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. WebSince G is a directed graph, d is not symmetric, and d(i,j) corresponds to the distance between nodes i and j.The Inf values in d correspond to nodes that are unreachable. For example, since node 1 has no predecessors, it is not possible to reach node 1 from any other node in the graph. So the first column of d contains many Inf values to reflect that …

In other words, this method computes the 'longest shortest path'. Two special cases exist. If the graph has no vertices, the diameter is 0. If the graph is disconnected, the diameter is Double.POSITIVE_INFINITY.
