Block algorithms with augmented Rayleigh-Ritz projections for large-scale eigenpair computation
Zaiwen Wen, Yin Zhang
Most iterative algorithms for eigenpair computation consist of two main steps: a subspace update (SU) step that generates bases for approximate eigenspaces, followed by a Rayleigh-…

A Regularized Newton Method for Computing Ground States of Bose-Einstein condensates
Xinming Wu, Zaiwen Wen, Weizhu Bao
In this paper, we propose a regularized Newton method for computing ground states of Bose-Einstein condensates (BECs), which can be formulated as an energy minimization problem wit…

A Composite Risk Measure Framework for Decision Making under Uncertainty
Pengyu Qian, Zizhuo Wang, Zaiwen Wen
In this paper, we present a unified framework for decision making under uncertainty. Our framework is based on the composite of two risk measures, where the inner risk measure acco…
