Diffuse Model

A simple model of pheromone diffusion by ants. This simple model presents ants that move randomly in a radius of 2 space units and deposits pheromones on the ground. The pheromones diffuse on the space and evaporate simultaneously.

There is 2 kinds of entities:

  • Ants who deposite hormones on the ground while moving randomly, and
  • Cell, in charge of storing hormone (#qty attribute), diffusing it and evaporating it

Standard version​

Diffusion of pheromones (evaporation and synchronous diffusion), then activities of the ants. In the standard version stepSynchronously, the ants move randomly in a radius of 2 cells.

Jumping version​

In the jumping version stepSynchronouslyJump, the ant moves randomly (radius of 2 cells) and deposits pheromone. But if the hormone qty is too elevated, it jumps randomly.

Run the model in Cormas​

  1. Load the model
  2. Prepare the simulation:
  • init method = init (4 neighbours)
  • step method = stepSynchronously (or stepSynchronouslyJump)
  • click on the Reinitialize simulation button, then
  • click on the Run button
