WebA central problem in algorithmic graph theory is the shortest path problem.One of the generalizations of the shortest path problem is known as the single-source-shortest-paths (SSSP) problem, which consists of finding the shortest path between every pair of vertices in a graph. There are classical sequential algorithms which solve this problem, such as … WebDetails. The shortest path, or geodesic between two pair of vertices is a path with the minimal number of vertices. The functions documented in this manual page all calculate …

WebAlthough this gives us an \mathcal O (NM) O(NM) solution, there is a simpler solution using 0/1 BFS! Consider the graph with an edge between each pair of adjacent cells with tracks, where the weight is 0 if the tracks are the same and 1 otherwise. The answer is simply the longest shortest-path from the top left cell.
