Walker process

The Walker process refers to a mathematical model used to describe random movement, often likened to the motion of a person taking steps in a random direction. In more technical contexts, it represents a type of stochastic process, where each step is determined by chance rather than a fixed path. This concept is vital in fields like physics, finance, and biology, as it helps analyze behaviors and predict outcomes in systems with inherent uncertainty, such as stock market fluctuations or the movement of particles. Essentially, it captures how randomness influences change over time.
