# PriceGraphDistribution

 PriceGraphDistribution represents a de Solla Price graph distribution for n-vertex graphs where a new vertex with k edges is added at each step using attractiveness parameter a.
• The PriceGraphDistribution is constructed starting from a graph with a single vertex and at each step adding a vertex with k edges. The k edges are attached to vertices at random with weights , where is the indegree of vertex i.

The vertex degree distribution for PriceGraphDistribution is heavy tailed:
The degree distribution is heavy tailed, so logarithmic scales make it clearer:
There is great variation in the vertex degree:
