Dijkstra's algorithm in 3 minutes 

SO TRUE HAHAHA!!!!! lmao

On point ._.

气死我了，被抓包了

30 min*

So damn true, my exam is in twenty minutes lol.

same lol

Fucking same, fuck uni teachers

same here :D

same here :D@@burstfireno1617

That's weird honestly

James Clark Thanks, James. More coming soon.

An implication of Parkinson's Law.

what kinda teacher teaches dijkstra's algorithm for a whole semester?

@@ROFEL he meant everything his University or college covered in a semester,he is right though, sometimes

There isn't anything you can't learn faster and more easily at home with the internet - all you need is motivation.

​@@loot6 so true

Excuse me for using your top comment, but I have to let people see this: Sorry, but this algorithm is incomplete and not capable of solving a problem that my professor gave me. It works for the simplest matrices, but that's that. As a proof try to solve this exercise as said in the video: find the shortest route from f to c. The matrix is: . a b c d e f a 0 2 4 0 0 5 b 9 0 0 7 5 0 c 4 3 0 8 0 0 d 0 3 9 0 0 6 e 6 0 0 5 0 0 f 0 5 0 6 3 0 The solution should be 13 (f-e-a-c) but with this algorithm you will never obtain it.

worked for me

There is an error in this explanation, I actually learnt the base of the algorithm here since the explanation is very simple and I came to find that it wasn't completely right. The error is when he says that we choose the edge with the minimal cost in order to visit a certain node, that's not the case, we have a list of the unvisited nodes and from all those nodes, the algorithm says that the next node to be visited is the node with minimal TOTAL distance to the origin, remember every visited node tries to update the adjacents nodes. You wrote this a long time ago, but I hope new viewers don't fall for the same mistake I did when I only based in this explanation.

but if that's the case where's his mistake? he always chooses the "cheaper" one realtive to the origin? or are you saying that his wording was poor?

I believe he's talking about the wording. The lack of explanation about how he did what he did for the sake of simplicity.

hope you got selected

Update?

13 hours is a lot of time dude

nice now 3 years later i got an exam tomorrow. Hope i do really well.

Broo....

13 hrs. You're like a baby. Watch this S I X H O U R S

Nice

A lot of them become teachers bc they’re really intelligent and hardworking, not because they’re actually good at teaching

@@BossKing1243 Can't agree more, most of them are good at doing research rather than teaching us

@@BossKing1243 Yup exactly.

Also classes move at the pace of the slowest learner. While videos go at superspeed, knowing you can just rewind a section you don't understand.

do you mean review?

why tf do you have access to RU-vid during exam

Happens to the best of us 😴

Danke fürs zuschauen!

welcome! crush it

💪🏼❤️

LMAO I'm here the day before my ALevel CS exam.
