[@nyphron3109]

Correlated interaction! One of my favorite parts of evolutionary game theory. If team try to find team, and solo try to find solo (or don't care who they find), then cooperation will evolve so long as the team blobs find each other enough. That point is determined by Hamilton's Rule, and is actually a pretty neat piece of math. It was initially devised to deal with how altruism applies, but because of some game theory shenannigans, it applies here too. On the other hand, if team try to find team, and solo also try to find team (they do better against team than solo blobs), then it's mathematically like there's no correlated interaction at all. Hope that helped!

I'd love to see a more complex simulation where, rather than the blobs dying after a single round of gathering, they instead do multiple rounds first and remember who the solo blobs are. A few other ideas to make it more interesting are: -Sharing with blobs who got nothing. -Solo blobs that will try to steal from teamwork groups. -Blobs who change what they do depending on how other blobs treat them. -Larger groups who get less each, but can block solo blobs. -Smart blobs who wait to act selfishly. -Traitor blobs who work with each other, but are selfish against team and solo blobs.

[@SansULB29]

Hmm interesting... -this one kind of simulates charity. -this simulates stealing (obviously) -this is some level of emotion -this somewhat simulates tribalism/the idea that "we are stronger together" -basically simulates smarter stealers -this creates a new "faction" of blobs

[@Bozebo]

That's so difficult to build but it'd be fun. It's either get stuck implementing and experimenting with specifics; or you'd need to find a way to fractally have the game rules modify over time/generations and have ML decision making models for each blob as an agent and let the rest emerge "naturally" and then analyse what emerged to see if you incidentally created for example "traitor blobs who work with each other, but are selfish against team and solo blobs" and what they did.

[@SansULB29]

@@Bozebo ye..

[@nyphron3109]

Evolutionary game theory has answers for all those questions! In order: - Altruism can evolve when the ratio of blobs who share is greater than (penalty for sharing / benefit for sharing). That's called Hamilton's Rule. - This wouldn't make that big of a difference mathematically, because it's basically already happening. - That's called Hawk-Dove-Retaliator, and is a super famous game in game theory. Basically, you try to be cooperative, but if your partner attacks/betrays you, you attack them back. It turns out that cooperating can evolve if there are enough retaliators in the population to keep the solos out. But if there aren't enough, the solos will invade. - This one actually isn't classic game theory, but would definitely be interesting. It's basically a more extreme form of teamwork. I expect it wouldn't change much, though. - This would be the opposite of the retaliator from before: they go to cooperate, but betray anyone who cooperates with them. They wouldn't do very good, because they'd kill each other off. - This would be pre-play signalling (or greenbeard effect), which is a known way for cooperation to evolve. Basically, we make signals at each other, and if we both get the signal, then we cooperate. The issue is if the other blobs can learn: then, I could make the signal at you, you'd try to cooperate, but I'd betray you. So how well pre-play signalling works depends heavily on the constraints of the simulation. Hope that helped! Everything there is Google-able, too.

[@Mpkki]

Y'know, it would be interesting to see a harder system where blobs survive if they have 1 food and reproduce for any excess and keep the memory of blobs they met and can communicate in their under-the-same-rock groups, so that tit-for-tat could actually be a thing. For example, a team blob could change its behavior (if beneficial) if it knows that the second blob is solo because this solo blob interacted with another team player from the same rock home the day before, or the other way around.

[@belg4mit]

The key is that evolution *is* repeated interaction. Whether the same individuals ineract, or their descendants, the impact is the same in a stateless situation (no memory of previous interaction to implement tit-for-tat)

[@Dogo.R]

Tit for tat definition: The best strategy is to assume cooperation at first. Then if they act one-sided in that interaction then in your next interact you strive to exactly* negate the extra benefit they received from acting one-sided instead of cooperatively. Then then next interaction you assume cooperation again. This strategy performs better then all other strategies invented as long as you can keep track of who you have interacted with previously and whether they acted cooperatively or one-sided that last time. And this same strategy can be observed in nature... though animals arnt dynamic like humans. They cant really switch strategy within the same livespan. Their behavior is formed due to evolution instead. Also worth mentioning that the above is based on perfect information. The optimal strategy has many more features and complexities when there is imperfect information but it still follows this core aim. The extra stuff is just trying to deal with signal error.

[@Scrogan]

Only if the situation isn’t designed to produce a prisoners’ dilemma. If you were an authoritarian regime and wanted to prevent your citizens from gaining power, you’d make it more beneficial for them to turn on one another than to cooperate. See East Germany and the USSR. I’d also watch out for lawmakers and lobbyists doing this in the current age in what we think are liberal democracies.

[@atypicalprogrammer5777]

It would be interesting if the Blobs could only visit trees near their "home". (Edit I did that myself, see the bottom of the comment) I imagine a start with 50% solos with 2 Nash Equilibrii would result in a mix of "friendly neighbourhoods" where cooperation dominates and "battlefields" where fighting dominates. Edit: I made a simulation, with a grid of 32 by 32 worlds, each with 4 trees, and enough houses for 64 blobs. I used the same rules about blobs going to get food from trees and reproducing as in the video. Except each of my blobs can freely visit trees in their own world, and the 4 nearby worlds, and the blob's children can choose to move to a nearby world. I started with 1 friendly and 1 solo blob at far-apart worlds and looked at 256 turns. With the setup from 3:23 two "nations" formed, but (as some people below predicted before I tested it) the friendly nation eventually -- after almost all 256 turns -- was able to convert the entire world to its peaceful ways, by force. The friendly nation was able to sustain a much larger population, so enough friendly blobs "immigrated" to the unfriendly neighbourhood each turn, that they were able to cooperate with each other to get more resources than the "locals". Edit: My C++ code is on Github dot com slash nikolajRoager slash blobsOnLattice (I am apparently not allowed to include a link in a comment) The code is not tested on windows, and normal warnings about running random code from the internet apply.

7:56 - in these ‘battle of the sexes’ equilibria (there are two distinct Nash equilibria where players benefit from doing the same thing as their opponent), the usual strategy players will go for is to randomly mix your strategies based on the expected output from mixing the strategies in such a way. That’s the third Nash equilibrium in the problem, since there are (almost) always an odd number of Nash equilibria. Alternatively, since the game is repeated in this case, the threat of reverting to the inferior Nash of solo solo would generally encourage rational players to always choose team team to maximise their long term utility gained. Impatient players, or players that prefer rewards now than rewards later, might be willing to switch to solo and then have the other player also play solo forever. Haven’t yet got onto the bit of the video about evolutionary theory, where you might cover this, but that’s the continuation from within standard game theory :)

4:47 Hypothesis: if the percentage of team blobs are higher than the percentage of solo blobs. The team blobs will prevail. This is because while the solo blobs are hurting eachother, the team blobs cooperate with aneanother. And if there ever is a team blob-solo blob interactioj of different species, the team blobs will just one-up eachother with the best possible out-comes while the solos win't benefit at all if they aren't the majority. Vice versa if the solo-blobs are the norm. In game theory, I believe this might be similar to the prisoner's dilemma. As it follows the same genral reward system ( well, besides the alternative option of one for them-selves).

I feel like there is a flaw in not allowing the blobs to respond to previous behavior. Most cooperating creatures are also social enough to know and remember others and build some form of relationship. So what would happen if all blob pairs played, say, three rounds? In the first, they act according to their nature. In the second and third, they are able to respond to what the other blob did before. So if the other blob betrayed them, they would act like a solo blob with them in following rounds.

Because each strategy seems to be the most effective when it meets itself. Not that I took a little second to think about it, I suppose the team strategy has the advantage of spreading its numbers among themselves, meaning teams get a collective booth when they meet themselves, well solo only barely breaks even.

For example, during the section where you show the reward matrices, I would show the 3x3 grid, then when you’re explaining each one, make that situation fill out the whole screen, then zoom back out to show us where that situation fits on the grid. Another, less extreme example is at the start of the reward matrices chapter, where you change the reward matrix to have a weak nash against a Team blob and a strong nash against a Solo blob. you’re mostly using the top left quarter of the screen, with a bit of information in the top right, so the entire bottom half could be removed until we get to the part where we start making the 3x3 grid.

[@user-xl6yo6gf8e]

I thought D was correct, because we forgot that other blobs have an disadvantage if you are a solo blob. Being a solo blob will not help you directly but make life harder for other blobs. Therefore the chance for you to find a tree without anyone else being there and therefore gaining 2 fruits is higher. the Graph also seems to show that solo blobs lowly take over

[@Aazdremzul]

I think an interesting idea for this entire thing would be if each side had a mutation that could convince the opposing side. Teamwork can have the Diplomat (Purple), where if it encounters a Red it has a chance to convert it before getting fruits (3/4). Solo can have the Deviant (Orange), where if it encounters a Blue it has a chance to convert it after getting fruits (3/4). If the Diplomat meets a Deviant, they each have a (2/4) to convert the other to a blue or red respectively. A Diplomat and Deviant can only be born from a Blue or Red respectively with at least 5/4 fruit. This would be a way for each to propogate in a social way, because now they have a chance to effectively reproduce without needing to return home for offsprings. It'd show how upbringing and experience can propagate in an environment. The Diplomat represents a person that learned from the previous generation and the Deviant represents a person that continues teaching negative experiences.

[@kayodesalandy]

Technically that should end the very need of the game. Because what makes GT simulations of this kind interesting/relevant is that the 2 sides are unable to coordinate. Like the prisoners dilemma is only a dilemma because you don't know what your opponent is going to play. So assuming teamwork is objectively favourable, and the players are able to learn this, then the problem dissolves.

[@Aazdremzul]

@kayodesalandy That's fair, but I think the interactions and social elements in learning are really interesting to simulate. However, that's probably because I'm on a different wavelength here.

[@kayodesalandy]

@Aazdremzul oh I definitely agree! Like the more I think about it, what if we simulated it for a situation where selfishness was actually objectively better for the individual, but the diplomat can convince them otherwise? Of course the game gets exponentially more complicated because we need to simulate how selfish blobs interact with that proposition (endogenously determined by some factor/variable) to show that they are influenced by their physical environment. Funnily enough I'm not mathematically inclined, but game theory puzzles as word-logic games still appeal to me.

Because, acting violent can lead to shorter life spans (which could mean in this case a blob does not make through the day and reproduce).

One day I'd like to see predator blobs and prey blobs. It would be interesting. Have a good day

[@flamethrowex]

One thing I note in the simulation is that, regardless of how successful any given strategy is, the absolute maximum for overall population never changes, even if a strategy brings more mangos/energy "into" the population overall. As best as I can see, this is because success in one round doesn't carry over points to the next round, it just means more players on your team, and so more competing for the unchanging resource pool. I wonder if the results would change if the blobs were able to stockpile mangos when they have plenty, and/or were able to take mangos from annothers stockpile if it proved more promising than foraging directly from a tree

People that have been waiting one year for a new primer video 👇

[@catec4773]

I'm so glad to see this video, my moods terrible and I needed a pick me up. Thank you Primer!

[@thomasbelcher6921]

13:34 Pretty sure the solo blobs actually do have a tiny advantage because every time one meets another blob, that blob gets one less mango. This means it gets rid of its competition so it can carve out more of a niche for itself.

[@sharifkhudairi5368]

thats true, but it doesn't take into account that when 2 team blobs meet, both reproduce at a higher rate. So team vs solo, solo produces at a higher rate at the expense of team, but when its team vs team, both team reproduce at a higher rate (while only one solo benefits in the previous exchange).

Okay now simulate racism

[@ChingChong02946]

I vote *yes*

[@Cider8]

Yessir

[@LeoSinha-r6j]

I think it was techincally done with the green beard video

[@Kalaphant]

Just make it so that 10% of the blobs always fight 90% of them!

[@Greeen3Boi7]

Nah bro💀💀💀💀

[@Beatrix-VR]

It's always a good month when primer uploads.

[@snippykeegan]

I just love game theory and i love how you simplify the math with the simulations! i would love to learn how to do such a thing myself so i can play with the variables

[@sirnate9065]

These videos are so good. I love the format or the pace - how you gradually introduce complexity.

[@PrimerBlobs]

I'm streaming now on Twitch. Come by to chat about the video or anything else! www.twitch.tv/justin_helps

😂

[@lynnclaywood4043]

commenting for the algorithm boost!! love how easy it is to follow along these simulation vids!!

[@Maker0824]

I like how many times you've made a video on this same topic. This must be your favorite topic

[@GypsyCellist]

Hi Man U are rhit

[@GypsyCellist]

Hi

[@GypsyCellist]

Same I agree 0:54

[@The_Moth1]

I love how your profile picture is a happy blob’s face

[@tachyonites9568]

You know it's an educational eon when Primer uploads

[@michaelkindt3288]

@4:43-.-I'm guessing team blobs are going to dominate as a become more common.

[@tylerbuchanan2689]

I wish more people could see videos like this. I know many don't, but I thrive on basic theory like this. I do have my disagreements sometimes but they are variable based. Love your vids dude! Keep it going

[@purplecobra2090]

YES, YOUR NOT GONE! I was just checking your channel again yesterday to see if you uploaded again!

[@efjay3183]

07:40 The philosopher Thomas Hobbes referred to the nash equilibrium of both sides fighting the ”state of nature” and he argued that the most imortant aspect of a government, regardless of ideology or benevolence, is to ensure that the only nash equilibrium to exist for its people is to cooperate. He reviled the state of nature. They accomplish this through policing.

[@Hello21-tp1ez]

finally another primer vid is out, ive been waiting for this specific vid for a year

[@non-existantgamernop5172]

This is amazing, but a simulation like this doesn’t take into account consequences or any social response when choosing a selfish strategy. Still interesting to see and curious to know the outcome if you add two more stratergies to the mix. Like greed, they get the one fruit near the bottom of the tree but risk their life to get the two at the top and cautious, just taking one and leaving, only having a chance to get more with cooperation.

[@taylorhoganson6877]

Dude I was so excited to see a new Primer upload

[@taylorhoganson6877]

Update: did not disappoint at all. Awesome video!

I took a college course on this many years ago, but only the basics stuck... well that, and this same thing works at the allele level for genes. This provided much more insight.

Ура, новое видео! Судя по тому, что они выходят так редко, их сложно делать, удачи

[@robertfindley921]

If I had five employees: - One would work, on his/her assigned tasks, and provide status - One would work, on his/her assigned tasks, but refuse to provide status - One would refuse to work - One would work, but on an unassigned task unrelated to the project - One would complain all the tasks were wrong and should be redefined and re-assigned by him/her

[@danielsha7378]

Thanks for all the work you do!

[@maxk8425]

I know I am human because for every iteration in which teamwork was more effective, I found myself really rooting for them

[@JT-xb6zs]

I saw a similar test with a college team and they figured out the best strategy was to have a mutation where it copies the last person it came up against so it would copy somebody and be rude. If the other one was rude and then it would copy somebody was nice that was nice so it was always doing the last action that it was received, and that was the best strategy.

I like how this kind of thing mathematically proves why moral systems work the way they do

A more realistic version: - Two tribes - Same tribe, we work together - Different tribe, we fight

[@NE0KRATOS]

I love your videos, whenever a new one pops up I watch it immediately! I love game theory, and I love these animations. And the fact that you explore all the questions that pop up in my head is so satisfying! I feel this is the channel I would create if I had the knowledge of how to make these simulations!
