WebOne algorithm for finding the shortest path from a starting node to a target node in a weighted graph is Dijkstra’s algorithm. The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph. Dijkstra’s algorithm, … 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.
