Maximal dispersion of adaptive random walks

open access: yesPhysical Review Research, 2022
Maximum entropy random walks (MERWs) are maximally dispersing and play a key role in optimizing information spreading in various contexts. However, building MERWs comes at the cost of knowing beforehand the global structure of the network, a requirement ...

Some topics in random walks [PDF]

open access: yesESAIM: Proceedings and Surveys
We collect a few recent results on random walks, which are ubiquitous in probability theory. The topics covered are: persistence problems for stochastic processes, large fluctuations in multi-scale modeling for rest hematopoiesis, and fine properties of ...

Deterministic Random Walks on the Integers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We analyze the one-dimensional version of Jim Propp's $P$-machine, a simple deterministic process that simulates a random walk on $\mathbb{Z}$. The "output'' of the machine is astonishingly close to the expected behavior of a random walk, even on long ...

Generalized continuous-time random walks, subordination by hitting times, and fractional dynamics [PDF]

open access: yes, 2009
Functional limit theorems for continuous-time random walks (CTRW) are found in the general case of dependent waiting times and jump sizes that are also position dependent.

On random walks and switched random walks on homogeneous spaces

open access: yesCombinatorics, Probability and Computing, 2022
AbstractWe prove new mixing rate estimates for the random walks on homogeneous spaces determined by a probability distribution on a finite group$G$. We introduce the switched random walk determined by a finite set of probability distributions on$G$, prove that its long-term behaviour is determined by the Fourier joint spectral radius of the ...

Random walks on the random graph [PDF]

open access: yesThe Annals of Probability, 2018
We study random walks on the giant component of the Erdős–Rényi random graph G(n,p) where p=λ/n for λ>1 fixed. The mixing time from a worst starting point was shown by Fountoulakis and Reed, and independently by Benjamini, Kozma and Wormald, to have order log2n.

Statistical analysis of random walks on network

open access: yesScientific Journal of Astana IT University, 2021
This paper describes an investigation of analytical formulas for parameters in random walks. Random walks are used to model situations in which an object moves in a sequence of steps in randomly chosen directions.

Intransitiveness: From Games to Random Walks

open access: yesFuture Internet, 2020
Many games in which chance plays a role can be simulated as a random walk over a graph of possible configurations of board pieces, cards, dice or coins. The end of the game generally consists of the appearance of a predefined winning pattern; for random ...

Ranking competitors using degree-neutralized random walks. [PDF]

open access: yesPLoS ONE, 2014
Competition is ubiquitous in many complex biological, social, and technological systems, playing an integral role in the evolutionary dynamics of the systems.

Quenched invariance principles for random walks and elliptic diffusions in random media with boundary [PDF]

open access: yes, 2014
Via a Dirichlet form extension theorem and making full use of two-sided heat kernel estimates, we establish quenched invariance principles for random walks in random environments with a boundary.
