Abstract: In network design, the goal is to construct or modify a network to optimize performance measures related to the dynamics of that network. Examples of network design problems include: assigning edge weights to optimize network robustness; adding a set of edges to improve network connectivity; and identifying a set of input nodes to most efficiently drive the system to desired state. Significant work has been done to analyze the complexity of many network design problems and to develop efficient algorithms for them; however, even these efficient algorithms may not scale to the size of massive networks like online social networks, as well as physical networks like the Internet of Things. In this talk, I will examine several network design problems related to robustness and connectivity. I will present strategies for scalable network design with provable performance guarantees, including analytical solutions and algorithms that run in near-linear time. Finally, I will highlight new results on network design for diversity and polarization in social networks.
