k_residue
(G, k)¶ Return the k-residue of G.
The k-residue of a graph G is defined as follows:
\[\]rac{1}{k}sum_{i=0}^{k-1}(k - i)f(i)
where f(i) is the frequency of i in the elmination sequence of the graph. The elimination sequence is the sequence of deletions made during the Havel Hakimi process together with the zeros obtained in the final step.
- G : graph
- A Networkx graph.
- kResidue : float
- The k-residue of G.
