[@user-yp4wt8yq9b]

algorithms are just a bunch of finite instructions to solve some problem, you actually know what they are and how they work since you might use them all of the time like the steps you follows to divide two numbers, the concept and use of algorithms is of a mathematical nature, when programers tells you that the reason why something works is because of algorithms it's like asking an engineer why doesn't the bridge fall and then he just tells you that it is because of math he is telling you the truth but not giving any actual insights which is the most important part for understanding algorithms since in order to create an algorithm you must first understand how to solve the problem and then give the instructions to the computer so that it follows them and solves the problem for you the reason why many programers can't explain what they are doing is because in order to use an algorithm you don't need to understand it you can divide 2 numbers whithout knowing what is division or what are numbers if you just follow the steps so there are some times when programers use other programers algorithms to make their own and they end up solving problems by just using a bunch of algorithms that they don't understand and neither the general instrctions since they can also copy them from somewhere else without getting any real insights

For the sleep sort one, what if we take the biggest element and scale all elements down by that number. Then, it would take atmost 1 second to sort. Though still it would leave the sorting to the CPU scheduler.

[@awiewahh]

Diffusion was not first developed at openai. Diffusion as we know it as an image generation technique started as the Denoising Diffusion Probabilistic Models (DDPM) paper that came out from UC Berkley with Ho et al in 2020. Dall-e 1 wasn't even diffusion, it wasn't until far later that openai joined the diffusion scene.

[@awiewahh]

@@en9717 My other comment seems to have been deleted, so I wont try to link the paper again. But the original image generating diffusion model has the arxiv code of arXiv:2006.11239 There have been previous diffusion models before that too, but not to the same extent as the DDPM paper. Regardless, none of them were through OpenAI.

My favorite algorithm is probably Perlin Noise. You touched on procedural generation in your wavefunction collapse portion, but the fact that the result is _deterministic_ (based on the initial seed) and independent of the order of the observations is just mind-blowning.

My favorite algorithms ATM are ones for video games. You see, video games are in the category of “real time simulation” meaning what you see is actually being computed live. That means that there really isn’t a bunch of resources to use; algorithms must be highly effective. The work of optimization is handled by trying to pre-compute things or fake things. My favorite example are oceans. The best water simulation (like in Sea of Thieves) is faked by pulling past data from real science buoys and essentially replaying real water (lol). Otherwise computing water in real time is terribly expensive. It’s a hack but an example of how a resource constrained environment produces creative solutions.

[@ric6611]

That's actually hilarious, so often nowadays we just forget the simplest solution.

I hope the field will make a huge leap once generative AI has been incorporated into NPC behavior, 3D texture generation, on-the-fly adjustments of the vibe/music/storyline/difficulty levels etc. Soon games could come out that may play out in ways totally unexpected to the developerts due to the increased degrees of freedom.

I was expecting something related to Signed Distance Fields... Graphics programming has some insanely ways of overcoming challenges

[@carljones9640]

Pedantry warning: SGD is an amazing optimization algorithm, but it is not correct to say that SGD is what propelled us into the current AI era - that would be backpropagation. If you want to assign credit to a single algorithm, it would be more appropriate to assign it to backprop, since backprop is what allows SGD to solve the credit assignment problem in the first place. Without backpropagation, a network cannot learn. Backprop is the algorithm that SGD relies on in neural networks to actually train them. So, it's not SGD but backprop that let us do AI. That being said, the real winner is raw compute power. Things like SGD and backprop have been around for 40+ years (backprop over 50) and were already used in AI as far back as the 1980's. The problem is that you couldn't handle anything with any meaningful depth until the mid-to-late 2000's because the compute power and memory just weren't there. The explosive advancement of AI really is just a matter of hardware advancement, especially anything that allows for parallel computing. Thank you, video games, for getting someone to invent discrete GPUs.

[@R2D21111W]

In the lecture 'Logic of living systems' that included Boids we also covered so called 'Core Wars'. Basically its about different assembler code fighting over memory via replication and 'killing' other code. Maybe you are also interested in this subject 😊

[@josephmalham725]

Just a footnote for anyone who sees it, real world wavefunction collapse isn’t dependent on looking at particles. The word observation is used but that’s a catch all term for some form of physical interaction with the particle. Human vision and perception doesn’t have the ability to magically cause collapse, but if we want to look at it, it has to first collapse.

Weird algorithms summary: Wave Function Collapse (0:43): Procedurally generates maps for video games by collapsing possibilities upon observation. Represents an initial map in superposition, selecting tiles based on consistent rules. Diffusion Algorithm (1:41): Derived from thermodynamics, reverses the process of spreading particles to generate coherent images. Used in image generators like DALL·E and Stable Diffusion, with potential for audio and video generation. Simulated Annealing (2:40): Optimization algorithm inspired by metallurgy, balances exploration and exploitation. Offers a metaphor for a developer's journey from exploring diverse technologies to specializing in one. Sleep Sort (3:40): Unconventional sorting algorithm that delegates sorting to the CPU scheduler through thread sleep times. Genius yet impractical, as it relies on the scheduler to execute the sorting process. Quantum BOGO Sort (4:19): Theoretical sorting algorithm leveraging quantum mechanics and multiverse theory. Hypothetically relies on observing parallel universes to find a pre-sorted array, requiring a portal gun. Shor's Algorithm (4:59): Quantum algorithm for integer factorization, potentially threatening RSA encryption. Leverages quantum concepts like qubits, superposition, and entanglement to perform parallel calculations. Marching Cubes Algorithm (0:00 & 6:10): 3D mesh generation algorithm used for rendering MRI data in 3D. Processes a 3D scalar field to create a mesh by considering neighboring points and predefined polygons. Practical Byzantine Fault Tolerance (PBFT) (6:48): Distributed consensus algorithm essential for maintaining network integrity in the face of node failures. Enables nodes to reach a consensus on executing changes despite up to one-third of nodes behaving unpredictably. Boyd's Artificial Life Program (7:46): Simulates flocking behavior of birds using three simple rules: avoid crowding, align with the average heading, and move towards the center of mass. Demonstrates emergent complexity and beauty arising from simple rules, reflecting natural phenomena. Boyer-Moore String Search Algorithm (8:17): Efficient string search algorithm that becomes faster with larger search strings. Scans text from right to left, utilizing pre-processed tables for skipping characters based on bad character rules and mismatch occurrences.

[@desmond-hawkins]

The input to the marching cubes algorithm is a *scalar* field, not a *scaler* field. A scalar field is just a set of numbers associated to points in space. Each scalar can be a vector, like if you knew the measurements of wind speed and direction at regular intervals within a 3D area you'd be dealing with scalar fields. If it's about 3D modeling the number could be 1 or 0 to represent the presence of an object, or a quantity representing its color or texture, etc. A scaler is something that scales (resizes) something.

This video is great! More weird algorithms videos in the future?

[@isodoubIet]

The figure at 6:22 is incorrect. A tensor is not a 3d matrix, it's a more general concept. A scalar is a type of tensor. A vector is a type of tensor. A matrix is a type of tensor. A 3d array is a type of tensor. Tensors are, very informally, objects with n indices that satisfy certain transformation rules.

[@Jang09]

You're confusing the definitions for math and computer science. They are all essentially arrays of numbers in programming and are just given the names scaler, vector and tensor because they are representations of those objects. In math, a matrix is a linear transformation, and a tensor is a multilinear map (given a basis). The "informal" definition you mentioned is the one usually given in physics and it's only for the components of a tensor (which is typically all you have to worry about since physics should be background independent) but not the object itself.

[@isodoubIet]

@@Jang09 No, I am not. First of all, there isn't really a "definition" of tensor specific for computer science, since the term was just lifted from math and physics without much thought and no further theory was developed, and secondly, even if there was, it would still be the case that a tensor has an arbitrary number of indices _because that is the practice where the term tensor is used_ e.g. in machine learning. If you really want to drop the transformation properties, go ahead, but it's pretty silly to come up with a synonym for array. What you cannot do is say it must be 3d, because nobody uses it that way and that's a definition used only by you. " it's only for the components of a tensor" That is incorrect. It is the definition of the object. A single component of a tensor is not a very useful object.

[@Jang09]

@isodoubIet The transformation law is for the components of a tensor the indices are labeling the components this is pretty standard in physics. The word tensor in computer science is used for multidimensional arrays.

[@isodoubIet]

@@Jang09 "The "informal" definition you mentioned is the one usually given in physics and it's only for the components of a tensor " Is what you said above. You said it's _only_ for the components and not for the whole object, which is definitively incorrect. The transformation laws obviously operate on the components, but that's not what you said, nor is it something relevant or useful to bring up. "The word tensor in computer science is used for multidimensional arrays." I literally just explained this. 1. The word tensor is not used productively, its just a cute word that people who don't understand what tensors are decided to use for multidimensional arrays 2. computer science already had multidimensional arrays and 3. "multidimensional" means with an arbitrary number of indices, not just 3, precisely as I stated. You're trying to be absurdly pedantic, which I can appreciate, but you're also failing miserably. Just stop.

[@Jang09]

@isodoubIet I'm literally just stating that the same word is used in different fields to mean different things 😅 so your first comment doesn't make sense since your trying to use the physics definition on a CS video. And yes the transformation law only refers to the components of the tensor as the tensor itself is invariant to a change of basis.

Cool upload! I've been working on a new digital image Steganography idea that doesn't rely on an algorithm, but leaves the target image untouched and applies a given co-ordinate reference to the target bytes for extraction in the correct sequence. So technically, I could extract a 300KB GIF image of a fishing boat from a 124KB Jpeg image of a wedding dress. So basically you could never extract the boat bytes without the coordinate sequence. Because the boat has not been algoritmically 'worked into' the target image (wedding dress). I'm pretty excited about my findings...

Immediately my favorite 2 algorithms of all time, I'm definitely watching through this video.

[@corster8221]

I was hoping you would cover bloom filters

Came to watch as soon as I got the notification!

Early fireship vids hit different

[@mcmoneyleswag]

A fireship video that doesn't fill me with existential dread? I'm still full of it, but liking the change of mood.

I remember how Wave Function Collapse was theme of my first course work i ever made. It's so much easier to understend then other generative algorithms

When I realized sleep sort actually sorts it blew my mind. It might not be fast but at least it runs the same speed on an old computer vs a new one.

[@faithcyril513]

i love this channel so much!!! True definition of edutainment

[@LiquidSpider]

sleep sort has to be the funniest algorithm i've ever seen

That bird flocking 3 rules system, I heard it was 3 different rules: 1. Flock together 2. Keep equidistant apart 3. Avoid predators. This last one is what creates the spectacular patterns we see when a large crowd looks almost like smoke from a distance.

I actually DID wake up with that thought once, I had a 2D MRI scan of my skull and I needed to visualize it in 3D. Despite the technology already existing I was pretty young and I didn’t know. I managed to get it to work on myself.

You are really good at computer science not only creating website you understand deeply inside of computer science

[@-uz]

Id love another video like this !😊

[@b3rgundy]

That was some spicy interesting content, bravo!

I remember making a Boids project, I even uploaded a video. It consisted of rendering a bunch of mouse cursors to the screen where they would fly around your monitor and avoid the "real" mouse Made for a good background
