解大规模无约束优化的自适应过滤信赖域法
Adaptive filter trust region method for large scale unconstrained optimization
摘要
Abstract
An adaptive filter trust region method for large scale unconstrained optimization is proposed.This new algorithm uses the function and its gradients to determine a scale matrix as an approximation of its Hessian matrix in the subproblem. The adaptive technique and filter technique are introduced to improve the behavior of the method.The new algorithm is shown to be globally convergent and numerical experiments indicate that it is very effective for large scale unconstrained minimization problems.关键词
