The paper considers an online estimator for the Lipschitz-smoothness parameter $L$, introduced as part of the NAG-free method for Lipschitz-smooth, strongly convex optimization pro…

Let $x,y\in\mathbb{R}^d$, $f_x,f_y\in\mathbb{R}$, $g_x,g_y\in\mathbb{R}^d$, $L>0$, and $N>0$ be given, with the quantities $B_N(x,f_x,g_x,y,g_y)$ and $U_N(x,f_x,g_x,y,g_y)$ as defi…
