The evolutionary maintenance of Lévy flight foraging. [PDF]
PLoS Computational Biology, 2022 Lévy flight is a type of random walk that characterizes the behaviour of many natural phenomena studied across a multiplicity of academic disciplines; within biology specifically, the behaviour of fish, birds, insects, mollusks, bacteria, plants, slime ...

Clustering Performance Analysis Using Chaotic and Lévy Flight-Enhanced Black-Winged Kite Algorithms [PDF]
BiomimeticsClustering is a fundamental unsupervised learning technique used to uncover hidden patterns in unlabeled data. Although metaheuristic algorithms have demonstrated effectiveness in clustering, many suffer from premature convergence and limited population ...

A Novel Ant Colony Optimization Algorithm With Levy Flight
IEEE Access, 2020 Ant Colony Optimization (ACO) is a widely applied meta-heuristic algorithm. Little researches focused on the candidate selection mechanism, which was developed based on the simple uniform distribution.

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

Calibration of camera internal parameters based on grey wolf optimization improved by levy flight and mutation [PDF]
Scientific Reports, 2022 Traditional calibration technology has been widely used in measurement and monitoring; however, there are limitations of poor calibration accuracy, which can not meet the accuracy requirements in some scenarios.

Application of Levy flight-based harmony search algorithm for the flexible job shop scheduling [PDF]
Scientific ReportsThe Flexible Job Shop Scheduling Problem (FJSP) is an extension of the classical job shop scheduling problem, which is characterized by the fact that each process can be processed on multiple candidate machines, and needs to solve the two subproblems of ...

Modified Dhole-inspired optimization for maximum power extraction in photovoltaic systems under partial shading [PDF]
Scientific ReportsIn photovoltaic systems, PSC occur when PV panels are exposed to nonuniform solar irradiance levels. Extracting the maximum power from PV systems operating under PSC represents a complex and challenging task for MPPT algorithms.

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 ...

Survey of Lévy Flight-Based Metaheuristics for Optimization
Mathematics, 2022 Lévy flight is a random walk mechanism which can make large jumps at local locations with a high probability. The probability density distribution of Lévy flight was characterized by sharp peaks, asymmetry, and trailing.
