When a dead end occurs in any iteration, the Breadth First Search (BFS) method traverses a graph in a breadthward motion and utilises a queue to remember to retrieve the next vertex to start a search.
As in the example given above, BFS algorithm traverses from A to B to E to F first then to C and G lastly to D. It employs the following rules.
- Rule 1 − Visit the adjacent unvisited vertex. Mark it as visited. Display it. Insert it in a queue.
- Rule 2 − If no adjacent vertex is found, remove the first vertex from the queue.
- Rule 3 − Repeat Rule 1 and Rule 2 until the queue is empty.
| Step | Traversal | Description |
|---|---|---|
| 1 |  | Initialize the queue. |
| 2 |  | We start from visiting S (starting node), and mark it as visited. |
| 3 |  | We then see an unvisited adjacent node from S. In this example, we have three nodes but alphabetically we choose A, mark it as visited and enqueue it. |
| 4 |  | Next, the unvisited adjacent node from S is B. We mark it as visited and enqueue it. |
| 5 |  | Next, the unvisited adjacent node from S is C. We mark it as visited and enqueue it. |
| 6 |  | Now, S is left with no unvisited adjacent nodes. So, we dequeue and find A. |
| 7 |  | From A we have D as unvisited adjacent node. We mark it as visited and enqueue it. |
At this point, there are no unmarked (unvisited) nodes. However, according to the algorithm, we must continue dequeuing in order to obtain all unvisited nodes. The program ends when the queue is empty.

This is my first time pay a visit at here and i am actually pleassant to read everthing at one place.
With havin so much written content do you ever run into any problems of plagorism or copyright infringement?
My website has a lot of exclusive content I’ve either
written myself or outsourced but it looks like a lot of it is popping it up all over
the internet without my agreement. Do you know any ways to help protect against content from being
ripped off? I’d truly appreciate it.
Today, I went to the beach front with my children. I found a sea shell
and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She put the
shell to her ear and screamed. There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
