Tīmeklis2002. gada 19. febr. · Abstract. We describe some new exactly solvable models of the structure of social networks, based on random graphs with arbitrary degree distributions. We give models both for simple unipartite networks, such as acquaintance networks, and bipartite networks, such as affiliation networks. We compare the … TīmeklisLet G p be a random graph on 2 d vertices where edges are selected independently with a fixed probability p > ¼, and let H be the d-dimensional hypercube Q d. We answer a question of Bollobás by showing that, as d → ∞, G p almost surely has a spanning subgraph isomorphic to H .
