WebJan 7, 2024 · At the same time, Lévy flights can maximize the efficiency of resource search in uncertain environments, and many optimization algorithms using Lévy flights also show excellent performance. Lévy flights is characterized by frequent short-range local searches, but occasionally a longer jump occurs and the direction of motion changes dramatically. A Lévy flight 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 of dimension greater than one, the steps made are in isotropic random directions. Later researchers have extended the use of the term "Lévy flight" to also … See more Lévy flights are, by construction, Markov processes. For general distributions of the step-size, satisfying the power-like condition, the distance from the origin of the random walk tends, after a large number of steps, to a See more 1. ^ Chechkin, Alexei V.; Metzler, Ralf; Klafter, Joseph; Gonchar, Vsevolod Yu.
