Differential evolution utilizing a handful top superior individuals with bionic bi-population structure for the enhancement of optimization performance

ABSTRACT

In this paper, we propose a new DE variant incorporating a new mutation strategy and a bionic bi-population structure to enhance the overall performance of the canonical DE algorithm. As it is known to all that the guidance of a handful top superior elites is usually better than the guidance of only one elite in many cases, therefore, a handful top superior individuals are employed in the newly proposed mutation strategy for individual evolution. Moreover, hybridization of two populations of a certain species can improve the adaptation to the environment, and business and information exchanges between tribes can help their economical and technological development, so a bionic bi-population structure is also employed in the new DE variant for information exchanges. Both of the two aspects make the new algorithm achieve an overall better performance, and experiment results show that a handful top superior individuals with bionic bi-population structure has better performances on optimization accuracy, convergence speed and success rate under these tested benchmark functions especially those other algorithms may be trapped into local optima.

浅析现代时尚穿着中的仿生设计表现

在服装设计领域,仿生设计一直是设计师经常采用的一种设计手段,为服装的造型和色彩添加了某种情趣和主观意念的内容,设计出能够满足人类生理和心理需求的服饰,体现了人类更深层次对美的追求。仿生设计从侧面拉近了人与人、人与自然之间的距离,使我们与自然更加贴近,回归自然。
