Mobility, Resource Harvesting and Robustness of Social-Ecological Systems

Irene Perez Ibarra | Published Mon Sep 24 16:41:20 2012 | Last modified Sat Apr 27 20:18:39 2013

The model is a stylized representation of a social-ecological system of agents moving and harvesting a renewable resource. The purpose is to analyze how mobility affects sustainability. Experiments changing agents’ mobility, landscape and information governments have can be run.

Agent-Based Model for the Evolution of Ethnocentrism

Max Hartshorn | Published Sat Mar 24 21:34:18 2012 | Last modified Sat Apr 27 20:18:21 2013

This is an implementation of an agent based model for the evolution of ethnocentrism. While based off a model published by Hammond and Axelrod (2006), the code has been modified to allow for a more fine-grained analysis of evolutionary dynamics.

Varying effects of connectivity and dispersal on interacting species dynamics

Kehinde Salau | Published Mon Aug 29 08:01:17 2011 | Last modified Sat Apr 27 20:18:53 2013

An agent-based model of species interaction on fragmented landscape is developed to address the question, how do population levels of predators and prey react with respect to changes in the patch connectivity as well as changes in the sharpness of threshold dispersal?

Replication of ECEC model: Environmental Feedback and the Evolution of Cooperation

Population Control

David Shanafelt | Published Mon Dec 13 15:53:14 2010 | Last modified Sat Apr 27 20:18:43 2013

This model looks at the effects of a “control” on agent populations. Much like farmers spraying pesticides/herbicides to manage pest populations, the user sets a control management regiment to be use

The role of spatial foresight in models of hominin dispersal

Colin Wren | Published Mon Feb 24 20:36:57 2014 | Last modified Mon Jul 14 13:31:31 2014

The natural selection of foresight, an accuracy at assess the environment, under degrees of environmental heterogeneity. The model is designed to connect local scale mobility, from foraging, with the global scale phenomenon of population dispersal.

The model explores the emergence of inequality in cognitive and socio-emotional skills at the societal level within and across generations that results from differences in parental investment behavior during childhood and adolescence.

Local scale mobility, namely foraging, leads to global population dispersal. Agents acquire information about their environment in two ways, one individual and one social. See also http://www.openabm.org/model/3846/

Evolution of cooperative strategies from first principles

Marco Janssen | Published Mon Jan 4 22:49:23 2010 | Last modified Sat Apr 27 20:18:30 2013

The purpose of this model is to study the evolution of cooperation when agents are endowed with a limited set of receptors, a set of elementary actions and a neural network agents use to make decision
