    It's interesting how the prey cap seemed to play an important role in the simulation- when there was one big preyblob left, it seemed to have all of the prey in it, so no other prey could really reproduce, but when the predators were able to start breaking up that blob, the prey population suddenly exploded over the whole rest of the map

      So when there are a lot of prey, they need more energy to reproduce. Theoretically, they could get an unlimited amount of beings. However, they won't as reproducing gets more and more expensive.
      On the other side, Predators consume more energy, when there are already a lot of them. This should too result in a soft cap.

    My theory at 19:40 is that over time, as the prey in the center replicated, they slowly lost some of their evolutionary traits that helped them avoid/eliminate predators; there wasn't any evolutionary pressure to keep those traits because they were relatively well protected by the prey on the borders. So, when the border prey were killed, it left the center more vulnerable.

The prey in the middle of the blob were sheltered from predators for a very long time, so they didn’t get a chance to evolve accordingly. When the predators broke through the first strong layer, they were visited with a bunch of under-evolved prey that they could easily eat

    A critical mechanism for prey that seems to be missing is food source. There is no incentive for prey to NOT clump together and stay in one place.

      Yes! Even better if the food source coevolves with the prey, just like in Huegene. That way patches of different colors would naturally emerge, possibly creating different niches and boosting speciation. Might be even more interesting if the predator's prey color preference also coevolves at the same time with the prey color

      We can assume they live in a nourishing substrate. But it would be good not to cap max number of pray but max number of pray in certain area. Or maybe chance to reproduce depending on number of pray in the vicinity.
      Also 4 hits to neutralize a predator is too much IMO. Better predator eat pray in one hit but pray deactivates predator in 2. Or randomly with some chance e.g. 50% or 30%.
      Could be interesting to explore the idea of predators eating predators too.

  • @gavinoaw
    @gavinoaw ปีที่แล้ว +1103

    I think what happened at 19:20 is that after the collapse of the Corner Prey Blob, some predators managed to migrate to the Center Prey Blob, where the prey weren't adapted to deal with the corner predators' aggressive strategies. The corner prey had evolved alongside them, so they were better adapted to deal with them, but the center prey were by that point probably a totally different species, who didn't have the traits necessary to defend against the corner predators. I'm guessing the center predators also quickly went extinct when the corner predators started expanding, but that was something we couldn't see, because they looked the same. In other words, the Center Blob had a relatively balanced ecosystem, which got destroyed by an invasive species, and then a new balanced ecosystem emerged (the scanner ecosystem).

    • @legendarydragoon

      I agree with your theory and as such think it would be a cool addition to assign color coding to "genes" or values of the entities that are mixed in some way and rendered as their body color. That way we could start to see groups of species with similar traits visualized separately. The stronger the divergence in values/tactics, the greater the differentiation of color.

      i disagree entirely.. the issue was the population cap, the prey was at cap for most of the simulation, and as such even a colony that should have been fine, holding its own against the predators wasnt able to reproduce at certain moments, and instead, prey in the middle of the map or in another colony reproduced, and every time that happened, the predators gained an advantage, as each of their packs never decreased in size (enough of the predators roamed the empty space and died, so the predators reproduced and were immediately attacking where it counted) at least until the colony was wiped out.. the only time the prey population dipped, was when the predators started chewing into the last blob colony, it was essentially all the prey concentrated into one spot, with a few random stragglers out and about.. the colony was able to sustain its reproduction, because all of the new prey were going tot hat colony.. until enough of the roaming predators died off, and it became all of the predators attacking all of the prey in a single point, and the predators have a 2x advantage in an equal fight, and that eventually lead to the reproduction rate of the prey to fall behind the consumption rate of the predators.. luckily at this point enough of the roaming prey managed to reproduce enough to self sustain, but then the colony disappeared, and it became a slow wave of propagation and death
      Solution? totally uncap the predator population.. and cap the prey population to a multiple of the predator population (otherwise the prey will just fill the screen killing the predators) this will allow the prey to not be 'at cap' most of the time, and if a colony gets surrounded, that colony will die out, but it will allow other colonies to explode in population (because the predators exploded in population)

If you watch closely, you can see a small few groups from the second to last colony survive a journey to find the last colony. That trait that allowed them to efficiently kill a colony _AND_ find the last colony got replicated, which seemed to aid in the creation of the stable "scanner" ending.

    When watching the timelapse, it almost appears that the "super predator" (the generation that could somehow destroy the prey with ease) didn't develop in the main large blob of prey, but actually in the other major blob on the map. At 26:45, you can see a sudden change where the predators go from eating the prey on the outskirts of the upper right blob to completely decimating it. Then, when it is completely destroyed, most predators die soon after. However, it looks like a few predators from that area managed to randomly wander over to the other blob, and the places they wandered to is exactly where its complete destruction started. It's just a theory, but its interesting if it is true.

      This is correct. Though I'd love to see some tweaking of the population limits. It's not really a fair test if the prey run into their population cap.
      Another really interesting thing would be adding a colony of human controlled predator, using RTS like controls perhaps, and seeing how that would work. Also, if you think about it, the predators at the end achieved a perfect scenario - they kept enough prey alive to continue propagating while they pushed them endlessly north, eating their fill. They didn't eat them all and die from starvation but instead got to a point where they could continue to feed forever.
      Man, there's so much to think about with these kinds of things and I'd be so interested in the results after tweaking various parameters. Like how does it change if there's not "endless space", so they prey couldn't just continue north forever? How would it change if prey had a short range of vision for predators but had an extra sense that could detect fellow prey from a long distance, like a scent or sound analogue? I honestly wish I was capable of this kind of programming, it sounds endlessly fascinating.

    1. Instead of keeping the prey stuck with a short range of vision but a wide field of view, and the predators a long range of vision but a narrow field of view, both kinds of entities should have an "eye shape" gene where vision range and field of view are inversely proportional to one another.
    2. Have a third kind of entity, "plants", which are eyeless blobs that can't move on their own, but stay still and multiply if kept alive for long enough (Prey don't do this anymore - their reproduction is based on how any "plants" they've eaten, like predators). They're eaten by prey, and while predators can't eat them, they can push them around (maybe they can develop weird strategies around this, like a wave of predators carrying some plants around to attract prey).

  • @u0068

    Lots of ideas:
    1) I think that a good way for prey to communicate would be pheromones.
    The prey will be able to produce and sense pheromones as a response to stimuli such as 'i see lots of predators' which would allow for complex behaviours and strategies. Maybe predators could also use pheromones, possibly even sense the preys' pheromones which would allow for even more complexity.
    Also there could be multiple different pheromones, for example red blue and green, which the prey could evolve to signal different things.
    How pheromones could be implemented in the simulation:
    Particle Approach:
    Upon stimulation, prey will release pheromone particles which other prey could see or smell.
    The number of particles they can sense will be proportional to the activation of the sensing neurone.
    Pros:
    Easier to code i think.
    Works with infinite number of pheromones
    Cons:
    Seems quite cpu intensive, as a lot more raycasting will be needed to see the particles.
    Image approach:
    Rather than the pheromone particles being an entity in the simulation, they will instead be represented by an image that overlays the whole simulation area. The RGB channels of the image can be used to represent different pheromones.
    Upon stimulation, the prey change the RGB values of the image at its position. For example if the coordinates of the prey are 20, 30 and it releases a red pheromone, it will increase the red value the pixels at or around 20, 30.
    Diffusion and dissipation of pheromones over time can be simulated by simply blurring and dimming the image every frame.
    To sense the pheromones, the prey would simply check the color at its coordinates, or take an average of the surrounding pixels.
    Pros:
    Runs a lot faster because its just performing basic operations to an image.
    The can be low resolution and still have full functionality.
    I think it would look cool to have the image as the background of the simulation.
    Cons:
    Complicated and harder to code,
    Only works for 4 types of pheromones, red blue green and alpha
    2) Colors:
    Each entity will have a color gene that affects its appearance.
    This could be purely cosmetic, and show genetic drift as the entities mutate, which will allow us to distinguish between entities with different genes.
    Possibly, the entities would be able to see the color of other entities. This might lead to interesting behaviours, such as xenophobia ( prey preferring to group with prey with similar color because similarity=relatedness and grouping with related entities would help preserve its genes).
    Another possibility is that the color similarity of entities it sees will replace the 'object type' input, however this may encourage mimicry; predators to evolve a similar color to the prey so that the prey cannot distinguish it from other prey or vice versa which is quite OP but sure is interesting.
    3) Eyesight gene:
    A gene that both increases vision range and decreases field of view, allowing these traits to evolve over time rather than being set at the start of the simulation.
    4) More layers in neural network:
    The current neural networks appears to only have 2 layers.
    Adding more layers of neurones will greatly increase behaviour complexity, at the cost of performance.

    It looks like you essentially have 2 species of predator. Those that work together to from a front, and those that work alone to pick off stragglers. It would be interesting to have some way to indicate lineage. The first thing that comes to mind is color: having color be something that can mutate randomly as well. This way, if a particular mutation is successful, you can see it propagate through the population. I imagine you could switch between having them just be red/green vs showing their color for analysis of lineage.

    There are so many cool directions this could take! Prey could experience two states- a "calm" state where they reproduce faster, and an "agitated" state where they move faster. Prey could learn to recognize the state of other prey. You could add cover- places in which prey could hide which are energetically expensive for predators to destroy. You could give each entity an "energy level" and monitor the trophic dynamics of the system. Excited to see what's next!

    • @Aegilops

      Great idea about the cover-places. My feedback would be to widen the cone of detection rays so predators and prey could be more aware of other entities to their sides (or behind?), but more significantly, stop the edge-warping in the model. The final display of the "rake" by the predators seemed false as the prey were respawning "under" the wave for the next wave to wash through the map - this would be very different if the edge of the simulation reflected real-world environment limitations (cliffs, coast etc). So, sure, the predation wave would be devastating, but then you're left with a swarm of hungry predators with nothing to eat.

    • @Nerdnumberone

      I wonder if the defensive strategy might learn to flash agitated to call allies to the line, but then go back to "calm" even on the defensive. If they are holding the line, reproduction speed might be more useful than speed.
      It might also be useful to have a way for prey to send an alert that other agents can detect, even if it isn't in their cone of vision to symbolize a distress call. This could cause nearby prey to either run or prepare for combat. Prey might not bother with the alert so that unaware prey may distract the predator chasing them, but the distress call strategy could indirectly aid in the survival of the behavioral trait if close relative (who are more likely to share the trait) survive because of it. This is a rather complex behavior to learn, however.
      I wonder if having a way to recognize their close relatives would be useful. Related agents are more likely to have similar strategies and might be more reliable in a pinch for altruistic agents.

What if you add a "light" on the back (similar to the eye) that turns on when they see a predator, and this light can be seen by the other preys (maybe by predators too, just to see if it has any effects on their hunting strategies). It could also have different degrees of intensity, for example if it's seeing a predator the intensity is 5, if it's seeing a prey with an intensity 5 light then it emits a light of 4 and so on. This might give the prey some knowledge of the direction where the predators are coming from.

      It would be fascinating if the prey could choose the light intensity on their own by the inputs they get. Similar to how the output of the neural network helps them move, a smaller net could be created to interpret their inputs (surroundings) to shine into a light intensity from 0 to 1 which can be interpreted by it's peers. This makes for complex strategies for both prey and predator. A prey could interpret the inputs of another prey and deduct what it itself needs to do, responding to the light with its own movements. They could even keep responding to each other in a chain reaction of lights blinking. You could technically imagine these creatures strategizing, if these lights actually impact the output of the movement.
      You could separate different kinds of preys and their talking methods in separate colors. Since different mutations of preys are varied around the map, you could try dropping some preys from the corner of the map to the other corner to see how they react. The same could go for a predator too.
      Taking this into even more complexity would be if predators could see the lights of preys. This could mean counter strategies from the predators.

    It almost looks like Prey stopped "standing it's ground" in giant blobs, and just started backing off. As the Predators start "scanning", you can see Prey is dispersed and moving in the other direction (because the Predators behind the wave die off from starvation). Ergo, it's stuck in a loop.
    Edit: I know it'd start getting very complex, but it'd be interesting to implement a % chance for offspring to be born with a new trait, picked randomly from a large chart. All traits can be passed on (but not guaranteed), and can even be improved further (like leveling a skill in most games). I.e., increased sight range, slightly faster movement, birthing twins (or litters), etc.

      This is a result of entropy more than chaos theory, but there are elements of chaos there. Partly that chaos is restricted by the map boundaries, that being a square shape allowing the repeating predator sweeping strategy. But what we see here is entropy hitting its highest point due to order seen in the predators' behavior. The phalanx pattern and emergent sweeping strategy are examples of order that allow the highest population of predator and prey. Given many more variables akin to a food chain, we could see more and more resemblance to entropy in the natural world, but that isn't necessary to understand how this simulation emulates mathematical entropy. If entropy became this high in the natural world inside a closed box, the prey would likely start to die off too fast for the predators to thrive as they did here, simply because they are reproducing at a sustained maximum rate across the entire map given a specific period of time, and they would likely use up the entire map's resources (again, the food chain variables) before those resources could recoup.

    19:08 The predators started winning because they (probably unknowingly) created a "wedge formation" that was once used by cavalry to break enemy lines. The wedge was shaped in a giant triangle, charging the enemy crating a "gap" in their lines where more of the predators could pour into, and hopefully split the defenders into two smaller groups.

  • @KingOreo2017
    @KingOreo2017 ปีที่แล้ว +228

    These videos are all so amazing! Heres a few suggestions:
    1. Reduce the map size. Maybe make it 4x bigger than the original rather than 16x. I say this because I feel that the population cap creates an unrealistic pressure that may look cool but causes weird things to happen. The smaller groups in the beginning are what cap the larger group in the center from reaching a larger size, and I feel that that is unrealistic.
    2. Create some sort of "grass" the prey must feed on. I noticed throughout the simulation that the reason the predators couldn't break in and kill all the prey is because the prey in the center of each group basically just reproduced, creating thousands more of themselves which just threw themselves into the predators to keep them at bay. This basically meant that the prey didn't really need to evolve and caused the boring (but very cool looking) end where the predators just swept up and killed any prey they touched. A type of grass system, which could just be a value that by default increases by 1 every tick and decreases by lets say 5 every tick, wouldn't allow the over density of prey that is seen in this video
    3. Make different species. I'm not sure how viable this is, but I noticed that the predators seem to split into 2 (maybe 3) different "species." One was the main line, which just rammed into the prey and tried to kill them, the swarm, which sat behind the main line and got any prey that dared to escape, and the nomads, which stayed between groups and killed off any prey groups that got too big. Maybe creating some sort of system that changed them different colors depending on how different their neural networks are could lead to some very interesting results.
    4. Allow communication. I know you mentioned this in the video, but allowing the prey and predators to not only see each other, but to communicate, could create even stronger packs like were seen in this video. Prey could send off some sort of warning to other prey that they are being chased, or maybe even a fear response if another prey dies around one, and maybe the opposite for predators where a predator could tell others that there are prey nearby. I feel this would be very cpu-intensive and may not change the end result that much, but could be interesting to experiment with nonetheless.
    5. Sexual reproduction. A small change, but maybe create a system in which you could toggle on sexual reproduction. It may not make that many differences, but could be an interesting thing to try and many change the result of an experiment if some feature you add keeps giving the same result.

    for prey communication you could give the prey a new ability to give a pheromone (a float between 0-1) and a new sense that averages the pheromone of all prey in a certain range. I hypothesize you'll see a few things from this. 1.) groups will form with "languages" will form where the group has begun to communicate and respond to communication and react to predators more effectively. 2.) when prey from other populations are introduced into new populations they respond in unexpected ways because they don't understand the group "language" 3.) if and when large populations of prey intermingle causes erratic behavior until population collapse eventually one language strategy remains

    Worth the wait! There's definitely some interesting emergent behavior here. Wow the "wavefront" behavior was really cool! A couple of things I thought about:
    - Could you offload some frame computations to the GPU to improve frame time?
    - What if the entities had two dimensional size and didn't want to occupy the same space as other entities? You almost certainly couldn't do this without improving frame time before, but maybe some rules similar to components of Boids.
    - It would be cool to show a total count for each group on the graphs.
    - You probably did this already, but create a way to serialize the simulation state so it can be resumed. Include separation of the ruleset from the state plus definable migration for incompatible differences so that you could resume a simulation under a different ruleset.
    - Show average offspring count, average kills and average lifespan in ticks for each entity type.
    Some other really good ideas in the comments! You've got a lot to sift through. Looking forward to more!

      Is the Boids suggestion inspired by the bibites’ usage of the boids system? Because bibites seemed to use boids for asocial behaviour to prevent viruses, and because being too close to eachother would cause them to deal damage. Here, though, Seperation would probably be ramped down where Cohesion would be ramped up, merely using it for even more extreme pack hunting.

    • @TheYeetedMeat
      @TheYeetedMeat ปีที่แล้ว

      The best thing to do here, to improve upon the rake behaviour rather than removing it, would be to add obstacles that can be detected and not moved through, and add a “fertility” mechanic where prey would get slowed increase of energy when moving over a recently moved over patch of ground, but the fertility of ground would slowly increase back to full. These two properly implemented, I predict, would result in rake behaviour developing slower (since the dominant prey-blobs the early grouper predators developed for would not arise), and prey getting the opportunity to go through gaps in the predator line made by obstacles, getting higher fertility land temporarily.

  • @fastjimmy6167

    Amazing video! I’d love to see two new behavior facets:
    One - recognition of when a fellow Prey or Predator is a “relative” of you; something like knowing whether the Predator or Prey next to you has a common ancestor two or so generations back. I’d be curious to see if Prey group up less with those who aren’t “family” or if Predators would consider non-related Predators competition.
    Two: “Grass” for the Prey. The prey passively have more energy than the Predators, but it would be interesting to require them to eat another resource, which could lead to some migration or even defending resources. In addition, it would be cool if “Grass” randomly grew everywhere, but would generate at a higher pace wherever a Predator died. This could create very interesting feedback loops where Predators who overeat Prey to “extinction” would ultimately bring more Prey back into the area, avoiding the inevitable “clumping” or the interesting (if semi-boring) “rake” behavior we saw towards the end.
    I would love to see what else you come up with! Keep doing good work!

      I’m going to go off on a limb and say that prey will actually group up with more distant relatives, to ensure that if one dies the others will not. This has little benefit, but it seems grouping up with relatives will have very little benefit if they can’t defend themselves. Edit: Such a behaviour would also prevent clumping, meaning if one hit the jackpot and reproduced without predation for a short timespan, it would split up and not have most of its genes become defunct mutant individuals.

    An idea, if I may: perhaps preys could have to seek food too. Maybe each cell of the map could have a "grass" value that increases (or, should I say, "grows") over time. When a prey enters a cell, it eats some or all of the available grass and thus increases its energy, much like predators do when they eat a prey. That would force preys to move and would also naturally cap their number, without the need for a hard population cap.

      16 bits seems like a lot, especially if you wind up using a single bit to encode positive/negative messaging, and the other 15 for various common situations. It also opens the door for organisms to 'misunderstand' the instructions, or even intercepting the other side's scent signals, much like how Toxoplasma Gondii rewires the mind of mice to be attracted to feline scents, rather than repulsed.
      Of course, if he's going to add that, he might as well go full-bore and rework reproduction too, adding gender and requiring a pair to breed and mixing the parents' neural nets as well as some variance.

      Khatharr is 100% right here, it's because the shortest, straight line here has the least energy (not energy as in simulation energy, but some abstract quantity that will tend towards a minima). If you wanted to actually go through the maths to work it out yourself, then you could use the Euler Lagrange equations and principle of least action to show that the straight line has the least cost.
      To explain it more intuitively, imagine some loop in this space (it's a little annoying to think about in this particular case since the space is a torus I think but point still mostly holds). Then, imagine some kink in this loop. This kink is going to have a higher ratio of predators : prey at that point compared to unkinked sections, and therefore it's going to tend to recede. If you keep having these kinks suppressed over and over, eventually your loop will settle towards its minimum length, i.e. path of least action if you want to use the mathematical phrasing.
      It's the *exact* same reason for why in world war 1 and 2 these huge salients would tend to collapse down back into more simplistic lines. It was obviously muddied there as there were things like terrain, supplies and so on to change the cost of any particular shape, but the principle holds.
