2D FE Quad Mesh Smoothing via Angle-Based Optimizationlysis; their improvement is important. The algorithm improves mesh quality by adjusting the position of the mesh’s internal nodes based on optimization of a torsion spring system using a Gauss-Newton-based approach. The approach obtains a reasonably optimal location of each internal node by optimizi结构 发表于 2025-3-26 03:20:50
Numerical Experiments on the Solution of the Inverse Additive Singular Value Problemorithms are analyzed and evaluated with respect to different points of view: memory requirements, convergence, accuracy and execution time, in order to observe their behaviour with different problem sizes and to identify those capable to solve the problem efficiently.LARK 发表于 2025-3-26 05:37:25

Adaptive Model Trust Region Methods for Generalized Eigenvalue Problems. In this paper, two methods that compute extreme eigenpairs of positive-definite matrix pencils are combined into a hybrid scheme that inherits the advantages of both constituents. The hybrid algorithm is developed and analyzed in the framework of model-based methods for trace minimization.Substance 发表于 2025-3-26 16:37:08

Bifurcation Analysis of Large Equilibrium Systems in ,.). In the case when .(.) is the Jacobian matrix for a system that comes from a spatial discretization of a partial differential equation, it will typically be large and sparse. . is a user-friendly . package for the study of dynamical systems and their bifurcations. We incorporate the CIS algorithm
