An efficient algorithm to generate random uncorrelated Euclidean distances: the random link model

Abstract: A disordered medium is often constructed by N random points independently and identically distributed in a d-dimensional hyperspace. Characteristics related to the statistics of this system are known as the random point problem. As d → ∞, the distances between two points become independent random variables, leading to its mean field description: the random link model. While the numerical treatment of large random point problems poses no major difficulty, due to Euclidean restrictions the same is not true for l… Show more

“…The expected number of points in a volume V d is λ = ρV d , where ρ is the point density. This disordered medium, although unlimited, can be represented computationally as a d-dimensional hypercube, containing N coordinates randomly distributed with uniform probability density function (pdf) along each edge (random point problem [1]). This is a possible way to construct a disordered medium, where, distances among the points are not fixed, but vary statistically.…”

“…Também neste Capítulo, apresentamos os aspectos estáticos e dinâmicos do algoritmo da caminhada do turista, de forma que a dinâmica consiste em mover-se progressivamente até que se fique aprisionado em pontos próximos, sobre uma tabela de vizinhança. Essa tabela é ordenada pela métrica euclidiana, a qual, se alteradas permite examinar a dinâmica do turista em outros dois modelos: como os modelos de ligações aleatórias e mapeamento aleatório [30,31].…”

“…O número de pontos esperado em um volume V dé λ = ρV d , onde ρé a densidade de pontos. Esse meio desordenado, apesar de ilimitado, pode ser representado computacionalmente como um hipercubo d-dimensional, que contém N coordenadas aleatoriamente distribuídas com função densidade de probabilidade uniforme em cada aresta (random point problem) [34]. Essaé uma maneira de construir o meio desordenado, na qual, as distâncias entre pares de pontos deixam de ser regulares e passam a variar estatisticamente.…”
