies of Harmony Search… Note that the above DC-like policy only applies to the solution candidates generated from the harmony memory members.

It is obvious that the DC approach used in the n-HS can prevent the harmful over-similarity among the harmony memory members so that the diversity of the HS solutions can be effectively maintained. That is to say, this modified HS method is well suited for handling the multimodal problems. Nevertheless, the n-HS has two drawbacks. Firstly, since x0 is compared with the multiparent from the harmony memory instead of only the worst harmony memory member, it may take a relatively long iteration time for the n-HS to converge.
