WebIn the general case, BFS can’t be used to ﬁnd shortest paths, because it doesn’t account for edge weights. If every edge weight is the same (say, one), however, the path that it … WebIn BFS, we initially set the distance and predecessor of each vertex to the special value ( null ). We start the search at the source and assign it a distance of 0. Then we visit all the neighbors of the source and give each neighbor a distance of 1 and set its predecessor to be the source. Then we visit all the neighbors of the vertices whose ...
