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.

Physical Review E, 2016 Among Markovian processes, the hallmark of Lévy flights is superdiffusion, or faster-than-Brownian dynamics. Here we show that Lévy laws, as well as Gaussian distributions, can also be the limit distributions of processes with long-range memory that exhibit very slow diffusion, logarithmic in time.

Levy Flights Over Quantum Paths [PDF]
Volume 1: 20th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2005 An impact of integration over the paths of the Le´vy flights on the quantum mechanical kernel has been studied. Analytical expression for a free particle kernel has been obtained in terms of the Fox H-function. A new equation for the kernel of a partical in the box has been found.

Cuckoo Search Algorithm: Review and its Application
Tikrit 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 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
International 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 ...

On Optimal Tempered Lévy Flight Foraging
Frontiers 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.

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.
