Breadth First Search - Part 1

[@Jajdjejwi28]

I wasted hours at my uni with professors that overcomplicated these search algorithms. You sir saved me big time!

I relate

[@abhilamsal7185]

Breadth First Search applies goal test to each node when it is generated rather than when the node is selected for expansion. Therefore, once the algorithm determines shallowest goal node, it stops the search. By following your explaination, the time complexity of BFS comes around in the order of O( b^ (n+1) ). However, if the nodes were to be tested for goal nodes when they were generated rather than when selected for expansion, time complexity becomes O(b ^ n) since whole layer of nodes at depth n would be expanded before goal was detected. b -- branching factor n -- depth of shallowest goal node.

I love John's Lecture so helpful when it comes to explaining, I would love to have him as my AI Professor. anyways Thanks Dr John

[@mariagabrielagarciaarroyo4733]

Loving this channel, super well explained. Thank you!

[@raphaellmsousa]

Congratulations for your explanation! It was the best one for this topic for me!

[@kelvinmonari5512]

You are the best profesor ever

[@limitless1692]

Wow simple and clear Thank you Sir Much appreciated :)

[@johnlevine2909]

You're very welcome!

[@benaya6]

the best explanation I found so far...thank you sir

[@syntaxerror2144]

Amazing work brother!

[@franchello1105]

A couple of drawbacks to bring up. Not guaranteed to find the least costed path from S to a Goal State. Also would use a ton of storage to maintain all the current unexpanded nodes. Back in college we had to solve the canibal missionary problem using DFS, because the storage required would grow exponentially if BFS is used.

Thanks. This is very helpful.

[@yourdoom9868]

Thanks for the explanation sir!

[@yourfellowmuslimyagi2065]

Excellent explanation

[@hosseinjavoon]

thank you it was great ❤🌹

[@gabethebabe3840]

WOW great video!

[@AsomyTraiget]

Thanks

[@abhirustagi6969]

thankyou sir!!! very well explained

[@ruixincheng6201]

great explanation!!! could you please upload more videos about Neural networks and probability problems? such as Bayes networks,approximate inference and CNN

[@tzaswit]

Thank you

[@hashithakularatne3646]

don't we need to add all the visited letters for that path?

[@sknganga3633]

This guy saving my degree

[@jerushanmoodley2641]

Well explained

[@nadaali5]

thank u

[@amirhoxha6231]

smart fella

[@kjohari_]

Missing your videos sir

[@ibrahemnasser2744]

Wrong! Correct Path is: ABDG1

[@johnlevine2909]

That's the order the nodes get visited in, but the path is the route that the agent needs to take to get to the goal.
