基于物理知识驱动的敏感性分析及分区代理模型优化方法
Sensitivity analysis and optimization method of partition surrogate model based on physical knowledge driven
摘要
Abstract
The problem of"dimensionality disaster"of design variable is a key technical problem that restricts the ap-plication of current agent-based optimization algorithms.In order to solve the problem of declining accuracy and poor optimization effect of surrogate model caused by dimensionality disaster problem,a sensitivity analysis parti-tion surrogate model optimization method based on physical knowledge driven is improved.The sensitivity of differ-ent partition design variables to the objective function is studied.On the basis of the sequential partition optimiza-tion,the sensitivity is taken as the order of the partition surrogate model optimization.The results show that the method can solute the high-dimensional design space into a series of low-dimensional subspaces,improve the pre-diction accuracy of surrogate model,realize the efficiency configuration,so as to realize the global search.In com-parison with traditional surrogate optimization method,the time spent on establishing the surrogate model is much lower,and the ability of surrogate optimization method to solve the high-dimensional aerodynamics design problem.关键词
