Model zoo (in Netlogo) for the book Spatial Simulation: Exploring Pattern and Process.
This is the collection of Netlogo models we built for our book Spatial Simulation: Exploring Pattern and Process. The models are also available at the book website.
The purpose of putting the models here, is to speed up the process of adequately commenting them, and also to make it easier to make minor tweaks and corrections to the code.
The models as originally released when the book appeared (and as used to generate the figures in the book) are in the folder as-released. These will not change, and will not be updated to remain compatible with later versions of NetLogo. They were written for NetLogo 5.0.x. They will likely work with other NetLogo 5.x versions, but you will need to have the necessary extensions installed. If opened in later versions of NetLogo, the automated translation provided may work, but it might not. This folder is split into a base-models folder which should not need any extensions and a using-R folder which requires the r extension.
Models are being kept up to date, to add more information about how they work and additional in-code comments, and for compatibility with newer versions of NetLogo, most recently 7.0.0. The latest versions of the models are in the top level base-models folder. Some models require the SimpleR extension.
A frozen release of these folders compatible with NetLogo 5.3 was created on 18 November, 2017: v0.5.3 release
A final release compatible with NetLogo 6.4.x was created on 2 August, 2024: v0.6.4 release.
An initial release compatible with NetLogo 7.0.0 was created on 22 September 2025: v0.7.0 release.
The most current code in base-models and using-R folders aims to be compatible with current recent versions of NetLogo.
Models in base-models and using-R should all work with NetLogo 7.0.x. They will not work in earlier versions as there has been a change in NetLogo file formats. Models in as-released and misc may not.
