Exit problem for Ornstein-Uhlenbeck processes: a random walk approach
2019-06-04 · via math.PR updates on arXiv.org

In order to approximate the exit time of a one-dimensional diffusion process, we propose an algorithm based on a random walk. Such an algorithm so-called Walk on Moving Spheres was already introduced in the Brownian context. The aim is therefore to generalize this numerical approach to the Ornstein-Uhlenbeck process and to describe the efficiency of the method.
