Agents.jl: Wishlist for more famous systems in Examples

[yuxiliu1995]

• [ ] Hexagonal grids like SIRS and game of life.
• [ ] B-Z reaction and other reaction-diffusion systems
• [x] [Diffusion-limited aggregation](https://www.complexity-explorables.org/explorables/particularly-stuck/)

More examples can be collected here.

Hm, the second one is a system governed by partial differential equations, which is not a good case to model with ABMs... The other two are cool though!

Agent_Zero contains a lot of agent-based models.

The Bonabeau model for hierarchy-formation. This paper in particular has some really curious bifurcation diagrams.

Mesa has also a great pool of examples here: https://github.com/projectmesa/mesa/tree/master/examples and we could port some.

• [x] I'll try coding up the sheep wolf example listed in the Mesa respo. I should have time to work on it during the weekends.

We're doing a lot of these with DiffEqBiological, since indeed moving between and with the differential equation solver is kind of essential. But maybe there could be a nice package to tie the two together to build these reaction-diffusion master equation (RDME) models. I'll keep this in mind.

• [x] Daisyworld https://en.wikipedia.org/wiki/Daisyworld

[Datseris]

The HASH platform has several examples that we can put here as well: https://hash.ai/index/search?contentType=Simulation&page=1

e.g.

• [ ] Supply chain
• [ ] Prisoner's dilemma
• [x] Epstein civil unrest
• [ ] Breeding synchrony

among others

This rainfall one from HASH is something we could definitely take a look into. It has a simulated 3D terrain, which is still just a heightmap on 2D, but could be a good example of how to introduce geometry into our spaces.

[Datseris]

Would be nice to have a truly 3D example, like 3D continuous space or 3D grid space, that we can then also use in the interactive application.

https://www.complexity-explorables.org/explorables/particularly-stuck/ (The third one by @yuxiliu1995) seems interesting. I'll implement this

[AayushSabharwal]

I have some initial work in https://github.com/JuliaDynamics/Agents.jl/pull/384

[Datseris]

Just came across this: https://www.sciencedirect.com/science/article/pii/S0304380096019424 which is related with forest fire models.

This has three pretty interesting simulations. With the current setup it may not be possible to make the same visualisations, but it's interesting nonetheless.

That slime mould is spectacular. I don't think it's outside of our plotting capabilities actually. It'll be a big simulation though.
