Breadth-first search(or BFS) is finding the shortest path from a source node to all other nodes in an unweighted graph i.e. the number of edges in the paths is minimized. Breadth-first search is a core primitive for graph traversal and a basis for many higher-level graph analysis algorit...
On the All-Pairs-Shortest-Path Problem We present an algorithm, APD, that solves the distance version of the all-pairs-shortest-path problem for undirected, unweighted n-vertex graphs in time O(... R Seidel - ACM 被引量: 539发表: 1992年 New Bounds on the Complexity of the Shortest ...
The interpretation of a shortest path as the path that funnels the bulk of information flow relies on it being the least weight path (i.e., the path of least resistance) between two nodes. Indeed, all the shortest path algorithms currently available31,32 and generally implemented in graph th...
We present a solution to the fully-dynamic all pairs shortest path problem for a directed graph with arbitrary weights allowing negative cycles. We support each vertex update in $O(n^2({m log} n + { M Thorup - DBLP 被引量: 140发表: 2004年 Faster Algorithms for Rectangular Matrix Multipl...
single_source_shortest_path_length(G, 0) At face value, the path graph strikes me as a good example to probe this change as it should result in relatively large seen sets. When I run this on main and on this branch I see no appreciable difference. Now - this is all very preliminary...
