A very simple standalone ABM example in Julia that can be used as a starting point for a new ABM implementation.

All model-specific code is contained in lower-case .jl files. All other files contain modules that are more or less general and can be reused.

The main parts of the model:

• setup_world.jl functions to create the world in different configurations
• model.jl data structures and processes that make up the model itself
• analysis.jl observations and data output
• setup.jl create a runnable model
• params.jl model parameters
• draw_gui.jl draw the model to a canvas
• run_gui.jl ties everything together, creates model from commandline parameters and runs it with GUI
• run_cmdl.jl ties everything together, creates model from commandline parameters and runs without gui

In order to implement a new model only a few of the included files have to be changed:

• model.jl for the model itself
• setup.jl for model-specific setup and initialisation
• params.jl to define model parameters
• analysis.jl for output

And for the GUI version:

• draw_gui.jl to display the model
• run_gui.jl for model-specific graphs

Run as julia run_gui.jl or julia run_cmdl.jl. Run with --help to see commandline options.

draw_vector.jl contains currently unused code to draw the world as an SVG image using Luxor.

In order to run the model the following packages have to be installed:

• MiniEvents (not registered yet, for now install as add https://github.com/mhinsch/MiniEvents.jl)
• MiniObserve (not registered yet, for now install as add https://github.com/mhinsch/MiniObserve.jl)
• DataStructures
• Distributions
• ArgParse
• Parameters
• MacroTools
• StaticArrays
• SimpleDirectMediaLayer (for GUI only)
