基于径向基函数的DIRECT全局优化方法
DIRECT global optimization method using radial basis functions
摘要
Abstract
As more evaluations of objective functions and slow convergence rate exist in DIRECT,thus a modified DIRECT method based on radial basis functions was proposed.The optimum area containing the global or local optimum was identified through analyzing the information of sampling points.The convergence rate of DIRECT method was increased through constructing the radial basis functions on the sampling points which collected from optimum area and searching global optimum on the metamodel.Finally,the method was applied to some numerical examples and a pressure vessel design.The results demonstrate the efficiency and engineering practicability of the presented method.关键词
