Short summary
This paper reviews existing wildfire propagation models and a comparison of different grid types including random grids to simulate wildfires. This paper finds that grids can simulate wildfires more efficiently than continuous models while still retaining a reasonable level of similarity. It also shows that an irregular grid called the flammable resolution grid tends to retain greater similarity to continuous models than regular grids at the cost of slightly longer computational times.
