An Extended Gradient Method for Smooth and Strongly Convex Functions
Mathematics, 2023 In this work, we introduce an extended gradient method that employs the gradients of the preceding two iterates to construct the search direction for the purpose of solving the centralized and decentralized smooth and strongly convex functions ...

Mathematics, 2022 Based on a successive convex programming method, an alternating iteration algorithm is proposed for solving a parameter-dependent distributionally robust optimization. Under the Slater-type condition, the convergence analysis of the algorithm is obtained.

Convergence analysis for elliptic quasivariational inequalities
Zeitschrift für angewandte Mathematik und Physik, 2023 Abstract We deal with a class of elliptic quasivariational inequalities with constraints in a reflexive Banach space. We use arguments of monotonicity, convexity and compactness in order to prove a convergence criterion for such inequalities.This criterion allows us to consider a new well-posedness concept in the study of the corresponding ...

Identifying the Unknown Source in Linear Parabolic Equation by a Convoluting Equation Method
Mathematics, 2022 This article is devoted to identifying a space-dependent source term in linear parabolic equations. Such a problem is ill posed, i.e., a small perturbation in the input data may cause a dramatically large error in the solution (if it exists).

Non-ergodic Convergence Analysis of Heavy-Ball Algorithms
, 2018 In this paper, we revisit the convergence of the Heavy-ball method, and present improved convergence complexity results in the convex setting. We provide the first non-ergodic O(1/k) rate result of the Heavy-ball algorithm with constant step size for ...

The Classical Approach to Convergence Analysis [PDF]
The Economic Journal, 1996 The concepts of sigma-convergence, absolute beta-convergence and conditional beta-convergence are discussed in this paper. The concepts are applied to a variety of data sets that include a large cross-section of 110 countries, the subsample of OECD countries, the states within the United States, the prefectures of Japan, and regions within several ...
