Adaptivity, Anchoring, and the Exact Oracle Complexity of Stochastic Fixed-Point Iterations

Yekini Shehu

We study stochastic fixed-point iterations $x_{n + 1} = θ_{n} x_{0} + (1 - θ_{n}) T (x_{n})$ for nonexpansive and contractive operators on Hilbert spaces, with a single-point unbiased oracle…

Primal Methods for Constrained Variational Inequalities: Optimal Rates, Feasibility Trade-offs, and Lower Bounds

Yonghong Yao, Lateef O. Jolaoso, Yekini Shehu +1

Since Zhang et al. \cite{Zhang2025} introduced the first purely primal methods for monotone variational inequalities subject to convex functional constraints, the field has lacked…

The sharp step-size constant for one-call reflection splittings on monotone inclusions

Yekini Shehu

The forward-reflected-backward splitting of Malitsky and Tam converges weakly for step sizes $λ \in (0, \frac{1}{2 L})$ , where $B$ is monotone and $L$ -Lipschitz, and the question whet…

A Parameter-Free Adaptive Reflected Gradient Method for Monotone Variational Inequalities

Yekini Shehu

We analyze a one-evaluation-per-iteration method for $VI (C, B)$ with monotone $L$ -Lipschitz $B$ : $x_{k + 1} = P_{C} (x_{k} - λ B (u_{k}))$ , $u_{k} = x_{k} + θ_{k} (x_{k} - x_{k - 1}) + β_{k} (x_{k} - u_{k - 1})$ , $θ…
