Ornstein-Uhlenbeck过程的出口问题:一种随机游动方法

Exit problem for Ornstein-Uhlenbeck processes: a random walk approach

Samuel Herrmann, Nicolas Massin

摘要:

为了逼近一维扩散过程的退出时刻,我们提出了一种基于随机游动的算法。这样一个算法,即所谓的在移动球体上行走,已经在布朗背景下引入。因此,我们的目的是推广这种数值方法的Ornstein-Uhlenbeck过程,并描述该方法的效率。

英文摘要:

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.
