I love the Radix sort algorithm. I somehow came up with it on my own when I was only starting to learn how to code, and I felt like a genius until I discovered that it was already invented 70+ years before I was even born.
While the elements aren't compared to each other, they (more specifically their digits) are compared to a constant to determine which bucket they should be in, so LSD sort isn't totally non-comparison.
@adiaphoros6842 that's a really pedantic way to view the term and removes the useful info we get when we use agreed upon terms like comparison or non comparison algorithms
I love the details in the machines designed to mimic the sorting behavior, like how the sorting head has wheels to shift the blocks, or the rails of the decimal radix sort.
Oh wow Radix sort is so much simpler than I thought it was Didn't really consider looking into it that much; all I knew about it was that it was non comparing
this is how postal services sort mail into exact delivery order, but instead of 10 bins to divide with, it’s more or less 200 bins that machines use to physically separate letters which allows the mail to be sorted in just two passes, saving time (i’ve worked with sorting letters like this for a few years, and i’m glad i finally found a video that explains what’s actually going on so i don’t have to anymore. sharing knowledge is fun, but this one is such a mouthful)
This channel is probably the only one I've been just as excited to see a new video of as a Computer Science student as I was when I was 13. Love how you explain things!
I've genuinely never understood radix sort until right now. You've made it completely intuitive. I thought the magic of radix sorting was in choosing what radix to use, but now I see that the radix is actually just the base of the numbers you're using, not an arbitrary number that you can select to get a different level of performance.
as a fun tip, a base-10 or base-26 (alphabetical) radix sort is pretty easy to do by hand, so if you ever need to sort a stack of papers it's pretty easy to just radix them up. usually i do an MSD radix and then insertion sort each "bucket" before combining everything together, but an LSD sort might also work
I imagine for alphabetical it's going to be difficult using LSD, say you're sorting "alphabetize" and "dog". If you don't manage to put the correct amount of "trailing zeroes" on "dog" to make it "dog00000000" so it's the same length, lsd will just make a mess. A computer can do so easily, but a human might have some trouble. For numbers though, as long as you know the max length to start with, LSD might be best.
This is a wonderful explanation! I was already familiar with this sort, but never fully understood how it led to a successful sort. The 'stable' property you described made it really clear!
Wow, this is the first time I've read or listened to an explanation of radix sort, but it's so simple and intuitive. I assumed it would be more complicated, like quicksort.
This is an incredibly good video. I've seen several videos to try understanding radix sort and none of them made sense. This video makes perfect sense and is easy to follow.
Glad to see this channel is still making great videos! You are GREAT and at making visualizations that are helpful. That radix sorting machine took a long time to animate I bet, worth it though.
Finally! LSD and MSD Radix! Fun fact: both Radix sorts are in base 2 except at the end, where random 4-digit decimal (base-10) numbers are sorted in, well, base-10.
Hi! I like watching your vids of visualizing sorting algorithms,you actually halped making me understand heap sort and stooge sort! Keep on the good work!
Back in the 60's I worked with pre-computer punch card systems. The LSD Radix Sort is the precise algorithm we used to sort stacks of punch cards on any desired field (a field being a contiguous set of columns on the card containing some number that we needed to sort on). Watching the animation brought back memories of those times.
I'm a big fan of radix sort, but I prefer bucket sort, which is quite similar. Bucket sort takes significantly more memory, but is several times faster because you can sort by multiple binary digits at once. I've found that doing a 4-bit bucket sort is a comfortable medium between memory usage and speed.
I love radix sort. It's conceptually so simple, it seems like it shouldn't even work, and requires very few comparisons to make an effective sort. But its simplicity and efficiency comes with a different cost; it's trading time for space. You need additional address space to store the partially sorted list. In systems that have plenty of memory, radix sort is a great choice. In systems with very limited capacity, however, radix sort may be impossible or significantly slower than in-place alternatives, especially when stability isn't relevant.
Thanks for this video =] I had never looked into or understood radix sort before now ^^ Any chance we could see a radix robot compete against the others? Perhaps with colored balls with 1 or 2 bits each for red, green, and blue?
Radix is linear unlike most other sorting algorithms. This means that as the number of elements grows, radix gets better and better. For small numbers of elements it's extremely inefficient because of its massive overhead, so it gets beaten easily.
Thanks for the breakdown! A bit off-topic, but I wanted to ask: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?
The fact that they've been using the same graphics for these videos for 15 YEARS is impressive

Welcome to computer science!
well hey just cuz someone else came up with it first doesnt mean ur not super smart for also coming up with it in isolation . . . !
you are still a genius by anybody's standard
i've gone through thinking i've invented a new sort TOO MANY TIMES.. i feel you bro
me too! for me it was bubble sort, i called it compare sort because it compared two numbers. I thought I was a genius
non-comparison based sorting algs stay winning, this has been one of the most satisfying visualizations I've seen

@adiaphoros6842 that's a really pedantic way to view the term and removes the useful info we get when we use agreed upon terms like comparison or non comparison algorithms
If we compare nothing we have no way of knowing if anything is sorted. Pretty fair to say this is as close as we can get

punch card sorters work this way. it has twelve pockets, for the twelve hole positions per column, plus a pocket for errors. very cool!

The block sounds are very satisfying.
We have never been so back sorting bros

Ho boy this gives me some wild college nostalgia and whiplash seeing a new upload like this.
Watching your videos is always a treat (regardless of one knows the concept or not!) 🙂

Restacking the sort piles is horrendous.
Requires double the storage of the original list.
