Accelerated Hybrid Subgradient Extragradient Methods for Solving Bilevel Split Quasimonotone Variational Inequality Problems

Journal of Optimization, Differential Equations and Their Applications
In this paper, we introduce and study a modified inertial subgradient extragradient iterative algorithm for solving bilevel split quasimonotone variational inequality problems with a fixed point constraint of demimetric mappings in the framework of real ...

Can Omitted Carbon Abatement Explain Productivity Stagnation?

Review of Income and Wealth, Volume 71, Issue 2, May 2025.
ABSTRACT Explaining the secular stagnation of productivity growth is a widely recognized challenge to economists and policymakers. One potentially important explanation without much attention concerns the ongoing low‐carbon transition. This paper explores whether considering greenhouse gas emissions can explain productivity stagnation in OECD countries.

The Jacobian Consistency of a One-Parametric Class of Smoothing Functions for SOCCP

Abstract and Applied Analysis, 2013
Second-order cone (SOC) complementarity functions and their smoothing functions have been much studied in the solution of second-order cone complementarity problems (SOCCP).

Modified Spectral Projected Subgradient Method: Convergence Analysis and Momentum Parameter Heuristics

Bulletin of Computational Applied Mathematics, 2016
The Modified Spectral Projected Subgradient (MSPS) was proposed to solve Langrangen Dual Problems, and its convergence was shown when the momentum term was zero. The MSPS uses a momentum term in order to speed up its convergence.

A new modified deflected subgradient method

Journal of King Saud University - Science, 2018
Abstract A new deflected subgradient algorithm is presented for computing a tighter lower bound of the dual problem. These bounds may be useful in nodes evaluation in a Branch and Bound algorithm to find the optimal solution of large-scale integer linear programming problems.
