摘要
用极大似然估计法和交替方向法估计Kriging模型参数,提出一种基于有效集共轭梯度法的Kriging模型参数优化算法,并在此基础上改进了高效全局优化算法.结果表明,利用改进的全局优化算法可解决高效全局优化算法的过早收敛问题.
Based on the maximum likelihood estimation method and the alternating direction method to estimate the parameters of Kriging model,a Kriging model parameter optimization algorithm based on active set conjugate gradient method was proposed on the basis of which the global optimization algorithm was improved.Finally,the problem of premature convergence has been solved by means of the improved global optimization algorithm.
