Progressive Bound Strengthening via Doubly Nonnegative Cutting Planes for Nonconvex Quadratic Programs

Zheng Qu, Defeng Sun, Jintao Xu

We introduce a cutting-plane framework for nonconvex quadratic programs (QPs) that progressively tightens convex relaxations. Our approach leverages the doubly nonnegative (DNN) re…

Drop-Muon: Update Less, Converge Faster

Kaja Gruntkowska, Yassine Maziane, Zheng Qu +1

Conventional wisdom in deep learning optimization dictates updating all layers at every step-a principle followed by all recent state-of-the-art optimizers such as Muon. In this wo…

Entropic Regularization of the Nested Distance

Zheng Qu, Benoît Tran

In 2012, Pflug and Pichler proved, under regularity assumptions, that the value function in Multistage Stochastic Programming (MSP) is Lipschitz continuous w.r.t. the Nested Distan…

An adaptive proximal point algorithm framework and application to large-scale optimization

Meng Lu, Zheng Qu

We investigate the proximal point algorithm (PPA) and its inexact extensions under an error bound condition, which guarantees a global linear convergence if the proximal regulariza…

An inexact proximal augmented Lagrangian framework with arbitrary linearly convergent inner solver for composite convex optimization

Fei Li, Zheng Qu

We propose an inexact proximal augmented Lagrangian framework with explicit inner problem termination rule for composite convex optimization problems. We consider arbitrary linearl…

Solving Ergodic Markov Decision Processes and Perfect Information Zero-sum Stochastic Games by Variance Reduced Deflated Value Iteration

Marianne Akian, Stéphane Gaubert, Zheng Qu +1

Recently, Sidford, Wang, Wu and Ye (2018) developed an algorithm combining variance reduction techniques with value iteration to solve discounted Markov decision processes. This al…
