Accelerated Additive Schwarz Methods for Convex Optimization with Adaptive Restart
Jongho Park
Based on an observation that additive Schwarz methods for general convex optimization can be interpreted as gradient methods, we propose an acceleration scheme for additive Schwarz…
Correction to: A dual iterative substructuring method with a small penalty parameter
Chang-Ock Lee, Eun-Hee Park, Jongho Park
In this corrigendum, we offer a correction to [J. Korean. Math. Soc., 54 (2017), pp. 461--477]. We construct a counterexample for the strengthened Cauchy--Schwarz inequality used i…
A variational framework for the strain-smoothed element method
Chaemin Lee, Jongho Park
This paper is devoted to a rigorous mathematical foundation for the convergence properties of the strain-smoothed element (SSE) method. The SSE method has demonstrated improved con…
An Overlapping Domain Decomposition Framework without Dual Formulation for Variational Imaging Problems
Jongho Park
In this paper, we propose a novel overlapping domain decomposition method that can be applied to various problems in variational imaging such as total variation minimization. Most…
