Evolution Simulator of Creatures Doing MATH (Part 1)

Yoy, math is everybody's favorite subject
The camera gets super shaky at certain parts of the video. I thought I stabilized it, but I guess it didn't work.
If you're watching this before the edits take effect, then you'll see 8 minutes of black silence at the end of the video. Don't watch those 8 minutes because you will gain nothing from that.

[@THATcommentor]

I came to this video thinking that these creates were actually going to evolve solving more advanced math problems... I was wrong

[@jpress1e]

You aren't alone.

[@-yttrium-1187]

Well, they sort of are. In this case the best solution was twitching however in the next video we might see more tactics.

[@cheydinal5401]

Me too, that title is kinda confusing. But to be honest a (kind of) neural network is much more amazing, I don't get why carykh didn't put that in the title

[@-yttrium-1187]

Cheydinal Because its not a neural network at all. Neural networks dont directly add and subtract values and connect to other 'nodes' trough variable strengts. Its better (and simpler ) to use very basic functions like positive and negative numbers with operators. I guess he wanted 'Creatures doing MATH' in the title instead of 'Creatures evolving to learn cause and effect of different operators and numbers to their survival'

[@cheydinal5401]

I think it would be interesting to add something like "Muscle fatigue" where muscles used too many times a second start "wearing out" meaning their min and max values come closer together the more they are called per second producing less violent vibrations.

From my experience with making simulations involving evolution, genetic algorithms love to take advantage of small errors and technicalities in the rules.

[@pairot01]

Isn't life itself an abuse on the technicallities of the laws of our Universe?

[@KnakuanaRka]

Joaquin Pirotto What do you mean by that?

[@pairot01]

I mean that the laws of nature aren't there to support life or to make it happen, life is an accidental consequence of them and their technicalities. DNA is just one of a near infinite number of chemical compounds, life sustains itself on water, but there's plenty of other compounds that are deadly to every form of life. Most things are not what makes life possible, it's just a very very very very tiny minority and special cases of the rules and building blocks of the Universe that make life possible.

[@caffeinatedspider3224]

Quiet, before the devs get out the ban hammer and patch out the "life expliot" in the next update.

[@CreativeVery]

I know this project is probably out of your interests, but I have a proposed way of getting creatures that don't twitch: Add "energy". Every time a creature contracts and extends a muscle in one full cycle, it will loose a bit of energy. When a creature runs out of energy, it stops, exhausted. This is obviously just a more "sophisticated" way of explaining a limited number of contraction-extension cycles.

[@KnakuanaRka]

Doctor Cereal Yeah, that would be a better way to stop twitching than simply turning the multiply-self-by-negatives (the ones that caused the twitching) to constants, which destroys a lot of useful stuff. I suggested in part 2’s comments that if he wanted to stick to time limits, he should just throw out such creatures and reroll them.

[@LoongYawLee73]

Vroom, vroom, the creatures looked like motorcycles.

[@potionoffireresistance9901]

[@martinshoosterman]

Cheydinal Rotational muscle. Not rational muscle. Please read more carefully.

[@Ian07_]

You should make it so that if a creature has more than 9 muscles or nodes, the species name uses hexadecimal. S60 (6 nodes, 10 muscles) -> S6A S72 (7 nodes, 12 muscles) -> S7C S73 (7 nodes, 13 muscles) -> S7D S74 (7 nodes, 14 muscles) -> S7E

[@MVBit]

But what if a creature has 16 or more?

[@Rastafa469]

well at least not after 4 billion years of evolution

[@Kerrmunism]

Troncoso are you saying that with every comment?

[@253198253198]

I don't know if it would actually help, but I think the simulator might be more realistic if it ranked creatures by absolute distance from the starting point rather than the distance to the right, as you could easily mirror any creature that moved left to get the equivalent creature which moved to the right. In this way, the creatures that move very far to the left can contribute to the overall progress of the entire simulation (mirror the left-moving creatures to get right-moving creatures). The only problem I can think of is that the x-coordinate would be opposite on the node and, therefor, might change the creatures behavior as it moves to the right (when mirrored). However, I think it could easily be fixed by changing x-coordinate to absolute horizontal distance from the starting point. Like I said, I don't know if this could help at all, but I thought I would mention it anyway. Also, I really enjoy watching these simulation videos, hope you can make more soon!

[@xavierevans6931]

[@brad1ey50]

Idea: Make it so that creatures can’t survive when there’s mainly just one type of creature. This will increase creature diversity therefore causing more interesting mutations to become more likely to happen.

[@dazzlealec3592]

"Click here to watch part 2!"*cries*

[@ben_yeates]

@Carykh if the fitness of the creature is calculated not by distance, but by efficiency (distance travelled / number of movements) the end result should be less "smasmy".

[@ben_yeates]

err spasmy rather

[@Wizarth]

I agree. Think of it as "energy expended". Although it can't really be "number of movements" per se, but perhaps total of absolute value of applied changes. I.E. +0.1 this frame, -0.1 (measured as a change of +0.1) the next frame, etc. Edit: It might also be useful to have a cost attached to changing direction. Also, possibly rather than having the axions control the muscle length, they control its delta (change in length). Could still easily end up with twitching though.

[@FyJonas]

+Peter “Wizarth” Newman he could just use force * distance to actually get the energy for every movement. This could be pretty costly though

[@Wizarth]

FyJonas Yup, sure could. Would definitely need the cost for this to have some multiplier though. Maybe even one that starts low and increases over time, to cause an annealing effect. Or one that's periodic, over generations (say, 50), to help mix things up and break stasis/plateau's.

[@phlimy]

+1

[@Thot-Slayer-420]

A couple of theories. A.) The increasing amount of muscles provides more output devices for the creature, increasing number of possibilities and potentially more capable creatures. B.) Increasing the number of nodes increases the number of constants, operators and sensors (py, px and time) which could lead to more complex axiom networks which could lead to more cabable creatures.

[@austinp6177]

Can you do a video showing creatures evolving to be as tall as possible? What is height: the highest point of the highest node after two seconds have happened, (to encourage stability) and when there is at least two nodes touching the ground. (to discourage jumping and spasms) You can make any changes to this that you want, I'd just like to see this happen. It would be very interesting to see. Thank you

[@Ussurin]

I actually find this video more confusing than orginal one. I've perfectly new why creatures moved in first experiment, but here I have no idea why you added math problems to nodes.

[@ProxyStarkilla]

I agree, the internal clock was simple but I have no idea what the math problems do or how they work or how it evolves. this one is way more confusing.

[@KnakuanaRka]

Ussurin I agree, this is more complicated. Add to that, if the restriction on their movement was changed from time to energy (used when muscles contract), the old creatures would way outperform these spazzouts.

[@logicbuilder1204]

The problem with the internal clock, is it was impossible to create sensors and use outside information, let alone process it. With math though, it allows for very complex processing, with very little nodes.

[@sallerc]

I like the format, keep up the great work!

[@brennenrudd3642]

the adding of the new nodes was certainly a good decision. Greatly expands the potential sophistication of creatures.

[@MartinDxt]

Yay you implemented neurons Hyped a ton on this

[@sebbes333]

@carykh Could you make it so when a creature has moved in the wrong direction (for 15 seconds) you switch it around (left nodes on right side and opposite) and give it another chance, because it has proven that it can move, but it got a unfortunate spawn which is unfair.

[@iancraftsandmines6266]

[@webx135]

The vibration makes perfect sense to me. Imagine sitting in a wagon and holding a stick. You can push yourself forward with the stick by pushing it into the ground. Then you can pull it back along the ground, before pushing again. It takes minimal effort. If your range of motion is limited, the best way to speed things up is to repeat this process at a faster speed. You could also see the "Nano HEXBUG" with a simple google search. It demonstrates this concept very well.

[@brokenbutler]

[@WildlyStapled]

I like the format. Also it's also hilarious of you to say you were going to make things simplified, and then go on to spend considerably more time explaining the "simpler" system.

[@BlarghMeow]

If you really pay attention, the twitching creatures actually act like an engine. One of the nodes acts like a crank shaft and the others act like the combustion chambers with the muscles being a piston. All the nodes alternate pushing and pulling, and since they are pushing and pulling so fast the crankshaft node goes back and forth, the more in sync the pistons are the more efficiently the crankshaft node goes back and forth making the creature move forward.

[@adamwright9678]

I love the concept and would love to see if it has been further developed!

You should try the Evolution Simulator with 500 groups of two creatures where one is on the left and the other on the right and which ever one moves more in the direction that is towards their opponment survives and the other one dies, basically Evolution Simulator with Wrestling.

“Lets simplify things” begins the most complicated description I’ve ever heard that was so much more complicated then the internal clock description

[@austinthomas6536]

The twitching you described is a byproduct of allowing muscles and nodes to pass thru one another as if they were freaking ghosts. You will begin to see more elegant movement if the structures of the creatures occupy physical space. Arcing motion, which i imagine as elegant, emerges when nodes bump. Otherwise the shortest path will always be in the same dimension.

[@austinthomas6536]

Yikes, this relates more to your other evolutionary algors, especially your vid w hurdles. But all the same, love these. Reminds me of my intro into collegiate comp sci.

[@paulomartins5071]

I think it relates to an engines piston. That twitching motion regulated by the synapses and all parameters in very high yet perfectly controlled frequencies is what drives our engines that drive our wheels. They kind of look like sliding cars ^^

[@fuchsfalke5063]

nice new idea with the axons :) i would recomend to add energy consumption for the creatures either a fix value or as food after every meter like in "Hill climb" - for every cm of muscle movement they waste a given amount of their energy that will hopefully teach them to move effective instead of much ...

[@IT-kone]

8:22 You do understand, that those twitching things resemble a lot like human myokines, which make muscles contract? Twitching is an integral part of moving around. It's just invisible to the eye.

[@teenagedgaming]

The message at the end actually scared me because i was in bed about to fall asleep and suddenly there was cary talking to me about pistons.

[@Thot-Slayer-420]

I consider the twitching exploit to be the equivalence to running. Thinking about it, the creatures use the 1,-1 alternating to quickly alternate the lengths to bring its foot (node) up and push it against the ground. It's similar to ther internal clocks that Cary implimented before, only at a much faster rate. Instead of a rate of 2 cycles per second it's 30 cycles per second.

[@happygarlic13]

you've really gotten good fast at making these videos! hoping my last comments were useful, looking forward to mor detailed comments of mine and the 2nd video of course!

[@memark8]

Wow, I have no idea how this works, but it's a genius way to give an incentive to create larger creatures. Seriously, all of my other suggestions are basically useless now! One thing I would like to ask is if we could please have the link to this version to play around with on our own. Thanks for the incredible content!

[@TheRealToaster2]

In this case, twitching is the most effective way to move across a surface. The problem is that, for more complex structures to form, the early forms of those structures must present some use to keep the creature to survive. But because distance is the only way to survive, they can only evolve with what simple mechanics they start out with. In real life there are many things that go into survival, and so multiple different things are needed for the creature to survive, so it develops multiple different parts for each task, and only in that scenario will more complex structures arise. Some structures can mutate to also help with other tasks. The whole point is that for complex structures to arise, they must be evolved from other structures that had/has a different purpose(s). There are two things you could that will potentially fix the problem you are having: either make it so that there are multiple roles for these creatures to accomplish (distance is not the only factor), or add some sort of sense to them (make it so that they can react to different conditions like their orientation, position, or whether or not a node is touching the ground). But mainly having multiple roles will work. Keep in mind that, before creatures could walk, they swam.

[@1r587]

[@NareshkumarRao]

Hi @carykh, I was thinking about how to get rid of vibrations, and maybe you can implement a sort of "energy" system, where the more intense the contraction of the muscle, the more "tired" it gets, hence a slower movement. This could be a way to get those nice graceful movements.

[@clul100]

I think a feature where a creature is shown stretched out, would really help when trying to understand them, since now they are much more complex

[@otomarrudolph651]

I love these videos so much

[@cody8111]

Twitching to move would take slot of energy. If we just twitched our ankles really really fast, we might move forward at a decent pace, but it would take waaaay more energy. Maybe give each animal a set amount of "energy" that was decreased by the difference in distance of a muscle growing + a constant. It would give a benefit to having long, planned strides.

[@w0ttheh3ll]

now we're talking! this is way better than the previous creatures.

[@markoftheland3115]

if you dont like spasmy creatures, one thing you could do is switching the muscles for bones, and what makes them move is a motor in the nodes, that can have a positive or negative value (clock-wise and anti clock-wise). You could make so the motors have limited rotation (for example we cant rotate our feet 360°, lol) so that the creatures dont evolute to just wheels. Also make the bones have variable lengths (just like our leg-foot system).

[@koibubbles3302]

When you realize that when the evolution was based off of contraction of nodes you get more animalistic forms of movement but when you put in math they start shuffling along the ground, almost like.. Cars?

[@AKIPOPOPOPOOON]

I like that here the populations of the various species change a lot, and there is no dominant species that stays dominant for more than a few generations, unlike the previous sims, with s33 or s45 taking the lead forever

[@LucasBurggraf]

i thibk it would be a great video, if you'd talk about the code for your programming;) great video though!:D

[@KohuGaly]

carykh, there is a very simple way to discourage creatures from twitchy movement. As you mentioned, twitching happens, because muscles receive alternating signals with Nyquist frequency, making them twitch between 0.5 and 1,5 length every frame. Firt thing that came to my mind is to add a simple low-pass filter to each muscles input. For example: Y[0]= X[0]*0.01+Y[1]*0.99 // Y[1] is previous output value from the filter, so the code would look like: y=x*0.01+y*0.99 With this filter in, the amplitude of fast-alternating signal will be reduced significantly, while slower changing/longer sustaining signals will be encouraged.

[@PeriOfTheGee]

proposition: penatly for complexivity. like 0.1m for every axon (this neuron thingy) so they would deevolve useless neurons so this would be clear to see whats going on inside of them.
