Diffusion occurs in various contexts and generally involves a network of entities and interactions between entities. Through these interactions, some property, e.g. information, ideas, etc., is spread through the network. This paper presents a general model of diffusion in dynamic networks. We simulate the diffusion of evacuation warnings in multiple(More)
