Breadth First Search Algorithm

This is one of the important Graph traversal technique. BFS is based on Queue data structure.
Analysis:
The time complexity of BFS using Adjacency list is O(V + E) where V & E are the vertices and edges of the graph respectively.

great video. accent didn't phase me at all stop complaining people this is free information! be thankful

even your accent is also damm horrible

[@NippyWolf]

I have seen alot of videos about this subject, but you video is by far the most simple and most clear explanation. Also liked your DFS video. Thank you!

[@ammarseud5461]

Watched on x2 speed with no sound, understood everything. The video is just that good :)

[@gogateiit]

Thanks Anny :) Please share "Breakfast Search" with your friends and keep watching.

[@brendamoragwa2474]

I learnt a lot in this video. Thank you so much❤

[@himanshukashyap6336]

I LITERALLY GOT SCARED WHEN HE SAID, "THAT'S IT, DONE!". ANYWAYS, IT WAS REALLY HELPFUL, SIMPLE LANGUAGE, EASY TO UNDERSTAND.

The best video so far. Everytime I get confused between DFS and BFS I always come here!! Thank you so much

how can someone dislike this? its ample explanation for this topic .

[@aditinarware9843]

Very well explained, both DFS and BFS. Simple and clear!

[@deejay5627]

Thank you so much! This and your Depth-first search video have been very helpful and easy to understand. In fact I'd prefer these over my school notes!

[@shashwatkansal6786]

Very clear, very simple, couldn't have had a better explanation. Thanks a lot!

[@Monyamu]

Great video, helped me a lot in visualizing the progress of the algorithm. I learned it a tiny differently however, regarding the first step, i don't know if its a mistake here, or not.
A is added to the queue before the loop, (the video starts from here--->)marked as visited, added to the output sequence.
We take A as currently working node (this is the time, when it's removed from the queue, not shown here in the video), then take it's unvisited neighbours, everything else goes as in the video.
If you learned it like this, that might be those declarations before the double loop in the structogram.

[@krlwshu]

I wasted 2 hrs in a lecture trying to make sense of what you explained perfectly in 4 minutes. Thank you.

[@jackchun8767]

Clean and clear explanation, Thank you so much ! Looking forward to see more of your tutorial video :)

[@AdamGreenhill]

Thanks man! This + DFS helped!

[@azzarox6661]

Thanks for the refresher, needed to implement this for an assignment and couldn't remember how. This really helped!

[@viduraweerasinghe6624]

Thank you very much ,,, very clear explanation !!!

[@ParameswaraReddyBanthikatla]

Best simplest possible explanation. Thank you

[@yanivgardi9028]

thanks. it's a good video, but i think it's worth mentioning that when running a BFS starting from vertex A, you actually create a Tree structure (sub-set of the edges), with a root A, that connects all vertexes in the graph to vertex A with the shortest path

[@iamusmanshabbir142]

Best simple easy graphical representation i'was looking for

[@luc1179]

Absolutely crystal clear!

[@rahulmarkonda]

Simple yet Superb explanation. Thank you.

[@Zinic_]

Another way to look at it: Start with A. One step away from A is B and S. Two steps away from A is C and G. Three steps away from A is D E F H.

[@almind2894]

thanks!

[@majdayoub2344]

But what are the complexities of both ways?

[@SCShield]

Breadth-first search and depth-first search are both linear algorithms.

[@cryptoanalyst5058]

[@vickylance]

I am clearly understanding the algorithm but not able to write a program and also not able to understand the program already writtern by someone else ..... I definitely need a video which explains the algorithm with the help of a program.

[@gustavoturm]

Take a look at Dieter Jungnickel's "Graphs, Networks and Algorithms" and also at Sedgewick's "Algorithms".

your material is very information . i have some questions related to your topic can u plzzz tell me Why BFS take a lot of space than DFS, although their space complexity is same? and why we implement BFS by only using queue?

[@samuelgosselin5150]

great video thanks for the short length

[@CamKnoppMusic]

Great vid. Nice and simple.

[@badwaikrohit]

Nice explanation! But if you could add little about the algo's complexity and explain it, then it could have made this very useful.

[@craumm]

When you are S, you check A as well, and since it is visited, it is not added on the Queue. You discussed this with E, F and H. Nice video

[@supernalmalang749]

i can understand it very well..... thank you so much

[@def__init]

POP IT OFF I love it thank you

[@sindhuchinniah4363]

Thank you so much. It was helpful.

[@MrPali1]

helpful, but it would be nice to know the path, say, if H was the end node, how do you find the shortest path?

[@bhupeshpant8830]

very helpful and easy as compared to any other technique for BFS.

[@shyamasishgupta5206]

Thanks For the video. But i have a doubt. If the empty queue is the ending condition for the algorithm, then after Dqueue of 'S', the queue was empty. Why the algorithm didn't stop in that time itself?

[@TaraArya92]

Nice Explanation, Thanks you so much....

is it only use for graph traversals, or also directed graph ?

hey an awesome awesome awesome video :) :) thanks alot for your DFS and BFS algos. you've explained it well :) :) i wish you were the professor of my college :D.

[@pavarayaa]

In Breadth First Search (BFS) Algorithm, the search should start from the root node which is in level 0, isn't it? And then goes level by level from left to right.
