WebDec 11, 2024 · Basically, it is the average of all the shortest lengths between any two nodes of a graph. In case two nodes are not connected, the length between them is set to zero (i.e., d ( v i, v j) = 0 ). I find this definition not meaningful because a connected graph may have the average path length higher than an unconnected graph.
