Mixing of the symmetric beta-binomial splitting process on arbitrary graphs

Richard Pymar, Nicolás Rivera

We study the mixing time of the symmetric beta-binomial splitting process on finite weighted connected graphs with vertex set , edge set and posit…

Distributed Averaging in Opinion Dynamics

Petra Berenbrink, Colin Cooper, Cristina Gava +4

We consider two simple asynchronous opinion dynamics on arbitrary graphs where every node has an initial value . In the first process, the NodeModel, at each time step…

Asymptotic behaviour of the noisy voter model density process

Richard Pymar, Nicolás Rivera

Given a transition matrix indexed by a finite set of vertices, the voter model is a discrete-time Markov chain in where at each time-step a randomly chosen vert…

Diversity, Fairness, and Sustainability in Population Protocols

Nan Kang, Frederik Mallmann-Trenn, Nicolás Rivera

Over the years, population protocols with the goal of reaching consensus have been studied in great depth. However, many systems in the real-world do not result in all agents event…

Multiple Random Walks on Graphs: Mixing Few to Cover Many

Nicolás Rivera, Thomas Sauerwald, John Sylvester

Random walks on graphs are an essential primitive for many randomised algorithms and stochastic processes. It is natural to ask how much can be gained by running multiple rando…

Kernelized Stein Discrepancy Tests of Goodness-of-fit for Time-to-Event Data

Tamara Fernandez, Nicolas Rivera, Wenkai Xu +1

Survival Analysis and Reliability Theory are concerned with the analysis of time-to-event data, in which observations correspond to waiting times until an event of interest such as…
