WebParameters-----G : NetworkX graph most_valuable_edge : function Function that takes a graph as input and outputs an edge. The edge returned by this function will be recomputed and removed at each iteration of the algorithm. If not specified, the edge with the highest:func:`networkx.edge_betweenness_centrality` will be used. WebBetweenness centrality finds wide application in network theory; it represents the degree to which nodes stand between each other. For example, in a telecommunications network, a node with higher betweenness centrality would have more control over the network, because more information will pass through that node.
