Let $f:\mathbb{R}^d\to \mathbb{R}$ be smooth and convex with at most linear growth (you can assume Lipschitzness if it simplifies). Fix any $t>0$. It is clear that a maximizer of the following Hopf--Lax type formula exists:
$$\sup_{x\in\mathbb{R}^d}\left\{f(x) - \frac{|x|^2}{t}\right\}.$$
Fix an arbitrary maximizer $x_0$ of this formula.
Question: Does there exist a sequence $(x_\epsilon)_{\epsilon>0}$ such that
for each $\epsilon>0$, $x_\epsilon$ is a maximizer of$$\sup_{x\in\mathbb{R}^d}\left\{f(x) - \frac{|x|^2}{t+\epsilon}\right\},$$
and $x_\epsilon$ converges to $x_0$ as $\epsilon\to 0$?
