On Adapting Randomized Nystr\"{o} m Preconditioners to Accelerate Variational Image Reconstruction
Model-based iterative reconstruction plays a key role in solving inverse problems. However,
the associated minimization problems are generally large-scale, ill-posed, nonsmooth, and …

When Does Primal Interior Point Method Beat Primal-dual in Linear Optimization?
The primal-dual interior point method (IPM) is widely regarded as the most efficient IPM
variant for linear optimization. In this paper, we demonstrate that the improved stability of the …
