Abstract: Networks can be found everywhere in the modern world: application areas are abundant and diverse, spanning the domains of big data and physical/virtual complex systems. In general, networks reflect how elements of a system/dataset are connected and interact with each other. Network science is an interdisciplinary field that studies these complex networks from various perspectives. 'Descriptive' mathematical modeling of networks may reveal interesting connectivity patterns that characterize a complex system/dataset. In addition, an increasingly important task is optimizing certain properties of a networked system, for instance, by making optimal decisions on design and/or enhancement of a network. Such problems can be referred to as 'prescriptive modeling' or 'network engineering'. This presentation will address the following broad questions. (i) Can we identify large “well-connected” clusters/communities within a network? (ii) Can we design well-connected networks with certain guaranteed resilience properties? (iii) What are “critical elements” of a network that are responsible for its integrity/vulnerability? (iv) Can we solve these problems to optimality? Modeling and computational aspects of these problems will be discussed.
