This is an agent-based simulation chemical diffusion in the environment.

Cells representing the Environment can hold the chemical being disbursed. Each timestep this chemical is reduced in each cell through diffusion and evaporation.

To install the dependencies use pip and the requirements.txt in this directory. e.g.

    $ pip install -r requirements.txt

To run the model interactively, run mesa runserver in this directory. e.g.

    $ mesa runserver

Then open your browser to http://127.0.0.1:8521/ and press Start.

There are many parameters that can be adjusted to explore different disbursement patterns.

• Evaporation Rate: the percentage of chemical that disappears each step.
• Diffusion Rate: the percentage of chemical that is disbursed to surrounding cells each step.
• Initial Drop: the amount of chemical dropped at the start of the simulation.

Based on diffusion in the original NetLogo Ants model:
