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 visits over the lattice are analysed and a connection is made with the transience of the flight.

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.

Scintillations and Levy Flights through the Interstellar Medium [PDF]
The Astrophysical Journal, 2003 Temporal broadening of pulsar signals results from electron density fluctuations in the interstellar medium that cause the radiation to travel along paths of different lengths. The Gaussian theory of fluctuations predicts that the pulse temporal broadening should scale with the wavelength as lambda^4, and with the dispersion measure (corresponding to ...

Time-dependent probability density function for partial resetting dynamics
New Journal of Physics, 2023 Stochastic resetting is a rapidly developing topic in the field of stochastic processes and their applications. It denotes the occasional reset of a diffusing particle to its starting point and effects, inter alia, optimal first-passage times to a target.

Heteroskedastic Levy Flights [PDF]
, 1999 Truncated Lévy flights are random walks in which the arbitrarily large steps of a Lévy flight are eliminated. Since this makes the variance finite, the central limit theorem applies, and as time increases the probability distribution of the increments becomes Gaussian.

The Weierstrassian movement patterns of snails [PDF]
Royal Society Open Science, 2017 Weierstrassian Lévy walks are the archetypical form of random walk that do not satisfy the central limit theorem and are instead characterized by scale invariance.

Application of an Enhanced Whale Optimization Algorithm on Coverage Optimization of Sensor
Biomimetics, 2023 The wireless sensor network (WSN) is an essential technology of the Internet of Things (IoT) but has the problem of low coverage due to the uneven distribution of sensor nodes.
