Which people should we immunize, to prevent an epidemic (e.g., Ebola) as fast as possible? Which users should we target to in order to achieve an effective promotion campaign for our product? How do opinions or rumors get formed and propagate in social media (e.g., Twitter)? The modeling of propagation in various contexts (populations, materials, computer networks, social networks) has seen great progress in its formalization in recent decades. The goal of this class is to familiarize students with the classic techniques that will allow them to reproduce, predict and anticipate the effects of a virus or information propagation in real-life situations. Two main approaches will be considered in this course: propagation in a homogeneous population, leading to continuous modeling; propagation in a structured population with an underlying graph layer. In the latter case, the properties of the propagation phenomenon depend on the graph structure.
