Interactive Levy Flight in Interest Space

open access: yesCoRR, 2017
Compared to the well-studied topic of human mobility in real geographic space, very few studies focus on human mobility in virtual space, such as interests, knowledge, ideas, and so forth. However, it relates to the issues of management of public opinions, knowledge diffusion, and innovation.

Cuckoo Search Algorithm: Review and its Application

open access: yesTikrit Journal of Pure Science, 2022
Optimization techniques play a major role in real-world problems, As many cases in which decisions are made are based on random research. But choosing the optimization technology is a big challenge for the user. The cuckoo search algorithm is one of the

Lévy flights and Lévy-Schrödinger semigroups [PDF]

open access: yesOpen Physics, 2010
Abstract We analyze two different confining mechanisms for Lévy flights in the presence of external potentials. One of them is due to a conservative force in the corresponding Langevin equation. Another is implemented by Lévy-Schrödinger semigroups which induce so-called topological Lévy processes (Lévy flights with locally modified jump

Levy Foraging in a Dynamic Environment – Extending the Levy Search

open access: yesInternational Journal of Advanced Robotic Systems, 2015
A common task for robots is the patrolling of an unknown area with inadequate information about target locations. Under these circumstances it has been suggested that animal foraging could provide an optimal or at least sub-optimal search methodology ...

Lévy flights in a box [PDF]

open access: yesChaos, Solitons & Fractals, 2015
It is shown that a quantum Lévy process in a box leads to a problem involving topological constraints in space, and its treatment in the framework of the path integral formalism with the Lévy measure is suggested. The eigenvalue problem for the infinite potential well is properly defined and solved.

Clustering Using Levy Flight Cuckoo Search [PDF]

open access: yes, 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.

On Optimal Tempered Lévy Flight Foraging

open access: yesFrontiers in Physics, 2018
Optimal random foraging strategy has gained increasing concentrations. It is shown that Lévy flight is more efficient compared with the Brownian motion when the targets are sparse.

A Lévy Flight Based BAT Optimization Algorithm for Block-based Image Compression

open access: yesTehnički 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

open access: yesChemical 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.
