A Model of Iterated Ultimatum game

Andrea Scalco | Published Tue Feb 24 16:08:20 2015 | Last modified Mon Mar 9 16:13:23 2015

The simulation generates two kinds of agents, whose proposals are generated accordingly to their selfish or selfless behaviour. Then, agents compete in order to increase their portfolio playing the ultimatum game with a random-stranger matching.

Human mate choice is a complex system

A general model of human mate choice in which agents are localized in space, interact with close neighbors, and tend to range either near or far. At the individual level, our model uses two oft-used but incompletely understood decision rules: one based on preferences for similar partners, the other for maximally attractive partners.

Forager mobility and interaction

This is a relatively simple foraging-radius model, as described first by Robert Kelly, that allows one to quantify the effect of increased logistical mobility (as represented by increased effective foraging radius, r_e) on the likelihood that 2 randomly placed central place foragers will encounter one another within 5000 time steps.

Communication and social change in space and time

Sebastian Kluesener Francesco Scalone Martin Dribe | Published Tue May 17 10:30:29 2016 | Last modified Fri Oct 13 16:24:43 2017

This agent-based model simulates the diffusion of a social change process stratified by social class in space and time which is solely driven social and spatial variation in communication links.

Landscape connectivity and predator–prey population dynamics

Jacopo Baggio | Published Thu Nov 10 19:35:38 2011 | Last modified Sat Apr 27 20:18:37 2013

A simple model to assess the effect of connectivity on interacting species (i.e. predator-prey type)

Positive feedback can lead to “trapping” in local optima. Adding a simple negative feedback effect, based on ant behaviour, prevents this trapping

A modified model of breeding synchrony in colonial birds

James Millington | Published Tue Jun 26 14:20:05 2012 | Last modified Sat Apr 27 20:18:19 2013

This generic individual-based model of a bird colony shows how the influence neighbour’s stress levels synchronize the laying date of neighbours and also of large colonies. The model has been used to demonstrate how this form of simulation model can be recognised as being ‘event-driven’, retaining a history in the patterns produced via simulated events and interactions.

Coupled Housing and Land Markets (CHALMS)

Nicholas Magliocca Virginia Mcconnell Margaret Walls | Published Fri Nov 2 20:20:30 2012 | Last modified Mon Oct 27 16:23:37 2014

CHALMS simulates housing and land market interactions between housing consumers, developers, and farmers in a growing ex-urban area.

Gunpowder battle tactics

Xavier Rubio-Campillo Jose María Cela Francesc Xavier Hernàndez | Published Wed Nov 20 13:14:07 2013 | Last modified Tue Nov 26 11:34:21 2013

This model simulates the dynamics of eighteenth-century infantry battle tactics. The goal is to explore the effect of different tactics and individual traits in the dynamics of the combat.

Adoption as a social marker

A model of innovation diffusion in a structured population with two groups who are averse to adopting a produce popular with the outgroup.
