WHAT IS IT?
A version of SugarScape, as presented in "Growing Artificial Societies" by Epstein and Axtell. It builds on Owen Densmore's NetLogo community model to encompass all rules discussed in GAS with the exception of the combat rule (although trivial to include, it adds little value to the model).
HOW IT WORKS
Patches represent a toroidal world with "sugar" (representing wealth) deposited in two roughly circular regons or "hills" of increasing sugar density. Agents and patches follow a number of rules designed to deomonstrate various properties that emerge from this simple artificial society.
HOW TO USE IT
The chooser labelled "Presets" offers a variety of settings to explore the scope of the Sugarscape. To set model parameters to the presets, click "Setup Preset".
THINGS TO TRY
The Sugarscape can be home to a colourful variety of emergant structure and behavior. How to use the interface, and information on the different presets, and effects that can be seen are discussed more in a document which can be found here:
EXTENDING THE MODEL
This version of Sugarscape has been very successful in achieving the same results as those presented in GAS. However, several observations have not been successfully recreated, and it is unclear how GAS implimented some combinations of rules, such as L in the two resources landscape.
Discrepancies are discussed more thoroughly here:
