Returns the s-metric of graph.
The s-metric is defined as the sum of the products deg(u)*deg(v) for every edge (u,v) in G. If norm is provided construct the s-max graph and compute it’s s_metric, and return the normalized s value
G (graph) – The graph used to compute the s-metric.
normalized (bool (optional)) – Normalize the value.
s – The s-metric of the graph.
- Return type
