An Adaptive Trust-region Method for Solving Generalized Eigenvalues of Tensors
摘要
Abstract
Tensor eigenvalue problem is an important branch of matrix theory and has a wide range of applications in many scientific fields.A non-monotonic adaptive trust-region method for solving the generalized eigenvalues of symmetric tensors is proposed in this paper.In order to get the maximum generalized eigenvalue of the symmetric tensor,the algorithm applies the projection method in the iteration step to ensure that the iteration points are feasible.Besides,the algorithm combines the adaptive technique to automatically update the radius of the trust region.Meanwhile,the global convergence of the algorithm is proved and the optimal solution satisfies the second-order necessary condition.Numerical experiments show that the algorithm is feasible and effective.关键词
