WebJun 29, 2024 · This is called the diameter of the network. In other words, the diameter of a network 1 is the maximum length of any shortest path between an input and an output. For example, in the complete binary tree above, the distance from input 1 to output 3 is six. No input and output are farther apart than this, so the diameter of this tree is also six. WebA high diameter implies a less linked network. In the case of a complex graph, the diameter can be found with a topological distance matrix (Shimbel distance), which computes for each node pair its minimal topological distance. Graphs whose extent remains constant, but with higher connectivity, have lower diameter values. WebDetails. The diameter is calculated by using a breadth-first search like method. get_diameter returns a path with the actual diameter. If there are many shortest paths of the length of the diameter, then it returns the first one found. farthest_vertices returns two vertex ids, the vertices which are connected by the diameter path. rayland tv show
