mathematics, a random walk, sometimes known as a drunkard's walk, is a stochastic process that describes a path that consists of a succession of random steps on...

The random walk hypothesis is a financial theory stating that stock market prices evolve according to a random walk (so price changes are random) and thus...

Quantum walks are quantum analogs of classical random walks. In contrast to the classical random walk, where the walker occupies definite states and the...

A Random Walk Down Wall Street, written by Burton Gordon Malkiel, a Princeton University economist, is a book on the subject of stock markets which popularized...

is a random walk in which the step-lengths have a stable distribution, a probability distribution that is heavy-tailed. When defined as a walk in a space...

signal noise produced by Brownian motion, hence its alternative name of random walk noise. The term "Brown noise" does not come from the color, but after...

Random Walk is a 1988 novel by Lawrence Block. It was first published by Tor Books. One day, Guthrie Wagner hears a voice telling him to abandon his life...

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...

In mathematics, loop-erased random walk is a model for a random simple path with important applications in combinatorics, physics and quantum field theory...

The random walk model of consumption was introduced by economist Robert Hall. This model uses the Euler numerical method to model consumption. He created...

random walk, or other discrete-time stochastic processes with stationary independent increments. This is known as Donsker's theorem. Like the random walk...

a simple random walk in two dimensions, but they start from different points. The simplest way to couple them is simply to force them to walk together...

instead of following a strict random walk, stock price variations executed a Lévy flight. A Lévy flight is a random walk that is occasionally disrupted...

stochastic processes which converge (in the limit) to Brownian motion (see random walk and Donsker's theorem). The Roman philosopher-poet Lucretius' scientific...

either of indegree and outdegree can be used for normalization: The left (random-walk) normalized Laplacian matrix is defined as: L rw := D + L = I − D + A...

Random walk closeness centrality is a measure of centrality in a network, which describes the average speed with which randomly walking processes reach...

the random walk hypothesis. The random walk index (RWI) is a technical indicator that attempts to determine if a stock's price movement is random in nature...

A distinguishing feature of diffusion is that it depends on particle random walk, and results in mixing or mass transport without requiring directed bulk...
