Dear Michael Tamillow - If you don't have any advice or an answer to a question, then please refrain from posting things that are unwelcoming or can be interpreted as aggressive, especially that you mostly posted your own opinion and not some empirical evidence that your view is correct.

Your email is relevant and timely to me - Anarchy surely in the news and social media these days. As it happens, I am deep in a rathole of research this weekend around Anarchy, governance, and decentralized command and control and governance of coalition command structures.
Your question
" is there an Anarchy model already done in Netlogo"
My answer depends on your definition of Anarchy. Here's a few definitions that I would try when relating to a Netlogo Model.
definition 1
answer: Many Netlogo models (flocking, fluid dynamics/convection, crowd dynamics, ising models, etc) have phases where the system is disordered depending on the parameter settings. Sweeping your parameters with BehaviorSpace lets you sample the "phase space" of the model. You can measure the disorder of the phase with an entropy metric observing the probability of the agents occupying their available states. (see equipartition theorem) A model in a phase with high entropy could be said to be in a State of Anarchy or State of Chaos. As an aside, I tend to use Chaos more technically (sensitive to initial conditions) and the model is chaotic at the phase transitions or critical points instead of describing the model as being chaotic when it is in the unordered phase. I would avoid the vernacular use of Anarchy but it will require you to also define your term technically.
answer: Many of the same canonical complex systems models in Netlogo demonstrate leaderless organization. Traffiic jams, flocking, ant foraging etc. Here, we could say the model is a model of Anarchy regardless of the phase that the model is in. It's more about the logic of the model where organization emerges through the interactions of the agents and not designed in with prescribed hierarchy.
definition 3:
Voluntary association and cooperation. Rejecting subjugation through violence, force, or other coercion.
answer: If requests to change state between agents is done with the ASK and the agent has context-sensitive rules on executing the command, I would say that model has an Anarchist governance model. Somewhere around Netlogo ver 3 or 4, the preferred pattern was to use ASK. Prior to this, the pattern was agents would directly change the state of another agent. commanded with no choice. That is now considered bad form in ABM and not adhering to the Anarchist Cookbook :-) This is also along the lines of Pattie Maes clever definition: "an agent is a software object that can say no". In my research right now with emergency management and Defense, I am thinking about how a firefighter in a in an incident command team hierarchy with command and control, are encouraged to refuse orders for many context-sensitive reasons. I would call incident command in wildfire Anarchical under this definition. https://www.nwcg.gov/committee/6mfs/refusing-risk.Contrast that with the military where a soldier can only refuse an order if its illegal. There is related ideas with respect to Mission vs Detailed Command and Control where the former is decentralized and the latter centralized.
definition 4: Rejection of the State as Authority.
answer: A Netlogo model would be Anarchic if the agents exercising authority, emergent or explicit were labeled as such. So imagine having different agents of legal status (State, Corporation, Natural Person) and then calling the model Anarchic if the State was not involved in the authority hierarchy. This is the least interesting example to me.
Hope that helps. As I am not a domain expert in Anarchism in its different forms or even Political Science in general, I would welcome any feedback as I am working on a paper around this.

I agree with the others that, whether you intended it or not, the tone of your response came off as aggressive and condescending.
The tone of this: "What does that even mean?" Implies, "how can you ask such a stupid and meaningless question?"
And then the rest of your reply was about your personal beliefs around the political viability and meaning of anarchy, which doesn't contribute to an answer about models of anarchy but seems to project to the questioner, "you're ignorant to ask about this since it all means nothing and what your asking about amounts to nothing"
And this, "Define your modeling assumptions before beginning.", with no context, is maybe good advice, but following the rest of your reply comes off as condescending and dismissive.
Now I'm not saying you intended your response to be received this way, but that's how some of us here are receiving it. If you didn't intend that, it might be worth looking into the importance of tone in communication. It's especially important in written communication since the normal visual and audio cues are missing so it's easy to come off as aggressive when you don't actually intend it.
As for the question, yes, there are models and efforts around anarchy in agent based modeling. For example, here's this write up of using ABM to study organizational anarchy: https://pubsonline.informs.org/do/10.1287/orms.2008.04.12/full/
And if you think of "anarchy" as a kind of self-organization, without direction from kind of top-down ruler/organizer, then the concept of anarchy is fundamental to many ideas in agent based modeling. The classic "ants" model (see the Model Library in NetLogo) provides a nice illustration of how a few basic rules of individual behavior applied to a population leads to a behavior that appears very organized, as if directed from a central authority.

Hi Paolo,
Thanks for your interest in NetLogo modeling.
For item 1) if you want the maximum x value on a plot using auto-scaling to be an integer, you can edit the plot and put the line
set-plot-x-range plot-x-min ceiling plot-x-max
in the Plot update commands section.
Y values can be controlled in similar fashion.
As far as item 2) is concerned NetLogo provides only a basic plotting capability with the assumption that users can use other programs with their data to produce more sophisticated plots. You have made good case for how some features would be helpful to new users. However I don’t think such enhancements will be available in the near future.
Here is one way to make tick-like marks every 10 ticks
edit the plot
Add a new pen
Change the color if desired by clicking on the color square, selecting a color from the palette that opens and clicking OK
put the following line in the pen’s Plot update commands section section:
if ticks mod 10 = 0 [ plot-pen-up plotxy ticks 0 plot-pen-down plotxy ticks plot-y-max / 50 ]
You can adjust the spacing and height of the “ticks” by changing the numbers 10 and 50.
This code is based on https://stackoverflow.com/questions/20988126/how-to-plot-a-vertical-line-every-x-step-in-netlogo by Stephen Guerin
One explanation for why the minimum and maximum values numbers are offset from their actual locations is that the lowest coordinates on the y and y axes would otherwise collide (given the layout), and that the maximum values are similarly constrained to lie within the physical plot range.
I hope this is helpful, and let the list know if you have further questions.
Aaron
