Peer reviewed Umwelten Ants

Kit Martin | Published Thu Jan 15 16:19:41 2015 | Last modified Thu Aug 27 18:53:06 2015

Simulates impacts of ants killing colony mates when in conflict with another nest. The murder rate is adjustable, and the environmental change is variable. The colonies employ social learning so knowledge diffusion proceeds if interactions occur.

This is the code for the model described in an article in the International Journal of Microsimulation. Lawson (2013) ‘Modelling Household Spending Using a Random Assignment Scheme’, International Journal of Microsimulation, 6(2) Autumn 2013, 56-75.

A Modelling4All/NetLogo model of the Spanish Flu Pandemic

Ken Kahn | Published Mon Aug 5 15:17:09 2013 | Last modified Mon Aug 5 15:21:25 2013

A global model of the 1918-19 Influenza Pandemic. It can be run to match history or explore counterfactual questions about the influence of World War I on the dynamics of the epidemic. Explores two theories of the location of the initial infection.

Model of Context Switching with Segregation

Davide Nunes | Published Thu Aug 2 21:15:49 2012 | Last modified Sat Apr 27 20:18:39 2013

In the context switching model, a society of agents embedded in multiple social relations, engages in a simple abstract game: the consensus game. Each agent has to choose towards one of two possible choices which are basically arbitrary. The objective of the game is to reach a global consensus, but the particular choice that gets collectively selected is irrelevant.

Universal Darwinism in Dutch Greenhouses

An ABM, derived from a case study and a series of surveys with greenhouse growers in the Westland, Netherlands. Experiments using this model showshow that the greenhouse horticulture industry displays diversity, adaptive complexity and an uneven distribution, which all suggest that the industry is an evolving system.

Friendship Games Rev 1.0

David Dixon | Published Fri Oct 7 22:58:33 2011 | Last modified Sat Apr 27 20:18:32 2013

A friendship game is a kind of network game: a game theory model on a network. This is a NetLogo model of an agent-based adaptation of “‘Friendship-based’ Games” by PJ Lamberson. The agents reach an equilibrium that depends on the strategy played and the topology of the network.

Income and Expenditure

Tony Lawson | Published Thu Oct 6 13:52:24 2011 | Last modified Sat Apr 27 20:18:34 2013

How do households alter their spending patterns when they experience changes in income? This model answers this question using a random assignment scheme where spending patterns are copied from a household in the new income bracket.

A consumer-demand simulation for Smart Metering tariffs (Innovation Diffusion)

Martin Rixin | Published Thu Aug 18 10:29:34 2011 | Last modified Sat Apr 27 20:18:17 2013

An Agent-based model simulates consumer demand for Smart Metering tariffs. It utilizes the Bass Diffusion Model and Rogers´s adopter categories. Integration of empirical census microdata enables a validated socio-economic background for each consumer.

A Computational Model of Workers Protest

Jae-Woo Kim | Published Fri May 13 03:00:08 2011 | Last modified Sat Apr 27 20:18:17 2013

We present an agent-based model of worker protest informed by Epstein (2002). Workers have varying degrees of grievance depending on the difference between their wage and the average of their neighbors. They protest with probabilities proportional to grievance, but are inhibited by the risk of being arrested – which is determined by the ratio of coercive agents to probable rebels in the local area. We explore the effect of similarity perception on the dynamics of collective behavior. If […]
