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 ...

Cumulant Approach of Arbitrary Truncated Levy Flight [PDF]
Physica A: Statistical Mechanics and its Applications, 2010 The problem of an arbitrary truncated Levy flight description using the method of cumulant approach has been solved. The set of cumulants of the truncated Levy distribution given the assumption of arbitrary truncation has been found.

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 ...

Cuckoo Search via Levy Flights [PDF]
, 2009 In this paper, we intend to formulate a new metaheuristic algorithm, called Cuckoo Search (CS), for solving optimization problems. This algorithm is based on the obligate brood parasitic behaviour of some cuckoo species in combination with the Levy ...

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.

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.

Intrinsic bursts facilitate learning of Lévy flight movements in recurrent neural network models [PDF]
Scientific Reports, 2022 Isolated spikes and bursts of spikes are thought to provide the two major modes of information coding by neurons. Bursts are known to be crucial for fundamental processes between neuron pairs, such as neuronal communications and synaptic plasticity ...

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 ...

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
