Social influence and influence diffusion has been widely studied in online social networks. However, most existing works on influence diffusion focus on static networks. In this paper, we study the problem of maximizing influence diffusion in a dynamic social network. Specifically, the network changes over time and the changes can be only observed by periodically probing some nodes for the update...
The localization principle and error source of DV-Hop algorithm which is classic self-localization algorithm in wireless network are introduced in this paper. Aiming at the disadvantage of DV-Hop algorithm on localization accuracy, an improved scheme by modifying the average hop distance is proposed. The simulation results show that the comprehensive properties of the improved algorithm (including...
One of the special variants of VRP model, the Heterogeneous Fixed Fleet Vehicle Routing Problem (HFFVRP) is discussed in this paper. The objective is to minimize the total delivery cost, including vehicle fixed cost and traveling variable cost. An effective parallel improving tabu search algorithm is developed to solve the model. Multiple neighborhood searching strategy and parallel improving technique...
