I like to think about stooge sort as a bubble sort that suffers from anxiety and is obsessed with the fear that the part of the list he already sorted is shuffled when he is not looking, so he is always double, triple or quadruple checking
That’s quite a reasonable assessment. As the sort deals with larger and larger arrays, the vast majority of comparisons done become entirely redundant because it had already sorted that area and hasn’t touched it since.
@@drinks_mayoAnimating it is probably the easy part. There gets a point in a CGI animation crew's life where they can't hand craft the animation anymore and have to write some custom animation software code that can do the incredibly detailed stuff, so the animators can take care of the bigger picture instead. This could have four or five sets of animations that could be chained and dynamically switched between. Then some code would actually calculate a sort and record every step, and the animation software would copy that recorded scenario. The animators would make the code look pretty, but the code would piece everything together. It would take little time to animate 1000 balls. They could make the rendering last until the end of the universe if they wanted to. And they wouldn't have to give any input for more than the first 30 seconds of the animation, and then the last 30 seconds of the animation. Also, there is no way you could pay anyone to animate this video. They probably did code something that would chain these animations together, regardless of the ball shuffle animation.
Quantum bogosort: Start with an unsorted array. Shuffle the elements randomly If it's solved, print the array. If it's unsolved, destroy the universe. All remaining universes will have had an instant sorting.
@@derekliu793 Isn't that the one which Randomizes like Bogo sort but instead of randomizing the whole thing, it randomizes one item at a time, and once the item is correct, it randomizes 2 items all until it reaches a point in randomizes items at a time?
Stooge sort be like: "okay this is done, next one" "hmm, done" "wait lemme make sure its done" "seems done" "hold on is everything done" "looks like it" "ok next one" "hmm done"
Who will right Shakespeare's hamlet first? One human with really bad ocd double checking everything or a monkey on typewriter that restarts after every mistake
However the difference between stooge and bogo is that if they are both fed with an already-sorted list, stooge will still waste your time, but not bogo
As much of a silly joke Bogo sort is, I feel like there still is something you can learn from it and other terribly slow algorithms. By learning about how they operate, you can see their design and thus avoid similar mistakes, such as unnecessary looping or relying on a mechanism that isn't reliable. I've seen such mistakes a lot, and it can greatly impact the performance of code, as demonstrated here (In extremes, but still), so taking note of what joke algorithms do that make them a joke can help you not do those things when you're trying to make serious code
That both is really interesting but also absolutely ridiculous. I mean on one hand it'd make sense considering how bogo sort works, but on the other hand the fact its time range is from 0 to infinity is bewildering.
I like how the stooge sort bot is just looking around mindlessly while waiting for bogo sort to finish, but it's been established already that they have incredibly poor eyesight so he's not really seeing anything.
Notes: The expected number of comparisons that this bogo sort will make to sort 10 balls is 12,829,490, Adding one more ball brings this number all the way to 152,369,679 ! Also: The robot in this video got lucky, as on average six balls will take bogo sort 1734 comparisons!
Worst Case Scenario: If there are n items, then there will be n! (n factorial=1x2x3x4x...x(n-1)x n) permutations until he finds the correct one! If there are 170 items, then he will have more than 1.80x10^308 permutations
I know you were skeptical about doing a video on Bogosort back when, but the visualization you came up with for it is honestly amazing, and the fact that you went to the trouble to animate over 30 minutes of footage of just Bogosort shuffling the sequence over and over again is doubly amazing. Perhaps you just feel like you caved to what the mob wanted, but honestly? I say bloody good show and if you ever did another one it could be literally anything and you'd have absolutely nothing to prove. Also, fun fact - the probability of randomly getting a six-object sequence in its correct order at least once after randomizing the sequence 345 times is only around 38%. So for those who joke that Bogo is the fastest sort if it gets lucky, consider that what you see in this video is actually _pretty good_ by Bogosort standards. You need around 3,315 trials before you have a greater than 99% chance of the sorted sequence appearing at least once.
I hope they used something to automate the animation because I'm willing to bet at least 5 animators shot themselves before they even managed to convince someone to animate it.
Bogosort was my first introduction to why time complexity really matters. With a small number of elements, it doesn't matter if you use bubble sort or quick sort or whatever, but you try a bogosort on just 15 elements and you might as well just sort them yourself lol.
Quantum bogosort is a hypothetical sorting algorithm based on bogosort, created as an in-joke among computer scientists. The algorithm generates a random permutation of its input using a quantum source of entropy, checks if the list is sorted, and, if it is not, destroys the universe. Assuming that the many-worlds interpretation holds, the use of this algorithm will result in at least one surviving universe where the input was successfully sorted in O(n) time.
@@84updownI work in aviation-related field and bogo sort is literally sorted there all the time. The reason behind it is that embedded systems like planes need to preserve memory.

My favorite sort algorithm is one I call thermodynamic sort: Background: Physics show that the universe likely will reach a time where its energy is evenly distributed everywhere, and thus, nothing happens - time is frozen, forever. This is known as the heat death of the universe. Algorithm: 1. Define some time span T 2. Wait for T time 3. Check if universe has reached its heat death. If so, you're finished. If not, return to step 2 (you can also return to step 1 and redefine T, the algorithm's correctness remains) Proof: By the time the algorithm halts, the universe has reached its heat death and no form of intelligent life exists. With no brains to think it, the concept of "comparison" ceases to exist and thus no element is less than a preceding one. The list is ordered.
However, there would also be no way for the algorithm to continue existing as no one could actually check if the heat death has occured, as if it did then there would be no minds to proccess that it occured.
if you just destroy your computer then there will be no more data no data means an empty set, which is sorted plus, given that destroying a computer does not take more/less time depending on list length this algorithm should take O(1) time.
I saw a comment on an earlier video from about 5 years back about Bogo sort and I thought that I would never be able to see the glorious inefficiency of it rendered in an udiprod video. I was wrong, and I'm so glad I was. (Now I just want an endless live stream of miracle sort!!)

when i clicked on this video i was like " is this really gonna be a 40 minute video about bad sorting algorithms. its just an elaborate troll of bogo sorting
@@adrihooijer536 the probability is 1/6! (6x5x4x3x2x1), but a lot of time in probability you use cases as probability and in the other way (because probability is the inverse of the cases (when all the cases are equally possible and only 1 case wins))
I love how Bogo sort has two extreme cases. - It randomizes the list once and is instantly correct. - It literally takes an infinite number of attempts to be correct. Mathematically, both of these are technically possible outcomes.
with most other sorting algorithms, there is usually some way, some arrangement of items you can use to maximize swaps, such as giving Stooge Sort a list that's inverted. but Bogosort goes through the same motions regardless of what it's trying to sort, meaning every configuration is simultaneously the best, and worst case scenario
Also Bogosort could (theoretically) take infinite tries to finish if you get infinitely unlucky, and as we all know potentially infinite runtime is something everyone would want in an algorithm :P
Significantly, it's using independent tries. That means no matter how long it has run, it's no more likely to finish soon. For comparison, consider a bubbly bogosort: If the first shuffled item is in the correct place, lock it. Shuffle only the remaining list. Still may take infinite time, but has some chance of making progress (until it's down to a coin toss).
I like how Bubble sort often looks over at Stooge sort after they finish, and Stooge sort does the same to Bogo sort, as if they’re thinking, “Are they done yet?”
These people straight up animated a robot going back and forth 609 unique times, and everything else that goes with contextualizing the sort properly...
O look, I got the exact arrangement I wanted, except the last two balls changed places. What do I do? Quicksort: Change their places. Insertion sort: Take the last ball; put it where it belongs. Bogosort: 7:35
For those wondering: the probability of a given list of n items being sorted on a random shuffle is 1 in n!. As an example, the 6 item list had 6! = 720 combinations so the odds of a given shuffle being correct were 1 in 720. Thus, bogo had a slightly higher than 50% chance of being correct after 479 permutations. The formula for finding the odds of success after t trials given n items using bogo sort is (1 - 1/n!)^t. The average amount of excess comparisons would have been 3. So we have (3 * 479) + 5 comparisons for a slightly higher than 50% chance of success = 1442. The formula for the amount of comparisons for a probability p of success with n items using bogo sort is n/2 log_(1-1/n!) (p) + n - 1. This formula works generally: if you have a random chance C(n) of being correct on a given trial and need to check the list to see if you're correct, then the average amount of comparisons needed is given by n/2 log_(1-C(n)) (p) + n - 1.
THE RETURN Also, can you do gnome sort/optimized gnome sort and bad sort? I think of them as similar but it always seems that gnome sort is just more efficient and I don’t know why

@@paper2222 it's actually best case O(1), average case O(n!), and worst case O(infinity)
@@minetech4898 false. it still has to check if the pairs are sorted even if it is given an all sorted pair. so the best case is O(n-1).
@@imadhamaidithat's true, I never actually considered the isSorted to be part of the algorithm for some reason.
I like how the stooge sort bot is just looking around mindlessly while waiting for bogo sort to finish, but it's been established already that they have incredibly poor eyesight so he's not really seeing anything.
the only reason the channel's hiatus took so long is because they had to animate bogo sort lol
i feel bad for the guy who had to animate all that honestly
I'm sure that the animation is automated in some way

@@kajwbidonajdowlem5013 it is quite literally a video about *automated* sorting
Notes:
The expected number of comparisons that this bogo sort will make to sort 10 balls is 12,829,490,
Adding one more ball brings this number all the way to 152,369,679 !
Also:
The robot in this video got lucky, as on average six balls will take bogo sort 1734 comparisons!
and 720 trials

who asked
@debblez
for ten it will take on average 6,235,300 comparisons

This might be the first time I've seen a bogo sort actually succeed.
Statistically BOGO sort is guaranteed to succeed eventually
@@FoxDren given a large enough list (not too long, just a phone book or something) then it could, maybe, succed.
not in my lifetime tho
Technically speaking, BOGO sort has the smallest possible sort number.
... and the highest, whoo! rAnDOm¡
Yea, the first and last time lmao
Worst Case Scenario: If there are n items, then there will be n! (n factorial=1x2x3x4x...x(n-1)x n)
permutations until he finds the correct one! If there are 170 items, then he will have more than 1.80x10^308 permutations
36:51
Bogo actually looks at every ball here. I think it would be sufficient to swap just the last two, maybe three.
But no. Bogo must bogo on.
Sounds like an optimization, but I don't think it will make much of a difference on average.

David Morley How do you know?
I know you were skeptical about doing a video on Bogosort back when, but the visualization you came up with for it is honestly amazing, and the fact that you went to the trouble to animate over 30 minutes of footage of just Bogosort shuffling the sequence over and over again is doubly amazing. Perhaps you just feel like you caved to what the mob wanted, but honestly? I say bloody good show and if you ever did another one it could be literally anything and you'd have absolutely nothing to prove.
Also, fun fact - the probability of randomly getting a six-object sequence in its correct order at least once after randomizing the sequence 345 times is only around 38%. So for those who joke that Bogo is the fastest sort if it gets lucky, consider that what you see in this video is actually _pretty good_ by Bogosort standards. You need around 3,315 trials before you have a greater than 99% chance of the sorted sequence appearing at least once.
30 minutes of Bogo Sort to study/relax to.
OK I wanna make a video
Make more list: sleep, shower
honestly this 30 minute section is more fun (and uses way less stackoverflow questions) than actually coding up a better sorting animation.
I mean hey I fell asleep to this
@@antirogue825 He’s just standing there… MENACINGLY!
I'm loving the way stooge sort just looks around, politely trying not to stare at bogo sort as the minutes crawl by
I'd love it if stooge sort randomly started re-examining the sort it did. Considering how the algorithm works and all
My goodness. You actually rendered half an hour of Bogo Sort.
I can smell the smoke that come out from udiprod's pc
I hope they used something to automate the animation because I'm willing to bet at least 5 animators shot themselves before they even managed to convince someone to animate it.

Bogosort was my first introduction to why time complexity really matters. With a small number of elements, it doesn't matter if you use bubble sort or quick sort or whatever, but you try a bogosort on just 15 elements and you might as well just sort them yourself lol.

Or perhaps a disappointed sigh
I thought Bogosort was shaking its head each time it saw one out of order. Guess I was mistaken.
Quantum bogosort is a hypothetical sorting algorithm based on bogosort, created as an in-joke among computer scientists. The algorithm generates a random permutation of its input using a quantum source of entropy, checks if the list is sorted, and, if it is not, destroys the universe. Assuming that the many-worlds interpretation holds, the use of this algorithm will result in at least one surviving universe where the input was successfully sorted in O(n) time.
I was thinking "they wouldn't let bogo sort finish would they?" Then I saw the length of the video..
Genuinely surprised this wasn't an April Fool's special.
If there was an additional ball for bogo to sort this video would probably be 5 hours long
I wish more people would show algorithms like this. It makes so much more sense than bars moving around

Okay, so, A. This series has been incredibly I formative. Now I can enjoy those random recommendations of visualized sorts on a whole new level, since I actually know what some of them do.
B. You absolute *madlad,* you could not have driven the point more perfectly home with bogosort. I saw Stooge win, watched for maybe three more minutes, and then it *properly* dawned on me how the math worked out. And then I checked the video length, and burst out laughing. Absolutely amazing. Keep doing what you're doing, I'm gonna go watch the rest of your vids.

bogo actually won right after before stooge finished sorting
SPSheep that hurts my eyes, good man

His dad would have left the room, left the house for milk and then actually come back by the time he sorts the balls.
bogo is my favourite sorting algorithm. I'm convinced that whoever first thought of it chuckled at themselves.
26:10 has an easter egg.
:o
Thank you I guess
Wait... HOW DID YOU NOTICE
@@romeolz uh he watched the whole thing how else
Oh no
I think my favorite part of this is how Bubble just looks around awkwardly like it never expected to finish first
My favorite sort algorithm is one I call thermodynamic sort:
Background:
Physics show that the universe likely will reach a time where its energy is evenly distributed everywhere, and thus, nothing happens - time is frozen, forever. This is known as the heat death of the universe.
Algorithm:
1. Define some time span T
2. Wait for T time
3. Check if universe has reached its heat death. If so, you're finished. If not, return to step 2 (you can also return to step 1 and redefine T, the algorithm's correctness remains)
Proof:
By the time the algorithm halts, the universe has reached its heat death and no form of intelligent life exists. With no brains to think it, the concept of "comparison" ceases to exist and thus no element is less than a preceding one. The list is ordered.
However, there would also be no way for the algorithm to continue existing as no one could actually check if the heat death has occured, as if it did then there would be no minds to proccess that it occured.
if you just destroy your computer then there will be no more data
no data means an empty set, which is sorted
plus, given that destroying a computer does not take more/less time depending on list length this algorithm should take O(1) time.
@@englishmotherfucker1058 sorting files in a folder would delete the folder
😒
Ahh, finally, a timely sorting algorithm. This one operates in constant time!
This actually calmed me from the most traumatic event I've had thus far in 26 years of living. I honestly might start liking math now...
I feel like Stooge should have shut down halfway through Bogo's tomfoolery.
You need more likes
Lol
I saw a comment on an earlier video from about 5 years back about Bogo sort and I thought that I would never be able to see the glorious inefficiency of it rendered in an udiprod video.
I was wrong, and I'm so glad I was.
(Now I just want an endless live stream of miracle sort!!)
Bubble sort (10 balls): 36 comparisons
Stooge sort (10 balls): *_81 cOmPaRiSoNs_*
Stooge Sort (6 balls): 27 comparisons
Bogo Sort (6 balls): *_6 0 5 C O M P A R I S O N S_*
*9
OK I will copy
@@groszak1 Ah okay I didn't realise.
Now do same but 100 balls
That introduction part literally looks just like a freaky dream I had when I was a really young child, with the blue gradient background and the weirdly moving humanoid characters.
I am amazed how "comlicated" things like sorting algorithms can be explained in a way that even i child could understand them.
With the right person and the right methods you can explain anything to even the youngest of children.
@@Dougiewoof I'm not so sure anyone could by any method explain string theory to a baby.
@@Huntracony yeah I think the minimum requirement for being able to learn anything is a fully developed brain.
@@theteddychannel8529 not fully developed, since that doesn't happen until around age 25, but definitely partially developed
@@loreleihillard5078 I don't know man, maybe 25 IS the minimum, simply because I'm including all "normal" people (meaning without mental disabilities) which means very dumb people are part of the equation.
when i clicked on this video i was like " is this really gonna be a 40 minute video about bad sorting algorithms.
its just an elaborate troll of bogo sorting
I was really hoping bogo sort would get lucky and finish in less than 310 but oh well
*360, so he did get lucky i think
tbf as permutationso can repeat you should expect 720
@@derekliu793 yeah I somehow messed up the math lol because I knew the probability was 6! I just halved it wrong
A probability of 6? I thought that a probability was always a number between 0 and 1.
@@adrihooijer536 the probability is 1/6! (6x5x4x3x2x1), but a lot of time in probability you use cases as probability and in the other way (because probability is the inverse of the cases (when all the cases are equally possible and only 1 case wins))
I love how Bogo sort has two extreme cases.
- It randomizes the list once and is instantly correct.
- It literally takes an infinite number of attempts to be correct.
Mathematically, both of these are technically possible outcomes.
He's back. Probably did a bogo sort by hand...
Wait, She's a HE?
@@anawesomepet ??
@@anawesomepet I need to know.
with most other sorting algorithms, there is usually some way, some arrangement of items you can use to maximize swaps, such as giving Stooge Sort a list that's inverted. but Bogosort goes through the same motions regardless of what it's trying to sort, meaning every configuration is simultaneously the best, and worst case scenario
Also Bogosort could (theoretically) take infinite tries to finish if you get infinitely unlucky, and as we all know potentially infinite runtime is something everyone would want in an algorithm :P
Significantly, it's using independent tries. That means no matter how long it has run, it's no more likely to finish soon.
For comparison, consider a bubbly bogosort: If the first shuffled item is in the correct place, lock it. Shuffle only the remaining list. Still may take infinite time, but has some chance of making progress (until it's down to a coin toss).
I like how Bubble sort often looks over at Stooge sort after they finish, and Stooge sort does the same to Bogo sort, as if they’re thinking, “Are they done yet?”
The mad lads actually did Bogo sort 👌
3:20 LOL, I love bubble sort bot’s just like “wait, what? I finished first?”
These people straight up animated a robot going back and forth 609 unique times, and everything else that goes with contextualizing the sort properly...
There's something so funny about this, just realizing that the video is 40 minutes and its just this awkward robot trying its best
22:09 Definitely worth the wait for this part
26:05
O look, I got the exact arrangement I wanted, except the last two balls changed places. What do I do?
Quicksort: Change their places.
Insertion sort: Take the last ball; put it where it belongs.
Bogosort: 7:35
For those wondering: the probability of a given list of n items being sorted on a random shuffle is 1 in n!.
As an example, the 6 item list had 6! = 720 combinations so the odds of a given shuffle being correct were 1 in 720.
Thus, bogo had a slightly higher than 50% chance of being correct after 479 permutations.
The formula for finding the odds of success after t trials given n items using bogo sort is (1 - 1/n!)^t.
The average amount of excess comparisons would have been 3. So we have (3 * 479) + 5 comparisons for a slightly higher than 50% chance of success = 1442.
The formula for the amount of comparisons for a probability p of success with n items using bogo sort is n/2 log_(1-1/n!) (p) + n - 1.
This formula works generally: if you have a random chance C(n) of being correct on a given trial and need to check the list to see if you're correct, then the average amount of comparisons needed is given by n/2 log_(1-C(n)) (p) + n - 1.
isnt n! in math like n+n-1+n-2...n-(n-1) or does it go to n-n aka 0?
or is it multiply
@@Da_Rivulet nah n! = n*(n-1)*(n-2)*... until (n-x)=1
Bogo Sort is like if a sorting algorithm had a terrible gambling addiction.
Bogo sort actually reached 5 in order in only 30 or so comparisons, which is way better than the average 120
I'm glad they gave Bogosort a little hat, he deserves it. He's trying his best
This channel doesn't update that frequently, but I can assure you that every single episode is of top quality👍
This video is pure gold, thanks for letting bogo sort until the end
THE RETURN
Also, can you do gnome sort/optimized gnome sort and bad sort? I think of them as similar but it always seems that gnome sort is just more efficient and I don’t know why
What's bad sort?
It’s described on the Wikipedia page for bogosort, but I am having a hard time following its explanation.
Gnome Sort is basically Insertion Sort that went on a bender and is currently hung over
I half expected Bubble to get impatient and start helping.
Shoutout to the person who animated fucking 40minutes of a robot shuffling and checking bowling balls
Stooge sort is like an exaggerated version of a human looking up if the door was properly closed.
This channel is a gem, keep it alive!
37:07 the fact that it was literally one off from being correct and it just shuffles them all around again
Alright, that was great! See you all again in 2022 when udiprod uploads again!
he's taking another long hiatus to animate bogobogosort
Wow, apparently I was... half right
OMG you actually did the animation! I've been waiting 3 years to see that! You are the MVP udiprod !
Anyone else watching stooge sort do its thing at the start and being like “your doing great honey!”
I loved Bubble sort just standing there, awkwardly waiting for Stooge sort to finish and being unsure of what to do.
Me at night : Quick sort
Me at math test : Bogo sort
everyone's talking about bogo sort but man i feel bad for bubble sort
he was finally gonna win one but was left with confusion while waiting 2 minutes for stooge sort to finish and eventually win
you know videos about sorting algorithm is gonna be interesting if it exceeds 5-7 minutes
These are so addicting... I don’t even need to learn this but I appreciate forgetting about it for about a year and coming back to this new one!
i cant believe i just watched over 20 minutes of bogosort on my own volition
Stooge Sort looks like it's anxious and has to keep double checking what it just sorted.
I would very much like to see the cocktail shaker sort featured on one of these videos!
Would be cool if the Cocktail Shaker sort robot is dressed like a bartender as a nod to the name. What do you think @udiprod ?
i love how bubble sort just waits so patiently
FINALLY, the sorting algorithm we've all been waiting for!!!
"I must apologize for BOGO sort. He is an idiot. We have purposely trained him wrong, as a joke."
