Reducing Search Lengths with Locally Precomputed Partial Random Walks
Random walk network search resource location search length

Abstract: Random walks can be used to search a complex networks for a desired resource. To reduce the number of hops necessary to find the resource, we propose a search mechanism based on building ran...

Abstract: We investigate the relation between simple random walks on repeated barycentric subdivisions of a triangle and a self-similar fractal, Strichartz hexacarpet, which we introduce. We explore a...

A n-step Pearson-Gamma random walk in dstarts at the origin and consists of n independent steps with gamma distributed lengths and uniform orientations. The gamma distribution of each step length has ...

Abstract: Consider an N-dimensional Markov chain obtained from N one-dimensional random walks by Doob h-transform with the q-Vandermonde determinant. We prove that as N becomes large, these Markov cha...

Quantum random walks (QRWs) can be used to perform both quantum simulations and quantum algorithms. In order to exploit this potential, quantum walks on different types of graphs must be physically im...
Matrix valued Szego polynomials and quantum random walks
Matrix valued Szego polynomials quantum random walks
font style='font-size:12px;'>
2010/4/8
We consider quantum random walks (QRW) on the integers, a subject that has been considered in the last few years in the framework of quantum computation. We show how the theory of CMV matrices gives a...
Some Limit Theorems for a Particle System of Single Point Catalytic Branching Random Walks
Renewal equation branching particle system scaling limit
font style='font-size:12px;'>
2007/12/10
We study the scaling limit for a catalytic branching particle system whose particles perform random walks on ${\Bbb Z}$ and can branch at 0 only. Varying the initial (finite) number of particles, we g...
Variable Survival Exponents in History-Dependent Random Walks: Hard Movable Reflector
Variable Survival Exponents History-Dependent Random Walks Hard Movable Reflector
font style='font-size:12px;'>
2010/10/28
We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for historydependent random walks, and analyze a new example, the hard movable partial reflector. These ...
