Graphshortestpaths
WebTrue or false: For graphs with negative weights, one workaround to be able to use Dijkstra’s algorithm (instead of Bellman-Ford) would be to simply make all edge weights positive; … 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.
