The Emergence of Cooperation

[Sibarit1973]

is this PS-1 you are using for simulation?

[De4sher]

so you're saying that ice cream evolved from monkeys?

[icellily]

oh... pretty colors... What the freak is this?

[orcodrilo]

It wouldn't hurt to say what are the rules goals, or system that follows this model....

Otherwise those are just colored dots on the screen.

[VictorPhillip]

@orcodrilo right

Ahh! My brain!

[fileeinstein]

For details and related videos, just google with the key words "Helbing" and "Simulations".

[metalicrobot66]

I dont understand this AT ALL!

[chewy0tang]

what are the underlying rules for this simulation? Is there the assumption that cooperator interaction always lead to greater payoff? Very interesting. How might this model change if you introduce deceptive cooperators (ie defectors that act as cooperators)? Can you think of a model for the current economic crisis? Heh.

[NewColdness]

It's probably a classic Prisoner's Dilemma, with the cooperation strategy being strictly dominated by the defection strategy, and with the sum of the payoff of mutual cooperation to both players being greater than a defector's gain minus a cooperator's loss.

'course, that's just a guess.

what happens with further iteration ?

[LogicRising]

they become conscious and take over the world.

[fileeinstein]

The overcritical cluster of cooperators (blue) does not only allow cooperators to survive; neighboring defectors also start to imitate them due to their greater payoff (green). The evolution in Phase III is shown again at the previous movie speed: Once a large enough cooperative cluster has appeared, cooperation is "exported" to other locations by random and success-driven migration, and it spreads quickly among individuals almost everywhere.

[fileeinstein]

Phase II is displayed more slowly to highlight the sudden outbreak of cooperation: Around the time t=25,510, a small, but overcritical cluster of cooperators appears in the upper right corner (green and blue). This happens by random coincidence of strategy mutations, which creates cooperators in neighboring locations by chance.

[fileeinstein]

Nevertheless, small defective clusters are formed, as the payoff for mutual defection is higher than when defectors do not have any neighbors. Cooperators are generated randomly at a very small rate due to strategy mutations (green), but usually turn into defectors quickly (yellow). The video is cut, because the features of the spatio-temporal patterns do not change over more than 20,000 iterations.

[fileeinstein]

The simulation starts with the initial configuration of a circular cluster of defectors (red) at time t=0. In each time step (iteration), the strategies and locations of all individuals have been updated in a random sequential order. The video shows one snapshot every time step. In Phase I, the cluster of defector splits up, and defectors disperse over the space due to random relocations.

[fileeinstein]

Spontaneous outbreak of prevalent cooperation in the spatial prisoner's dilemma with random relocations and strategy mutations. The prisoner's dilemma describes social interactions, in which it is risky to cooperate and tempting to defect (i.e. to cheat or free-ride).

The simulations are for 49x49-grids (red = defector, blue = cooperator, white = empty site, green = defector who became a cooperator, yellow = cooperator who turned into a defector in the last iteration).

What is this?

[Rikotistic]

I need to source this in my book. I wonder if such an outbreak of cooperation is part of an ongoing feature of human evolution. I rather think we cooperated sparsely the first 190,000 years of our time as Homo sapiens.

richard pascales concpet of Complex adaptive systems....this is a good wya to explain that

[danierusama]

this looks like cells under a microscope
