This project was inspired by: Jeffery Ventrella's Clusters www.ventrella.com/Clusters/ I don't have access to Ventrella's code but I guess the main difference of my project with the other particle life projects is that I didn't implement collision detection and this has simplified the simulation. Also, I added GUI controls to change the parameters in real-time. This allows easy fine-tuning & exploration, hence, I was able to find some never-seen-before patterns emerge form some extremely simple models of relations.
The code here is probably an order of magnitude simpler than any other Artificial Life codes out there because I started this solely as an educational material for non-programmers and the general audience.

If you came up with this you’re a genius. Even if you got inspiration from other projects making something with that little code that can simulate these complex emergent properties is a huge achievement

@brainxyz Год назад

Thanks for the compliment. This project was inspired by Ventrella's Clusters (the link is in the descriptions). Once I wrote the code, I spent the entire month trying to make the code as concise as possible and as educational as possible. Hopefully, this presentation inspires more work on investigating emergent patterns from very simple rules.

@@estebanod the point is, the game of life shows very well, just like this demonstation that we see above, that a set of very simple rules can produce very complex and unpredictable behaviours(just like in real life)

@RavenMobile Год назад

@@Mushele This is far closer to representing emergent life coming from simple rules than Conway's Game Of Life. I absolutely love Game Of Life, but this looks like what one sees from microscopes. Cells consuming other cells, cells losing their cell wall and leaking their insides, cells that are highly active, other cells that are mostly stagnant, etc.

@joshmyer9 Год назад

I wonder how much more emerges if we make the rule coefficients a function of a common parameter (we can call it "temperature"), then have that variable go through a "day cycle" of sin(t). This might make some of the very unstable/twitchy patterns more stable for a bit, and vice-versa. Or make t itself a function of (x,y) and make warm/cool pockets with different stable patterns, swapping particles between them. Lots of neat stuff to play with here, thanks for sharing it!

@WomboBraker Год назад

Thats a cool idea

@giannipiccioni8411 Год назад

@AlissonNunes Год назад

Isn't "temperature" the "value" of how much particles moves? At a certain point, some measurements that we use at normal level doesn't apply to molecular level

@AlissonNunes Год назад

The "temperature" increases by the sun that emits radiation (photons), which are more molecules... Or I'm just being dumb

@joshmyer9 Год назад

@@AlissonNunes Not dumb, but I do think you're taking the model a little too literally (which his presentation kind of encouraged). This model is too simple to capture anything like that level of detail. It gives us big picture, super hand-wave-y patterns, which is neat, and helps guide one's thinking for more fine-grained problems. This is why I said "call it" temperature: it's a kinda-sorta analogue for temperature within the very coarse-grained model we're using. Honestly, my motivation is entirely to make it fun to watch for longer. It's a bummer that each model stabilizes to a static state, though. I'm mostly interested in finding ways to make it visually interesting for longer spans of time =)

@NorthernHurricane7 Год назад

While Conway's Game of Life has been impressive for a long time, the striking part of this adaptation is the organic way the movement, shapes, and patterns appear. There are a number of ways to use this approach to visualize concepts about chaos, probability, prediction, and determinism in systems. The first-principles development approach to set it apart from similar programs is the cherry on top. It looks great!

Computers and code are the most accessible facsimile to a generic laboratory. Be it some finance stuff, physics, biology, quantum mechanics - whatever - if you take an interest and want to see how an idea pans out, coding is the way to go. Frankly, it even teaches respect to all those scientists before the computer age, who managed to produce useful insights without computers :) But today, anyone should be able to code a little, so they can use it as a tool of learning.

Amazing work! It'd be a million times better if combine this with evolution-like process. What I can think of: 1. Add a new type of object, let's call it "nucleus" 2. Genetic information: Each nucleus stores the information of formation of particles in polar coordinates to it. e.g. red: [ [1, 90], [2, 45] ], blue: [ [2, 60] ] Each will be spawned surrounded by other particles arranged according to the gene. 3. Metabolism: Each time there's another type particle that is close enough to a nucleus, it will "eat" it and increment a counter of that particle inside it. e.g. red++. 4. Reproduction: When there's enough particles eaten to satisfy the number of particles of each type needed for the genetic code e.g. red == 2, blue == 1, another one of this nucleus will be spawned elsewhere 5. Mutation: For each reproduction process, there's a chance of a small change in the genetic code. 6. Death: Each time a particle that a nucleus "owns" is eaten or gone too far, the HP of that nucleus is reduced. If it's 0, the nucleus dies. 7. Growth: The genetic information can be split into stages and the nucleus will need to consume enough particles to go to its next stage. It means the consumed particles will be respawned around the nucleus based on the next stage's gene. Reproduction will be done after the last stage is reached.

Some of the instabilities could be a result of simulating in discrete domain. Different sample time: if you multiply all the forces by 0.5, record the simulation and play it at 2x speed, the results with fast moving particles (e.g. instabilities) will be different. There are also continues domain solvers, but understandably that would make it not very approachable.

@@mccvargues7792 I think yes but I think you said the opposite. he's using 1/d instead of 1/d^2 if he excluded the sqrt d would become d^2 and 1/d^2 would make the interaction between particles get weaker as distance increases than 1/d. So yes the behavior would change. But you'd be using the correct formula for gravity as he mentioned for less effort. And the interaction has become weaker for greater distances.

@zbnmth Год назад

Kuwertzel, Unity is a "fourth" level programming language. Physical logic gates -> Machine language -> Programming languages (C, Fortran, etc) -> Fourth level languages (Unity, Mathematica, etc).. That is to say, Unity has something like C between it and the machine code. Generally, the more user-friendliness you have, the less efficient the physical machine (CPU) is given instructions. Maybe you already knew, but it's why your program will run (very) slow when coded in Unity.

@dealloc Год назад

@@zbnmth This is just plain wrong. I've written Particle Life in JS (fnky/particle-life on GitHub) and its performance is fine. This is without much optimisations (no WebGL shaders, just Canvas and purely running on the CPU). Unity is first of all, not a programming language, but an engine. Secondly, any language can be slow if you don't know about pitfalls that are usually general to every language; i.e. allocating within a deeply nested loop can be very slow if not cached or managed properly. Doesn't matter whether you write Rust, C++, C or even Assembly. The important part is to understand those pitfalls and how to use the language to avoid them. C#'s runtime (CLR) is fast and is used in many applications, more complex than this. Not only that but your C# code is also heavily optimized through Roslyn before being translated into MSIL/CIL and then to machine code by the JIT compiler.

@OscarLazzarino Год назад

Uh, no, looking closer at the code now I see that rule() only updates atoms in the first group. So you can have asymmetrical forces which is really "non newtonian" but is probably what allows the emerging patterns. Very cool.

Nice observation! but I don't think so because these rules specify uni-directional relationships

@brainxyz Год назад

@@OscarLazzarino Yes to make it symmetric f1 should be equal to f2. Asymmetrical forces don't exist at the atomic level but I guess it is abundant at the level of large compounds, proteins, and enzymes

@user-rr7uh4wm5y Год назад

@@brainxyz all forces are symmetrical in real life according to Neuton's 3rd law. But this asymmetry might be why your simulation makes such interesting results, so imo it is a good thing.

@user-rr7uh4wm5y Год назад

@@brainxyz also there is no conservation of energy because of the asymetry. But again, I think it is cooler

Thanks so much for sharing this! Hours of fun making up relationships or just hitting randomise (the code-along was fun too!)

Brilliant. I was searching for life simulations and found your video which goes very quickly from a simple dance between two yellow dots to the whole mega freakin universe thing with all its complexity. Well done! Now, me go programming. . . .

Really great work! It would be amazing to put this into Unity 3D and also add the third dimension along with some smooth random camera interpolations to view everything.

It would be interesting to see what happens with a more sophisticated integration algorithm, such as Runge-Kutta for the force-acceleration-velocity-position.

smoother but slower motion

@FreeScience Год назад

@@anywallsocket Sure, but I'm more I'm thinking things like preservation of momentum and energy.

@anywallsocket Год назад

@@FreeScience the dynamics will evolve differently, but only slowly as a divergence. The chaotic nature of the system will quickly override any predictability anyway.

His integration scheme is broken. He is isn’t accumulating forces and stepping, he is collecting forces and stepping at the same time.

love it, i actually wantef to do something Similar a few months ago, but never got to it and then forgot about it, thank you for making this video

You came up with beautiful, intellectual, and extremely unique. You have earned many people's subs including mine. I hope you get the level of recognition you deserve.
