Branching random walk

Stochastic process

In probability theory, a branching random walk is a stochastic process that generalizes both the concept of a random walk and of a branching process. At every generation, a branching random walk's value is a set of elements that are located in some linear space, such as the real line. Each element of a given generation can have several descendants in the next generation. The location of any descendant is the sum of its parent's location and a random variable.
