Breadth-first search (BFS) Breadth First Search (BFS) algorithm traverses a graph in a breadth ward motion and uses a queue to remember to get the next vertex to start a search, when a dead end occurs in any iteration. As in the example given above, BFS algorithm traverses from A to...
[i] == 1 && lstVertices[i]->visited == false) return i; } return -1; } void breadthFirstSearch() { int i; //mark first node as visited lstVertices[0]->visited = true; //display the vertex displayVertex(0); //insert vertex index in queue insert(0); int unvisitedVertex; ...
Breadth First Approach The BFS algorithm begins at a source hub and investigates its neighbours, recently moving to another level of neighbours. Use the circuit information structure to keep track of which hubs you visit. On each cycle, the computation visits a hub, marks it as finished, and ...
