Abstract
As one of the essential problems in information diffusion process, how to select a set of influential nodes as the starting nodes has been studied by lots of researchers. All the existing solutions focus on how to maximize the influence of the initially selected “influential nodes”, paying no attention on how the influential nodes selection could maximize the speed of the diffusion. In this paper, we consider the problem of influential nodes selection regarding to the propagation speed in social network information diffusion. We define a discrete optimization problem, called Fast Information Propagation Problem. We show that this problem is NP-hard problem when the time requirement for information propagation is exactly 1-hop. We also propose a Latency-bounded Minimum Influential Node Selection Algorithm to solve the problem in this case.
