HNAG${}^{++}$: An Accelerated Gradient Method with a Refined Asymptotic Rate for Strongly Convex Optimization

Long Chen, Zeyi Xu

Two accelerated first-order methods, HNAG${}^{+}$ and HNAG${}^{++}$, are introduced for smooth strongly convex optimization. They are derived from the Hessian-driven Nesterov Accelerated…
