Environmental constraints on human memory
… foraging displays a fractal pattern known as Lévy flights. Lévy flights or Lévy distributions are positively skewed; heavy-tailed distributions that contain many more extremely large distances than would be expected from a Gaussian distribution and have a slope of (1 < ≤ 3). Although, any …

Standard and Anomalous Wave Transport Inside Random Media
… wave transport inside random systems with Lévy disorder, in which waves perform Lévy flights. We find the average logarithm of transmission scales as a power law with system length, ⟨ln <em>T</em>⟩∝-<em>L</em>^<em>α</em>, and the mean transmission scales as a power law for large <em>L</em>, …

An improved firefly algorithm for optimal microgrid operation with renewable energy
… (FA) technique using characteristic approach of Lévy flights to solve the optimal microgrid operation. The IFA has been used for optimizing the cost of power generation in microgrid system where daily power balance constraints and generation limits are considered. The microgrid system for this …

An entropic approach to the analysis of time series.
… time series is characterized, for example, by Lévy statistics, H ¹ d and the variance methods cannot be used to detect the true scaling. Lévy walk yields the relation d=1/(3-2H). In the case of Lévy flights, the variance diverges and the exponent H cannot be determined, whereas the scaling d …
