Mesa: Agent-based modeling in Python 3+

Mesa is an Apache2 licensed agent-based modeling (or ABM) framework in Python.

Mesa allows users to quickly create agent-based models using built-in core components (such as spatial grids and agent schedulers) or customized implementations; visualize them using a browser-based interface; and analyze their results using Python's data analysis tools. Its goal is to be the Python 3-based counterpart to NetLogo, Repast, or MASON.

Above: A Mesa implementation of the Schelling segregation model, being visualized in a browser window and analyzed in a Jupyter notebook.

Features

• Modular components
• Browser-based visualization
• Built-in tools for analysis

Using Mesa

Getting started quickly:

$ pip install mesa

To launch an example model, clone the repository folder and invoke mesa runserver for one of the examples/ subdirectories:

$ mesa runserver examples/wolf_sheep
