Direct Spectral Acceleration of First-Order Methods for Saddle Point Problems with Bilinear Coupling

Meng Li, Paul Grigas

We study convex-concave saddle point problems with bilinear coupling, covering linearly constrained convex optimization and more general nonsmooth or constrained models via a proxi…

Adaptive moving mesh methods for the planar Willmore flow

Zhenghua Duan, Meng Li

In this paper, we propose adaptive moving mesh methods for the planar Willmore flow by incorporating a tangential velocity into the original geometric evolution. The tangential vel…
