基于单纯形的改进全局人工鱼群优化算法
Improved Global Artificial Fish Swarm Algorithm Based on Simplex Method
摘要
Abstract
In order to overcome the drawbacks of Global Artificial Fish Swarm Algorithm ( GAFSA) ,such as slow convergence and low precision optimization,a modified GAFSA ( MS GAFSA) is proposed,in which the modified simplex method is adopted to improve con-vergence precision and convergence rate. For GAFSA has a faster convergence in optimization of the early and the ability to recognize the local optimum value,a simplex is constructed based on the minimum given by GAFSA when the convergence turned to the stable point. Make the simplex move and roll by reflection,expansion and contraction. Compared the values of the simplex’ s vertexes,constructing a new simplex by the trend of function,and repeating the process till the result is accurate enough. The computational results on benchmark functions show that MS GAFSA achieves higher performance,including convergence precision and convergence rate.关键词
