Polymer chemistry Branching Random Walk and Probability Problems from Physics and Biology OREGON STATE UNIVERSITY Edward C. Waymire JohnsonTorreyThis thesis studies connections between disorder type in tree polymers and the branching random walk and presents an application to swarm site-selection. Chapter ...
Focused random walk (FRW) is one of the most influential paradigm of stochastic local search (SLS) algorithms for the propositional satisfiability (SAT) problem. Recently, an interesting probability distribution (PD) strategy for variable selection was proposed and has been successfully used to ...
This note introduces an interesting random walk on a straight path with cards of random numbers. The method of recurrent relations is used to obtain the convergent probability of the random walk with different initial positions.doi:10.1080/00207390600712299...

Problem5.Diffusion via biased random walk(40points) In class, we derived the mean and variance of the displacement of a particle. Assume that the particle now moves to the right twice as frequently as it does to the left. That is, ...
probability. If the site is occupied, the random walk decides to jump to the right with probabilityand to the left with probability. Let us denotethe trajectory of the random walk. We are going to revisit the definition of the random walk on Sect.2.2where a useful graphical construction is...
walk to one of the eight adjacent sites approximately 66.8% of the time; 95.7% of jumps are within a distance of 2 sites. The random-variate generator for the jump distancesrin Eq. (2) is derived from a probability density function of the form\(\phi (r)=A/r^4\), where the ...

In the case of non-local random walks the model is mainly driven by β—with segregation being the lowest for values close 0 where there is equal probability of transitions between nodes regardless of distance. Full size image In the preferential random walk model, the segregation index is ...
