【Python 编程】1D 随机游走 1D Random Walk

By: Tao Steven Zheng (郑涛)

A random walk is a stochastic process that describes a path that consists of a succession of random steps on some mathematical space such as the integers. The following Python code generates three 1-dimensional random walks and plots them. Each plot starts at 0 and at each step moves up (+1) or down (−1) with equal probability.

随机游动（random walk）是一种随机过程（stochastic process），它描述了在某些数学空间（如整数）上由一系列随机步骤组成的随机游动。以下的 Python 代码生成三个一维随机游动并绘制它们。每个绘图从 0 开始，每一步以同样的概率可以向上（+1）或向下 (−1）移动。
