[@adityakhanna113]

Well, he supposes the predator comes from the left. So, the creature was stupid and ran right onto the breakfast table.

[@squiddler7731]

Yeah, I know, but I feel like a creature that blazes directly towards a predator still has a slightly better chance of surviving than all the ones that practically can't move at all.

[@adityakhanna113]

Dequan Milete Because it scares it? Well, i too agree that stationary creatures should be deleted. But that'd require a lot of tweaking?

[@squiddler7731]

Yeah, or it might slip by before a predator could react. And I imagine it would be easy to change it were creatures that don't go anyway are more likely to die out than creatures that go backwards.

Ik this comment is 7 years old but I feel like it may have been better to have the elimination gradient concentrated at distances closer to the starting point of 0 rather than the distances closest to the left

[@mirillis6083]

​@@gringusgamingor maybe change the code so that it always returns the absolute value so |-x|=x and then that is faster than something that doesn't move at all

[@anonymoususer9837]

That creature of generation 1 that went 7 meters in the wrong direction would have changed things a lot if it went in the right direction.

[@anonymoususer9837]

Would it be possible to override that one creature so it's mirrored, then see what happens?

[@jesusthroughmary]

Seriously. 100 generations later, no creature had gone 7 meters in either direction.

[@TheSuperskidz]

[@envy2682]

[@ascii_9727]

ah dude that -6m first creature was awesome with that wheel type of movement mechanism :( what a waste

[@lachlanmann4511]

Having the bottom 10% flip instead of die could really help maintain the diversity at the beginning

[@cryptexify]

Or just make the fitness dependent on the absolute displacement rather than the displacement to the right.

[@TheKdcool]

But that sort of prove how natural selection is non forgiving. Their goal is to get to the right so left is death haha

[@jasonh6312]

You wouldn't want lefties mating with righties, that wouldn't give you forward progress. However, what he should do is take any creature that goes negative and mirror its nodes so it goes positive. Seems like an obvious enhancement to me.

[@cryptexify]

True, but do they actually mate to reproduce? Or do they do it asexually? If it's asexual, then it doesn't matter.

[@ParallaxScene]

I think you should add a node that can detect contact with the ground. Have it output 0/1 this should allow for some contact based movement.

[@EleanorDrapeaux]

That'd be sweet

[@TomatoFriesLAN]

Feed that number into a rigid muscle. Now you have twitching.

[@ParallaxScene]

Tomatofries LAN You're kind of right you could delay the state change a few frames to account for that.

[@ZardoDhieldor]

One could implement a delay or let the node detect contact even if the distance to the ground is small but not zero.

[@revimfadli4666]

Or touching the ground means the output value increases over time, and vice versa

[@matthewfanous8468]

+Jacob Riley lol, this is like a half joke

[@CloudeAytr]

Or he could just change it so it's sorted by overall displacement and killed off accordingly and not just displacement to the right. Potentially ending in multiple dominant species, ones that move left, and ones that move right.

[@YesNowGoAway]

Two thoughts: - You're wasting some perfectly good creatures by counting backwards distance as negative fitness - Instead of outright banning loops, add some damping to muscle movement. That way, twitching would still be possible, but largely useless.

[@shootingblueyes]

When the creatures get more homogenized, you should increase the % of them that die. That way there would be more room for evolution because less of the same creatures would live.

I'm a bit surprised that the creatures didn't use the sin node to generate twitch.

[@cheydinal5401]

they probably did, but he didn't ban -1, but he created a computer program that recognizes all twiches, and then makes the parts responsible for that to constants

[@anonymouse6779]

No he didn't, he just banned the looping ones.

[@ZweiSpeedruns]

I predicted that they would use sin in the discord chat. Very very weird for them to use the bobbing to generate twitch

[@LaughingOrange]

[@2DReanimation]

Cos they're stupid ^^

[@ABunchOfRandomAnons]

How to take advantage of failures: Flip the negative-goers, instead of killing them. Kill all the non-movers. Now everything moves to the right and with a higher chance of awesomeness.

[@Owen_loves_Butters]

Natural selection doesn’t flip. You run the wrong way, you die.

[@RealCadde]

Ok, i have a couple of ideas. 1) Introduce energy. The more energy the creature uses on it's muscles, the faster it runs out of energy. Each node provides a certain amount of energy to the combined energy pool and each muscle movement will subtract from this pool. This makes more complex creatures have an advantage at the expense of complexity (more chance of bad mutations) and more muscles having to work to move it. EDIT: This would solve the spastic movements. So much energy is being wasted on just spazzing out. 2) Instead of giving each creature 15 seconds to do it's thing. Give it 2 to 3 seconds to get moving and then "chase" them with a "death line" that moves at an exponentially faster and faster speed. 3) Instead of letting the "leader" survive with a random chance of death... Which practically means it never dies... Just make it die anyways after X number of generations. If it cannot make offspring that either excels it or at least matches it's performance you will see bumps in evolution that may very well fade off into non existence because this generation simply cannot evolve past that certain point. This gives other species a chance to enter the race when they are just as the mid point. 4) I don't know how good of an idea this will be but i was also thinking that you would divide the species up into their own brackets. Thus ensuring a certain species will still exist at the brink of extinction for longer. Sort of delegate at least 3 slots to each species that will survive no matter what happens. The best of each species are still in the running so to speak.

[@dariusduesentrieb]

8:53: "i kinda forgot everything that happens in this seed so i'll have to remember on the fly but i think i can do it because i have an amazing memory." It seems like when you spoke the last part of this sentence you forgot what you said at the first part.

I think you should apply an absolute value and count creatures going to the left as well.

[@youraveragebarofsoap8283]

If you're running away from a predator and you run backwards what do you think would happen

[@m1lkweed]

Or It could get flipped, for consistency.

[@GelidGanef]

If creatures that went backwards still got counted, but got flipped for the next generation, that could add a lot of new improvements. Sometimes when the top creatures seem to have stalled out, a really great creature will pop up at the very bottom, going the wrong way, then die next round.

[@OrchidAlloy]

+GelidGanef Exactly. Many creatures are so much better than the rest (Like in this video; 6 meters compared to 0.3) but in the opposite direction, and it's not fun to just see those die and not develop.

[@fablungo]

+GelidGanef you can't just flip them because a pos-x node won't behave the same.

[@OgotuMusic]

Kept checking my steam notifications xDD

[@serubyne57]

Same here.

[@clayton8or]

i got so annoyed and closed steam because i thought it was going berserk

[@RedstoneQwerty]

I'd love to see some really big creatures using these rules, as they could do much more complicated math and actually "think" about how to go farther. Would be fun to see just a massive "brain" with little legs doing a bunch of complicated math to find the optimal way to move itself forward. After a few hundred or thousand generations, the creatures could probably find a way to balance and move their muscles in synchrony

[@logiclrd]

+carykh: I have a couple of suggestions -- 1) Make the simulator automatically flip creatures with a net negative movement, so that you keep interesting structures that happen to go really far left by default instead of right (in other words, make the criterion be the absolute value of how far the creature moved, rather than the unaltered x coordinate), and 2) Replace time nodes with oscillators on various harmonics -- sin(t), sin(2t), sin(3t), sin(4t), sin(5t), and the same for cosine. Supporting sin and cos as functions where the input *might* randomly be the time isn't good enough, because the multiples of time that provide input to the creatures will be random, if at all, which in turn means they can't form repeating patterns over time; they won't line up.

[@SioxerNikita]

+Carykh I think you could improve Simulator (although make it more gradual) by making creatures have less children. Kill of only like 250 or maybe even as low as 125 and randomly pick (weighted towards the creatures at the top) who to give birth to a new one. This might allow you to have more convergent evolution and several species evolving side by side. What I see a lot in your simulator is one creature did something good BOOM! it replaces all other possible designs within a few generations killing off any potential growers. EDIT: Other stuff I thought of. This will stale some creatures to survive for many many more generations and maybe to add more variations give a slight chance per step of survival randomly mutate the surviving specimen. Something like 5-10%? May lead to the top dying but will also give a chance for other stuff to hit the top.

[@KohuGaly]

the reason why that is happening is because there is only one way of survival (getting further to right). Evolution is based on fact, that reproduction has exponential characteristic. The ratio of two exponential growths is still exponential. Because of that, when you have two creatures with unequal reproductive capability, the one with greater growth will take over exponentially fast.

[@SioxerNikita]

I understand all of these things and my post implies that as well, but you don't seem to understand that my suggestion here is actually addressing some of these issues. The first part: The top creature almost always survives and it ALWAYS reproduces which means that it's children already has a higher chance of surviving since it came from a greater gene Pool, which means it will phase out other creates high on the list (but just not that tiny bit better) extremely quickly, this leads to the very rapid overtake of specific species. The second part: This allows the evolution to become much more gradual and allows much more variation to enter into the gene pool and stay in the fight. If you only kill of 25% of the creates there will only be 25% of the gene pool that births a new creature. This makes slightly sub par creatures more likely to stay in the gene pool for longer and as long as it is at the top 25% it has a much higher chance of getting a better variation produced since it will stay around there for longer and most likely have more iterations produced. An addition to that idea I have could be to allow a creature with a small chance to receive a mutation without giving birth. That could lead to more variation as well. Everytime I listen to Carykh he seems to be interested in the fact that interesting things pop up but with every simulation he does one type of creature beats out the other ones very fast most of the time. Another thing he should do is create a little screen to show the best, median and worst creature of each species as well, will give him much more interesting information and allow him to see what makes each and every creature type fail or falter.

[@cheydinal5401]

good idea!

[@cheydinal5401]

+KohuGaly That would still happen with 125 deaths/generation, just not with 2^x but 1.25^x or so

[@SioxerNikita]

Cheydinal Also with randomness since the ones to reproduce would be selected at random and therefor would be a bit lower and give some other species a chance.

[@GarryDumblowski]

About that really fast backwards creature, you may want to sort them based on absolute value so that really fast ones like that don't just die off because of the rules of the game, even when they really deserved to live.

[@martind2520]

Notice how at the end the best creature stops almost exactly after 15 seconds. This is the testament of evolution. The parameters are kept to exactly. The early creatures keep going for a while but stop early, but by the end the creatures stop _exactly_ when it is pointless to keep running, no sooner and no later, and all without ever being designed to do that.

Generation 70 had a breakthrough, too. Unfortunately, that creature went backward. :( And it's a crazy shame that the best creature was the very slowest one from the first generation, but it went the wrong direction. In the first seed.

[@hoseja]

Don't ban loops, add hurdles. Make twitching non-viable, not impossible. Ah well. You're trying to make things pretty and comprehensible, that's not how evolution works.

[@fergf3065]

One interesting factor would be to kill off 10% of the largest population if no significant improvements have been made after a certain number of generations. This would allow the other species to have a big more room and would have more variety overall. There might be better species, but if an early leader squeezes out competition, they won't have an opportunity to try different things. There is no room to try different things and fail.

[@roberthelm41]

discredit the negative penalty and make the distance an absolute value. it doesn't make any sense that you are programming the organism to only go right. you would get better results if you counted both left and right distances

[@roberthelm41]

yes do this please

[@DatMilu2K]

as in real life u can do very bad or very good ;)

[@luckyshadowtux]

or you could just change the parity of some variables to flip it, and have its children go to the right

[@roberthelm41]

***** lol I suppose so, but this simulator doesn't pose such a question. I was merely stating that you would get more varied / interesting results if they were allowed to flop in either direction :) no worries

Well, the first evolution video did establish the hypothesis that the creatures were escaping from a predator, e.g. a bear.

[@SirCutRy]

You should run it for like 10 000 generations, at least. And then check the breakthroughs.

[@supercat765]

I think it would be interesting for there to be a "god" tool so you can alter creatures I know it kinda defeats the purpose of an evolution sim but then you could see if replacing the time node with a constant 10 would be better and how it would proliferate even though it was not natural

[@justinwhite2725]

If you can flip them horizontally, you should make the metric absolute distance and flip all the ones that moved backwards. It would be interesting to see if the design that went -7 meters on Gen 1 could be improved upon! @27:00 you talk about needing two mutations - are you only doing one mutation per generation? You should have a chance to do multiple mutations - like say a 10% chance each pass to do two, and if you get a second mutation that also has a 10% chance to do another mutation. That way you can have many mutations and possibly get a completely different creature which will increase odds of improvement. In this specific case - it doesn't want a constant instead of time. The time is important because the muscle grows and it causes it to 'launch' into the air. If it was a constant it wouldn't be able to launch itself.

[@hawthornrabbit]

Absolutely amazed by this brilliant node-math setup!

[@PretzelBS]

My favourite creature is definitely the one that got -7 METERS IN GEN 1 THAT’S INSANE screwing up the proportion of the graph. What a legend

[@BountyLPBontii]

I had to laugh so hard at the worst creature which is like almost genius in the wrong direction!

[@nikzuLP]

Why don't you vertically mirror creatures which go to the left? That way no creature which is very good but goes in the wrong direction will be killed, but can improve to get better!

[@SUPABROS]

Nope. In his first video he sayed itrs random.

[@InvalidOS]

6:20 I wish that for creatures with negative fitness, you just flipped the creature around for the next generation, and used the absolute value of their fitness. Then creatures like this wouldn't have to be killed just for going the wrong way. Would this cause some weird issue with the sim to pop up?

[@marcelwinklmuller5622]

shut up your steam DD:

[@EHMM]

KID.

[@kravenoff42]

one thing you might try to allow for more complexity over time is introducing the concept of dormant nodes and axons. this would act a little like junk DNA which can randomly get turned on or off which would make it possible for ideas like a constant that changes to get introduced at some point

[@cheongziyong8871]

You should do these based on displacement instead of just rightward distance. Imagine how much faster everything would've went if the 7m creature from the first generation stayed.

[@owenkanaal3457]

Love the long videos!!! And the evolution sim. You're inspiring me to dust off some python physics engine/reinforcement learning stuff I played around with. RL is pretty different from the evolution approach, since you can design the look of the creature, then search for the the optimal actions it should take (joint torques) through random trial and error. Will try to get a video up soon. Thanks again for these, they brought me to your channel and the wonderful world of TWOW too!

[@espen990]

You give these creatures a certain set of rules, and they evolve to make effective mechanisms? That's... really cool. I have barely an idea what coding is, but this looks like really good work.

[@mcnica89]

I did a similar evolution project once: I got a lot more satisfying walkers by changing the objective function from "Distance travelled" to "Distance traveled / (constant + energy used)", where energy used is calculated by integrating how much work the muscles do. This way you see them evolve away any useless movements that waste energy but don't add to the distance travelled.

[@galalon2]

again refering you to the last video, If you want to stop the twiching, don't ban the local stuff that make twiching happen because there will be another way. for example: this time you banned loops, but a time elapsed node could be muliplied and fed to a sin node to produce a high freaqency oscilator, in other words, a twich. I suggest you wold make the muscles move slower- meaning they will obey the neuron which is attaced to them only once every some frames (lets say 24- for a second).In that way there isn't a possibility for a twich because the mucles can't move faster than a certain rate. Moreover, this allows the neurons to make all the nesseccery computation before the muscle move, which is how real neurons work.

[@thomas6617]

Hope he sees this because i would love more interesting creatures

[@zasharan2]

The timer is important because if the py comes to an absolute rest, the lengths would stay the same forever. The time multiplier gradually increases the length which also increases the py making it faster, and that also explains the pausing, that's when the py is at rest, and it spasms again after the timer and py start to increase faster and faster.

That first "worst" creature didn't get killed by a predator, it *ran over* the predator and became the predator.

[@Double-Negative]

the time multiplier IS important. it's what gets the muscle extending again once it lands on the ground. the yp multiplier helps it push itself higher than the time would on its own, and retracts the muscle on landing.

[@aaronameerbeg1822]

Just a thought but if you split your creatures up into 2 groups those that travel positively away and those which travel negatively away, and then killed off half in each group using the same algorythm wouldn't you create more diverse result so you could get creatures moving so far in one direction but the creatures travelling in the other could be doing significantly better?

Instead of sorting them by how far they can move right, you should absolute value the distance to sort them by how far they moved from the center (left and right). This way you won't have to kill off some amazing creature that just happened to move left instead.

[@jekanyika]

It would be good if the simulator measured the distance travelled from the starting point so that any creature that travels backwards can be mirrored and kept in.

[@hawthornrabbit]

Also, I love the way the music interacts with your commentary around 18:20 XD

[@yushatak]

I don't see why moving left should be an invalid result - why not just treat their absolute distance as the result, and if you want the animations to look uniform then flip any left-moving contenders.. By having anything that goes left be at the bottom of the barrel during sorting you're removing a lot of strong results that could contribute.

[@Owen_loves_Butters]

Natural selection doesn’t flip. You run the wrong way, you die.

[@mgames3209]

I agree but this comment is 5 years ago

[@nicksmith6535]

Can you make the ground randomly uneven ? It would be very interesting to see how the creatures evolve on unflat ground.

[@mincrmatt12]

"it's all floating point rounding errors" I gotta use that one sometime!

[@brad1ey50]

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

[@kevintrigg3707]

I think that you should change it from distance to the right to absolute distance. you see some spikes in the negatives of -7 and such which could be good but are killed off so instead of killing the bottom kill the medians or the like

[@LeafShade]

My idea was to mirror the worst, then have the middle be cut out instead of the bottom.

[@zombiefritteuse]

Indeed. Also, that first "worst" creature looked really promising, motionwise :)

[@spideroi]

You mean, taking the absolute value? It DOES make sense, but then it doesn't. Because in a survival situation, if you're running toward the predator and/or away from food, even if you're very fast, you'll die.

[@2blocksonthewall4253]

only thing i saw was IT HAS A WHEEL!!!

[@Mina_Meow]

Some creatures in this video kinda look like running cats in their movement, thats really cool also, I wonder what would have happened if that 1. Gen. worst creature would have gone in the right direction, it was very impressive and it's fun to see how long its distance was unbeaten^^

[@balkaranmali1091]

I did this using your program and I got S45 dominating everyone. I did it up to gen 300 and the highest was 16 m and median was 15.4. It's nice to see how diverse evolutions could be mine was completely different. Mine was like your first video on this.

[@GrouchyGander]

I think you should've given the gen1 S33 a chance. I mean sure, it went the wrong direction, but what if a predator was in front of it, forcing it to go the other way? There isn't technically "negative" movement, after all.

[@SockTaters]

Cary, I know this might be difficult to do, but it'd be cool if you made some way to manually create a creature that could be input as all 1000 creatures to be perfected by evolution.

[@peeelan]

I find it hilarious that a creature from the very beginning made it farther in the wrong direction than any other creature went

[@deltainfinium869]

This displays how the rabbit evolved. The little guys have the exact same movement pattern as your triangle leapers

[@juppso]

That steam message fucked me up

[@redberry2443]

*Hi, I have a suggestion:* You know the game "QWOP" ? (a man running by moving thighs and calves) Well, I manage to run as a normal human. And I want to see if with genetic algorithms it can produce the same way of running... And with different settings it would eventually (I suppose) get there.. (e.g. if you allow knees to touch the ground, probably you'll get a static crawl just by twitching the calves rapidly,, else you might get a more of a robotic walk, high frequency movements, if you ad a constraint on the time of switching movements I think it would become human-run) (There is a program out there in java, but it uses the actual QWOP.swf and analyze just the score from the image,, What I want is to have real time simulation of a creature that has blocks (2 feet, 2 calves, 2 thighs, 1 body, 2 arms, 1 head) pivoting on each other...) I'll be happy to hear what you think (P.S. it would reuse a lot of your initial code, it just needs to change the changing-length-muscles into a rotating join, and for example a thigh would be two rigid circles connected with one fixed-length stick)

[@raffimolero64]

i'd rather be running AWAY from the predator than going left TOWARDS it lol

[@arthuristehbest]

These videos are so interesting, I wonder what would happen if a certain percentage of the population is always random and the program was left running for millions of generations... maybe they’d break 100m, maybe they’d start jumping, maybe they’d band together and form skynet??? Who knows... so interesting

[@dkkempion8744]

Congratulations! You've reinvented... Frogger. :| :D

[@raffimolero64]

[@klumbdoltone2255]

if you want more different creatures you should give different environment. because the creatures will tend to the most efficient way to go. but if there are different environment the creature could choose different way to achieve the top and survive

[@timstroud7963]

Another thing that might be a good addition is the introduction of rigid bone like connections and flexible elastic nodes so they want to snap back into place with a variable tension

[@Jo-de3st]

To improve the simulation you could: -make time nodes be able to start above 0 -make a new node that detects whether or not it is a certain value (input or constant on node), which will then send out another value (input or constant on node) -not kill creatures that went far in the wrong direction, but the ones that didn't go far in either direction (you could maybe mirror their nodes) -change it so just about 250-500 are killed and those slots are filled by children of the rest (you could use the killing algorythm but for children on the surviving) -include two fitness values (distance and highest reach?)
