What is the iteration algorithm?

What algorithm is applied to the left image to generate the images on the right?

bumping for help please.

Can you make reverse iteration algorithm that forms the first image from the 3rd one?

majora masking algorithm

Unless you knew the agorithm to begin with then you are not able to put the image back together,
Almost like encyrypting something.

exactly like encoding something

probably not, there's a good chance you lose data in the process

not necessarily, not every algorithm is reversible. For example if the algorithm was "color every line with its average color". Another example would simply be hashing

not if the algorithm loses information. for example gaussian blur is irreversible

and if the algorithm destroys data you'r buttfucked

Rain of fucking algorithm

permute columns and stretch them?

Hmm , You've got a point,
But wouldn't a 'algorithm' be something that provides steps torwards a goal, therfor retracing the steps would work if you knew the algorithm.

my algorithm is crushing your balls, what's the retracing?

>Painkillers to remove the pain therfor retracing the steps of being without pain.

Accidental greentext ;^(

The classic explanation of an algorithm is that it's like a recipe. So if we make a cake, can we do anything to get the chocolate and eggs back.

Take modulo as another example.

Generally, a function can't be reversible unless it's injective (one-to-one).

Good way to put it user, Thankyou.

That looks like the room where you become a Deku in Majora's Mask

it is
you can pretty clearly see;
- link, and his shield (on the deku plant)
- majora's mask (under the right torch)
- tatl and tael (floating above the right torch)

it's probably sorting the pixels of each column

I'd imagine that they should be surjective as well.

Guess my algebra classes were good for something

You can just shrink the codomain to make it surjective.

True, but sometimes you don't know the range well enough to shrink down to it.

Give me an example.

I agree, some kind of sorting algorithm working on the pixels vertically. My first guess is merge sort, or some other algorithm that works on progressively larger chunks of data.

JUST

thanks doc
