摘要:

该文首先基于 Broyden-Fletcher-Goldfarb-Shanno 更新, 给出一类改进的三项搜索方向. 结合惯性策略和超平面投影技术, 提出一个惯性的三项共轭梯度投影法用于求解无约束非线性单调方程组. 所提惯性算法具有如下特征: (i) 其搜索方向独立于任何线搜索, 有充分下降性和信赖域性质; (ii) 惯性技术采用三步迭代信息以产生惯性迭代点; (iii) 底层映射无需满足 Lipschitz 连续性, 亦可获得算法的全局收敛性结果. 通过初步数值试验结果验证了算法的有效性.

关键词: 非线性单调方程组, 三项共轭梯度法, 惯性策略, BFGS 更新, 全局收敛性

Abstract:

Based on the BFGS update, in this paper, we present a class of improved three-term search directions. Then, by combining the inertial strategy and hyperplane projection approach, an inertial three-term conjugate gradient projection method is proposed for solving unconstrained nonlinear monotone equations. The proposed inertial algorithm exhibits the following features: (i) its search direction always possesses sufficient descent and trust region properties, independent of any line search; (ii) the inertial strategy generates iterative points by utilizing information from three iterations; (iii) the method achieves global convergence results without assuming the underlying mapping to satisfy Lipschitz continuity. Preliminary numerical experiments verify the effectiveness of the proposed method.

Key words: nonlinear monotone equations, three-term conjugate gradient method, inertial strategy, BFGS Update, global convergence
