A Cuckoo Search Algorithm Using Improved Beta Distributing and Its Application in the Process of EDM
Crystals, 2021 Lévy flights random walk is one of key parts in the cuckoo search (CS) algorithm to update individuals. The standard CS algorithm adopts the constant scale factor for this random walk. This paper proposed an improved beta distribution cuckoo search (IBCS)

Generalized entropies and the transformation group of superstatistics [PDF]
, 2011 Superstatistics describes statistical systems that behave like superpositions of different inverse temperatures $\beta$, so that the probability distribution is $p(\epsilon_i) \propto \int_{0}^{\infty} f(\beta) e^{-\beta \epsilon_i}d\beta$, where the ...

Stein's method of exchangeable pairs for the Beta distribution and generalizations [PDF]
, 2014 . We propose a version of Stein’s method of exchangeable pairs, which, given a suitable exchangeable pair (W,W ) of real-valued random variables, suggests the approximation of the law of W by a certain absolutely continuous distribution, which is ...

Using the beta distribution to analyse plant cover data
Journal of Ecology, 2019 Most plant species are spatially aggregated. Local demographic and ecological processes (e.g. vegetative growth and limited seed dispersal) result in a clustered spatial pattern within an environmentally homogenous area.
