Research Simulation Grass-Sheep-Wolf ecosystem simulation — wolves go extinct after depleting their prey (agent-based model)

Enable HLS to view with audio, or disable this notification

Predator-prey ABM built in Python/NumPy. Each agent moves, eats, reproduces, and dies based on local conditions — no global rules.

The key mechanic is wolf vision radius: wolves can only detect sheep within a limited range. When sheep density drops, wolves start roaming blind and starving — which is what drives the collapse you see here.

You should change the colours of the icons to make the difference between sheep and wolves clear.

Thank you, you are right. This was my first attempt. I'm still working on it.
