Finding communities in networks is a common task under the paradigm of complex systems. A rooted tree T with the vertex set V is the tree that can be defined recursively as follows : T has a specially designated vertex v1 ∈ V, called the root of T. A widely used approach in steady-state analysis of water distribution networks is the global gradient algorithm (GGA). If this exercise demonstrates anything, it is the investigative power of network visualization and analysis. In fact, my first post introduced such a network visualization of key driver analysis. Laurenz Cornelissen specialises in social network analysis, particularly expanding the application of network data to fields such as bot-detection and social media data. This course will introduce you to a network analysis in R, provide an as-necessary introduction to R programming and cover the basics of network analysis, including terminology; data collection/storage; and basic description.
