A Multiscale Primal-Dual Interior-Point Relaxation Method for Large-Scale Optimal Transport Problems

Shengyu Sun, Rui-Jin Zhang, Ruoyu Diao +1

Large-scale optimal transport (OT) problems involve a vast number of transport variables, leading to prohibitive memory and computational costs. To address these challenges, we pro…

Polynomial iteration complexity of a path-following smoothing Newton method for symmetric cone programming

Yu-Hong Dai, Ruoyu Diao, Xin-Wei Liu +1

It has long remained open whether smoothing Newton methods (SNMs) for symmetric cone programming (SCP) admit polynomial iteration complexity. A key difficulty lies in the lack of a…
