Dear all

Function graph_tool.generation.price_network has a parameter named constant factor.

According to graph-tool documents, for undirected graphs, the degree distribution of generated graph should be .

However, when I use different constant factors to generate different price network graphs, I notice that all graphs have a same degree distribution. It seems that different constant factors have no influence on the degree distributions.

For example:

g1 = gt.price_network(100000, m=3, directed=False)

g2 = gt.price_network(100000, m=3, c=-0.9, directed=False)

For g1, the degree distribution should be .

For g2, the degree distribution should be .

When I draw the degree distributions of the two graphs, they are almost the same.

So, does the parameter constant factor  really change the graph degree distribution?
