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...

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...

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

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...

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...

a random walk, the self-avoiding walk. The simplest possible polymer model is presented by the ideal chain, corresponding to a simple random walk. Experimental...

scatter the light path further, hence the name "random walk". Isotropic scattering is simulated by picking random directions evenly along a sphere. Anisotropic...

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...

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 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...

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

hand) of the game is not independent of the past states. Consider a random walk on the number line where, at each step, the position (call it x) may...

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...

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...

In network science, a biased random walk on a graph is a time path process in which an evolving variable jumps from its current state to one of various...

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

The persistent random walk is a modification of the random walk model. A population of particles are distributed on a line, with constant speed c 0 {\displaystyle...

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...

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

swimming in a uniform environment will form a random walk with relatively straight swims interrupted by random tumbles that reorient the bacterium. Bacteria...

higher dimensions, the SAW is believed to behave much like the ordinary random walk. SAWs and SAPs play a central role in the modeling of the topological...
