PHYS 597A, CMPSC 497E: Graphs and networks in sys- tems biology Homework assignment 5, due Tuesday Oct. 6 1. The Sept. 24 lecture surveyed a number of graph processing and visu- alization tools. Install one of them and use it to draw and analyze a graph. Provide a screenshot of your work and a two-three paragraph overview of what the software/library can do, what you did with it, and your assessment of the process of accomplishing the desired outcome.

Answer the following questions: a) At what connection probability you expect the existence of (i) a tree with six nodes, (ii) a cycle with six nodes, and (iii) a completely connected subgraph with six nodes in a large ( N →∞ ) random graph? b) A random graph has a connected component that unites a large fraction of its nodes. What is our expectation for the graph’s average degree? c) A random graph has the following degree distribution: P ( k ) = C k 11 p 1 3 P k p 2 3 P 11-k (1) What is the number of nodes and the connection probability? What is the average degree of this graph? 1...
