On the Height of One-Dimensional Random Walk
Mathematics, 2023 Consider the one-dimensional random walk Xn: as it evolves (at each unit of time), it either increases by one with probability p or resets to 0 with probability 1−p.

Weak convergence and optimal scaling of random walk Metropolis algorithms
, 1997 This paper considers the problem of scaling the proposal distribution of a multidimensional random walk Metropolis algorithm in order to maximize the efficiency of the algorithm. The main result is a weak convergence result as the dimension of a sequence

Survey on community detection method based on random walk
Tongxin xuebao, 2023 Random walk techniques achieve high accuracy and efficiency in community detection.To summarize and analyze community detection methods based on random walk, the random walk technique was classified into personalized PageRank, heat kernel diffusion and ...

Recurrence of the plane Elephant random walk
Comptes Rendus. MathématiqueWe give a short proof of the recurrence of the two-dimensional elephant random walk in the diffusive regime. This was recently established by Qin (2023), but our proof mainly uses very rough comparison with the standard plane random walk.

Bindweeds or random walks in random environments on multiplexed trees and their asympotics [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 We report on the asymptotic behaviour of a new model of random walk, we term the bindweed model, evolving in a random environment on an infinite multiplexed tree.The term multiplexed means that the model can be viewed as a nearest neighbours random walk ...

A random walk with catastrophes
Electronic Journal of Probability, 2019 Random population dynamics with catastrophes (events pertaining to possible elimination of a large portion of the population) has a long history in the mathematical literature. In this paper we study an ergodic model for random population dynamics with linear growth and binomial catastrophes: in a catastrophe, each individual survives with some fixed ...

A random walk down Main Street
TeMA: Journal of Land Use, Mobility and Environment, 2016 US suburbs have often been characterized by their relatively low walk accessibility compared to more urban environments, and US urban environments have been char- acterized by low walk accessibility compared to cities in other countries.

Lengths and heights of random walk excursions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Consider a simple symmetric random walk on the line. The parts of the random walk between consecutive returns to the origin are called excursions. The heights and lengths of these excursions can be arranged in decreasing order.

Annales Henri Lebesgue, 2022 In this article we define and study a stochastic process on Galoisian covers of compact manifolds. The successive positions of the process are defined recursively by picking a point uniformly in the Dirichlet domain of the previous one. We prove a theorem la Kesten for such a process: the escape rate of the random walk is positive if and only if the

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
