The model is an extension of Epstein's civil violence model. Similar to Lemos et al. We broaden Epstein's Model with a delay in time before agents are imprisoned, representing the fighting time prior to an arrest and a feedback mechanism that allows the legitimacy to vary as a function of the number of arrests and violent episodes. The purpose of the model is to introduce a network representing social media contacts in the extended version of the ABM of civil violence of Epstein.

This repository contains 2 models, one model with a network which is in the epstein_civil_violence_Normal+Network Grid folder and one model without a network, which can be found in the epstein_civil_violence_NormalGrid folder. To run the model one must first choose which model he/she wants to run.

The model can then be played by executing: run.py

    $ python run.py

Then open your browser to https://127.0.0.1:8521/ and press Reset, then Run.

This shows how the agents move in the grid as shown above. The red dots represent the active citizens, the green dots the fighting citizens and the blue dots the quiscent citizens. The small black dots are the cops.

The data from the model can be retrieved by executing: model_run.py

    $ python model_run.py

This will run the model for 200 iterations and returns a graph of the state of the citizens over time, a graph of the perceived legitimacy over time and features for analysing the results.

A more elaborate view of this model can be found in the paper: Project: An Agent-based Model of Civil Violence by Buranelli et al.
