In a rectangular world, there are cells and three types of agents: Fire, tree, and burnt tree. Initially, and each time the model is reset, the world is created. A fire starts in random cell. The fire spreads and feeds off the trees it attaches to and spread further. At no point during the simulation can two agents occupy the same cell. The state of the model is initially drawn on the screen.
During each time step of the simulation,
The simulation runs indefinitely, until the stop button is clicked.
