Random walks under slowly varying moment conditions on groups of polynomial volume growth, with laurent saloff-coste proceedings of the conference . We define a reinforced urn process (rup) to be a reinforced random walk on a state space of urns and we show its partial exchangeability when it is recurrent, a rup. A random walk is a mathematical object, in brain research, random walks and reinforced random walks are used to model cascades of neuron firing in the brain. 1 introduction reinforced random walks have been studied extensively since the introduction of the (linearly)-reinforced random walk of coppersmith and diaconis [6.

Edge-reinforced random walks produce a co-evolution of the network with the dynamics of the walkers at time t the walker is on the red node and has already visited.

A discrete random walk that avoids previously visited vertices for an exponentially distributed time interval to the theory of reinforced random walks.

  • We study vertex-reinforced-random-walk on the complete graph with weights of the form $w(n)=n^\alpha$, with $\alpha1$ unlike for the edge-reinforced-random-walk.
  • The weakly reinforced random walk (wrrw) on the one-dimensionalinteger lattice zstarts from the origin of the lattice and at each step it jumps to aneighbouring site.

This simulation is made using a a new parallel version of the current reinforced-random walk model implemented in c by kristoffer jonsson and david jäderberg. 568 r durrett et al the question is whether {xn} (which by itself is non-markovian) is recurrent or transient we only consider the case when g is a regular b-ary tree.
