D^(h6ddlZdgZejdZy)Ns_metriccZttfdjDS)a[Returns the s-metric [1]_ of graph. The s-metric is defined as the sum of the products ``deg(u) * deg(v)`` for every edge ``(u, v)`` in `G`. Parameters ---------- G : graph The graph used to compute the s-metric. Returns ------- s : float The s-metric of the graph. References ---------- .. [1] Lun Li, David Alderson, John C.
