Shortest path problem - Wikipedia
en.wikipedia.org › wiki › Shortest_path_problemThe all-pairs shortest path problem, in which we have to find shortest paths between every pair of vertices v, v' in the graph. These generalizations have significantly more efficient algorithms than the simplistic approach of running a single-pair shortest path algorithm on all relevant pairs of vertices. Algorithms [ edit]
Shortest path problem - Wikipedia
https://en.wikipedia.org/wiki/Shortest_path_problemThe shortest path problem can be defined for graphs whether undirected, directed, or mixed. It is defined here for undirected graphs; for directed graphs the definition of path requires that consecutive vertices be connected by an appropriate directed edge. Two vertices are adjacent when they are both incident to a common edge. A path in an undirected graph is a sequence of vertices such that is adjacent to for . Such a path is called a path of length from
