Activity Overview
In "Under Pressure," Don's team is looking for a terrorist cell. Subgroups within the cell are connected by minimum contact, so the entire cell is not exposed if one group is discovered. Charlie explains that the structure of a terrorist cell is like a complex network, made up of nodes and edges, and that the cell structure can alter over time. In this activity, students will study how to measure certain statistics of a network and how changes in the network influence these measurements.
