Game of Thrones model (version 1.5.0)

This model slowly evolves to become Westeros, with houses fighting for the thrones, and whitewalkers trying to kill all living things. You can download each version to see the evolution of the code, from the Wolf Sheep Predation model to the Game of Thrones model. If you are only interested in the end product, simply download the latest version.

Release Notes

This is step 7 in the process of creating an ABM of Game of Thrones. It adds erratic season changes, snow, and whitewalkers. Patches north of the wall are now covered in snow, which makes them less productive. The model starts in summer, but as fall and the winter comes, the rate of grass regrowth slows down, which reduces the level of resources available. When winter comes, 10 whitewalkers appear north of the wall and start walking south. They kill every other living beings they encounter and create a new whitewalker in their stead. This step also introduces an nls file, which is used here to keep the whitewalkers’ procedures separate from the main code.
