Counterexamples to Whole-Sequence Convergence of Variable-Smoothing Full-Splitting Methods
Min Tao
We study whole-sequence convergence of the smoothing-based full-splitting proximal subgradient method (S-FSPS) for structured nonconvex and nonsmooth fractional programs, introduce…

Limited-angle CT reconstruction via the L1/L2 minimization
Chao Wang, Min Tao, James Nagy +1
In this paper, we consider minimizing the L1/L2 term on the gradient for a limited-angle scanning problem in computed tomography (CT) reconstruction. We design a specific splitting…

On the Optimal Linear Convergence Rate of a Generalized Proximal Point Algorithm
Min Tao, Xiaoming Yuan
The proximal point algorithm (PPA) has been well studied in the literature. In particular, its linear convergence rate has been studied by Rockafellar in 1976 under certain conditi…
