非线性边界上随机游动无穷极大值的精确采样

Exact Sampling of the Infinite Horizon Maximum of a Random Walk Over a Non-linear Boundary

Jose Blanchet, Jing Dong, Zhipeng Liu

摘要:

我们提出的第一个算法,样本$\max_{n\geq0}\{S_{n}-n^α\},$,其中$S_n$是一个平均零随机游动,和$n^α$与$α\in(1/2,1)$定义了一个非线性边界。我们表明,我们的算法有有限的预期运行时间。我们还应用该算法构造了服务时间分布具有无穷均值的$GI/GI/\infty$队列稳态离开过程的第一精确模拟方法。

英文摘要:

We present the first algorithm that samples $\max_{n\geq0}\{S_{n}-n^α\},$ where $S_n$ is a mean zero random walk, and $n^α$ with $α\in(1/2,1)$ defines a nonliner boundary. We show that our algorithm has finite expected running time. We also apply the algorithm to construct the first exact simulation method for the steady-state departure process of a $GI/GI/\infty$ queue where the service time distribution has infinite mean.
