Lévy flights and earthquakes [PDF]
Geophysical Research Letters, 2000 Lévy flights representation is proposed to describe earthquake characteristics like the distribution of waiting times and position of hypocenters in a seismic region. Over 7500 microearthquakes and earthquakes from 1985 to 1994 were analyzed to test that

Computer Simulation Study of the Levy Flight Process [PDF]
Physica A: Statistical Mechanics and its Applications, 2010 Random walk simulation of the Levy flight shows a linear relation between the mean square displacement and time. We have analyzed different aspects of this linearity.

Mean number of visits to sites in Levy flights [PDF]
Physical Review E, 2006 Formulas are derived to compute the mean number of times a site has been visited during symmetric Levy flights. Unrestricted Levy flights are considered first, for lattices of any dimension: conditions for the existence of finite asymptotic maps of the ...

Mutations as Levy flights [PDF]
Scientific Reports, 2021 AbstractData from a long time evolution experiment with Escherichia Coli and from a large study on copy number variations in subjects with European ancestry are analyzed in order to argue that mutations can be described as Levy flights in the mutation space. These Levy flights have at least two components: random single-base substitutions and large DNA

First passage and first hitting times of Lévy flights and Lévy walks [PDF]
New Journal of Physics, 2019 For both Lévy flight and Lévy walk search processes we analyse the full distribution of first-passage and first-hitting (or first-arrival) times. These are, respectively, the times when the particle moves across a point at some given distance from its ...

Swarm Crawler Robots Using Lévy Flight for Targets Exploration in Large Environments
Robotics, 2022 This study tackles the task of swarm robotics, where robots explore the environment to detect targets. When a robot detects a target, the robot must be connected with a base station via intermediate relay robots for wireless communication.

LFGCN: Levitating over Graphs with Levy Flights [PDF]
2020 IEEE International Conference on Data Mining (ICDM), 2020 Due to high utility in many applications, from social networks to blockchain to power grids, deep learning on non-Euclidean objects such as graphs and manifolds, coined Geometric Deep Learning (GDL), continues to gain an ever increasing interest. We propose a new Lévy Flights Graph Convolutional Networks (LFGCN) method for semi-supervised learning ...

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...
