Please combine any code together with text responses in a single upload file to Lemida by the deadline.
1. Read in the file uploaded with the assignment airport-network.gml. You can read the file into network using the network command nx.read_gml(‘airportnetwork.gml’), where the argument in the middle is the filename.
a. Make a log-log plot of the degree distribution of this network. Also
compute its global clustering coefficient using the command
nx.transitivity(G).
b. Make an Erdos-Renyi Graph with the same average degree as this network
and plot its degree distribution. You may use the network command
nx.erdos_renyi_graph(), with the appropriate values of N and p (you will
have to calculate the correct p). Compare this to the actual degree
distribution
c. Using nx.configuration_model(G), create a network with the same degree
distribution as the original network and compare its clustering coefficient
value.
2. Consider an Erdos-Renyi network with N=6,000 nodes, connected with
probability p=0.0001.
a. What is the expected number of links L?
b. In what regime is the network (critical, subcritical, supercritical, fully
connected).
c. Assuming the same value of p, what value of N would lead to a network
with an average degree of k=10.
3. Degree and components
a. Consider an undirected network of size N in which each node has exactly
degree k = 1 (not average degree k=1!). What has to be true of N for this
network to exist? What is the degree distribution of this network? How
many components does this network have?
b. Consider now a network in which each node has degree k = 2 and
clustering coefficient C = 1. What has to be true of N for this network to
exist? Describe what this network looks like.
