Model

A simple agent-based model on a toroidal grid

To run the model, just clone and run python3 foraging/model_viz.py

Plants are fixed, and reproduce asexually by making offshoots. Every turn they grow until they are fully grown and eatable by rabbits

For a plant to reproduc :

An cutting must fall on the ground in the neighbourhood of the plant with a fixed probability (r)
The cutting will then have a lower chance of survival if there is already one plant or more growing nearby
The cutting must be place in appropriate conditions (currently : not in water it's a land plant)

Every turn, rabbits must :

Moving one case is pretty straightforward : they just move randomly Rabbits must eat a carrot every turn :

If a rabbit hasn't been eating carrots for five turns, they die
If a rabbit is on the same case as a fully grown plant, they can gain a carrot
If a rabbit has more than a fixed number of carrot, they can give the carrot to a rabbit on the same case
Rabbit can accumulate carrots and keep the carrots with them Every turn, rabbits can also reproduce :
If they are on the same case as another rabbit of the opposite sex, they can create a new rabbit with a fixed probability

Every turn Foxes must :

They are mostly similars to rabbit with a few differences :

They are less likely to reproduce in any given encounter with an opposite sex fox
They can't accumulate rabbits the way rabbits accumulate carrots
Nevertheless, they can spend more turn without eating, and starve much less frequently

The interface should look like that :

With the right parameters, populations should start stabilizing :
