Single-Loop Algorithm for Composite Optimization

Published:Dec 30, 2025 08:09
1 min read
ArXiv

Analysis

This paper introduces and analyzes a single-loop algorithm for a complex optimization problem involving Lipschitz differentiable functions, prox-friendly functions, and compositions. It addresses a gap in existing algorithms by handling a more general class of functions, particularly non-Lipschitz functions. The paper provides complexity analysis and convergence guarantees, including stationary point identification, making it relevant for various applications where data fitting and structure induction are important.
Reference

“The algorithm exhibits an iteration complexity that matches the best known complexity result for obtaining an (ε₁,ε₂,0)-stationary point when h is Lipschitz.”

Stable Numerical Methods for Viscoelastic Giesekus Model

Published:Dec 28, 2025 08:10
1 min read
ArXiv

Analysis

This paper addresses the challenges of numerically solving the Giesekus model, a complex system used to model viscoelastic fluids. The authors focus on developing stable and convergent numerical methods, a significant improvement over existing methods that often suffer from accuracy and convergence issues. The paper's contribution lies in proving the convergence of the proposed method to a weak solution in two dimensions without relying on regularization, and providing an alternative proof of a recent existence result. This is important because it provides a reliable way to simulate these complex fluid behaviors.
Reference

“The main goal is to prove the (subsequence) convergence of the proposed numerical method to a large-data global weak solution in two dimensions, without relying on cut-offs or additional regularization.”
