About

Agent-based models have been used in ecological settings to study phenomenon such as adaptation to environmental change, in social settings to model artificial societies as well as in economic settings to model such things as the strategies available in different types of networks. COBWEB allows simulation of genetic change, ecological change, economic location, the Prisoner’s Dilemma, adaptation to environmental change, vector-borne disease and heatwaves. It was the brain child of Dr. Brad Bass and currently plays a large role in his university research as well as high school education programs at the University of Toronto.
