Compute node degrees and degree distributions in biological interaction networks and understand these topological descriptors.

What you will implement

Implement node degrees and degree distributions on simple undirected graphs; synthetic-network exercises do not establish that real biological networks are scale-free.

• 114. Biological Interaction Networks: Node Degree and Degree Distribution

  Represent an interaction network as nodes and edges, compute each node's degree, and distinguish a node's degree from the network's degree distribution.

  Implement node degrees and a dense degree distribution for a simple undirected graph, with explicit rules for duplicate edges, self-loops, isolated nodes and invalid input.
