Graph Theory

In this class we covered the basics of Graph theory and introduced some of it's fundamental concepts:

  • Adjacency Matrix
  • Degree Distribution
  • Paths and Cycles
  • Clustering Coefficient
  • Network Diameter
As an application of some of these concepts, and as a way of showing their relevance in a practical application, we analyzed the Watts and Strogatz Small World network.
