Dynamic Levy Flight Chimp Optimization
Knowledge-Based Systems, 2022Abstract Background: The Chimp Optimization Algorithm (ChOA) is a hunting-based model and can be utilized as a set of optimization rules to tackle optimization problems. Due to agents’ insufficient diversity in some complex problems, this algorithm is sometimes exposed to local optima stagnation.

WSAR with Levy Flight for Constrained Optimization
2022The Levy distribution, which represents a form of random walk (Levy flight) consisting of a series of consecutive random steps, has recently been demonstrated to improve the performance of metaheuristic algorithms. Through consecutive random steps, Levy flight is particularly beneficial for undertaking massive "jump" operations that allow the search to

Clustering using Cuckoo search levy flight
2016 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2016Clustering of Web document has become a vital task, due to the tremendous amount of information that is available on web today. The task of finding suitable information with less time has become a big challenge in information retrieval. So, it's very much necessary to adopt a method that can be used organize the information well.

A LEVY FLIGHT–RANDOM WALK MODEL FOR BIOTURBATION
Environmental Toxicology and Chemistry, 2002Abstract Levy flights are employed in a lattice model of contaminant migration by bioturbation, the reworking of sediment by benthic organisms. The model couples burrowing, foraging, and conveyor-belt feeding with molecular diffusion. The model correctly predicts a square-root dependence on bioturbation rates over a wide range of biomass

The Improved Equilibrium Optimization Algorithm with Levy Flight
2020 5th International Conference on Computer and Communication Systems (ICCCS), 2020It is still remaining the enthusiasm for new algorithms to solve the functions formulated by scientists describing the real world. In this paper, we improve the newly raised equilibrium optimization algorithm called here with Levy flight. Three traditional ways are discussed and the Levy flight to the best candidate in the equilibrium pool for each ...

Feature selection via competitive levy flights
2016 International Joint Conference on Neural Networks (IJCNN), 2016Evolutionary meta-heuristics are designed for optimization using population with selection and mutation operators. Novelty of our approach is based on competition of various operators from mutation portfolio. Resulting meta-heuristic is successfully tested on the feature selection task: searching for a sparse sub-model having the best possible value by

Levy flights: Variations on a theme
Physica D: Nonlinear Phenomena, 1989Abstract Levy's original ideas on limit distributions for sums of identically distributed random variables with infinite second moments are applied to a variety of topics including generating nondifferentiable lacunary series, the Riemann hypothesis, and turbulent diffusion.

Are human scanpaths Levy flights?
9th International Conference on Artificial Neural Networks: ICANN '99, 1999Introduces a phenomenological model for the generation of human scanpaths. Scanpaths, the succession of rapid eye-movements (saccades), are treated as realizations of a stochastic process in a random quenched saliency field with prespecified covariance structure.

A random walk is a stochastic process in which particles or waves travel along random trajectories. The first application of a random walk was in the description of particle motion in a fluid (brownian motion); now it is a central concept in statistical physics, describing transport phenomena such as heat, sound and light diffusion.
