WebApr 29, 2024 · 1 Answer. Sorted by: 1. If n is the number of vertices of your graph, then the library internally creates an n by n matrix to store all shortest paths. So, yes, the memory consumption is substantial. This is due to the fact that internally the library uses an all-pairs shortest-path algorithm such as Floyd-Warshall or Johnson's algorithm. WebMar 24, 2024 · The graph diameter of a graph is the length max_(u,v)d(u,v) of the "longest shortest path" (i.e., the longest graph geodesic) between any two graph vertices (u,v), …

WebJan 3, 2024 · Floyd Warshall Algorithm. Floyd Warshall algorithm is a great algorithm for finding shortest distance between all vertices in graph. It has a very concise algorithm and O (V^3) time complexity (where V is number of vertices). It can be used with negative weights, although negative weight cycles must not be present in the graph. Webin such graphs can be solved in O˜(nω) time – the best al-gorithm is by Zwick [36] running in O(n2.54) time [25], and hence for directed unweighted graphs diameter and radius can be solved somewhat faster than APSP. For undirected unweighted graphs the best known algorithm for diameter and radius is Seidel’s O˜(nω) time APSP algorithm [32].
