WebNov 25, 2024 · The key point to observe in the algorithm is that the number of connected components is equal to the number of independent DFS function calls. The Component_Count variable counts the number of calls. Of course, this doesn’t include the calls that are being made under the DFS() function recursively. 6. Test Run WebJan 22, 2013 · Metaphorically, a breadth-first search algorithm will look all around a vertex before continuing on into the depths of a graph, while the depth-first search will dive straight to the bottom of the ocean before looking at where it is. Perhaps one way to characterize these algorithms is to call breadth-first cautious, and depth-first hasty.
