Weintroduce a model for information spreading among a population ofN agents diffusing on a square L×L lattice, starting froman informed agent (Source). Information passing from informed to unawareagents occurs whenever the relative distance is 1. Numerical simulationsshow that the time required for the information to reachall agents scales as N^–L, where alpha and beta arenoninteger. A decay factor z takes into account the degenerationof information as it passes from one agent to another;the final average degree of information of the population [script I] _av(z)is thus history dependent. We find that the behavior of_av(z) is nonmonotonic with respect to N and L anddisplays a set of minima. Part of the results arerecovered with analytical approximations.
