A Lévy Flight Based BAT Optimization Algorithm for Block-based Image Compression
Tehnički Glasnik, 2022 Many metaheuristics have been adopted to solve the codebook generation problem in image processing. In this paper, the Bat algorithm is combined by the Lévy flight distribution to find out the global optimum codebook.

An Improved Ant Colony Algorithm for Continuous Optimization Based on Levy Flight
Chemical Engineering Transactions, 2016 Ant colony optimization (ACO) is proposed on the study of the foraging behavior of ants on the basis of the proposed and widely used in the optimization. However, it has some shortcoming such as longer time, hardly implement and local optimal etc.

Clustering Using Levy Flight Cuckoo Search [PDF]
, 2012 In this paper, a comparative study is carried using three nature-inspired algorithms namely Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Cuckoo Search (CS) on clustering problem. Cuckoo search is used with levy flight. The heavy-tail property of levy flight is exploited here.

Scintillations and Levy Flights through the Interstellar Medium [PDF]
The Astrophysical Journal, 2003 Temporal broadening of pulsar signals results from electron density fluctuations in the interstellar medium that cause the radiation to travel along paths of different lengths. The Gaussian theory of fluctuations predicts that the pulse temporal broadening should scale with the wavelength as lambda^4, and with the dispersion measure (corresponding to ...

Time-dependent probability density function for partial resetting dynamics
New Journal of Physics, 2023 Stochastic resetting is a rapidly developing topic in the field of stochastic processes and their applications. It denotes the occasional reset of a diffusing particle to its starting point and effects, inter alia, optimal first-passage times to a target.

Application of an Enhanced Whale Optimization Algorithm on Coverage Optimization of Sensor
Biomimetics, 2023 The wireless sensor network (WSN) is an essential technology of the Internet of Things (IoT) but has the problem of low coverage due to the uneven distribution of sensor nodes.

Jumping to Conclusion? A Lévy Flight Model of Decision Making [PDF]
Tutorials in Quantitative Methods for Psychology, 2020 The diffusion model is one of the most prominent response time models in cognitive psychology. The model describes evidence accumulation as a stochastic process that runs between two boundaries until a threshold is hit, and a decision is made.

Heteroskedastic Levy Flights [PDF]
, 1999 Truncated Lévy flights are random walks in which the arbitrarily large steps of a Lévy flight are eliminated. Since this makes the variance finite, the central limit theorem applies, and as time increases the probability distribution of the increments becomes Gaussian.
