This model extends the bounded confidence model of Deffuant and Weisbuch. It introduces online contexts in which a person can deliver his or her opinion to several other persons. There are 2 additional parameters accessibility and connectivity.

A Simulation of Entrepreneurial Spawning

Mark Bagley | Published Wed Jun 8 19:33:28 2016 | Last modified Fri Jun 30 11:01:46 2017

Industrial clustering patterns are the result of an entrepreneurial process where spinoffs inherit the ideas and attributes of their parent firms. This computational model maps these patterns using abstract methodologies.

Effect of communication in irrigation games

Marco Janssen Jacopo Baggio | Published Wed Jan 14 04:08:32 2015 | Last modified Wed Aug 9 01:28:22 2017

The model includes different formulations how agents make decisions in irrigation games and this is compared with empirical data. The aim is to test different theoretical models, especially explaining effect of communication.

Opinion Dynamics Under Intergroup Conflict Escalation

Meysam Alizadeh Alin Coman Michael Lewis Katia Sycara | Published Fri Mar 14 22:12:37 2014 | Last modified Wed Oct 29 18:13:27 2014

We develop an agent-based model to explore the effect of perceived intergroup conflict escalation on the number of extremists. The proposed model builds on the 2D bounded confidence model proposed by Huet et al (2008).

Shared Norms and the Evolution of Ethnic Markers

Nathan Rollins | Published Fri Jan 22 17:35:22 2010 | Last modified Sat Apr 27 20:18:45 2013

The publication and mathematical model upon which this ABM is based shows one mechanism that can lead to stable behavioral and cultural traits between groups.

Vulnerability of Cooperation Due to Limited Vision

Marco Janssen | Published Thu Dec 2 23:00:56 2010 | Last modified Sat Apr 27 20:18:53 2013

This model describes the consequences of limited vision of agents in harvesting a common resource. We show the vulnerability of cooperation due to reduced visibility of the resource and other agents.

cultural group and persistent parochialism

Jae-Woo Kim | Published Mon Nov 8 06:23:12 2010 | Last modified Sat Apr 27 20:18:28 2013

Discriminators who have limited tolerance for helping dissimilar others are necessary for the evolution of costly cooperation in a one-shot Prisoner’s Dilemma. Existing research reports that trust in

Agent-Based Computational Model of the cryptocurrency Bitcoin with a realistic market and transaction system. Bitcoin’s transaction limit (i.e. block size) and Bitcoin generation can be calibrated and optimized for wealth and network’s hashing power by the Non-Dominated Sorted Genetic Algorithm - II.

Model to assess factors that influence local communities compliance with protected areas policies

Gustavo Andrade | Published Mon Nov 21 05:50:54 2011 | Last modified Sat Apr 27 20:18:40 2013

We built a model using R,polr package, to assess 55 published case studies from developing countries to determine what factors influence the level of compliance of local communities with protected area regulations.

Active Shooter: An Agent-Based Model of Unarmed Resistance

Thomas W Briggs William Kennedy | Published Thu Dec 29 22:38:58 2016 | Last modified Tue Apr 4 20:57:15 2017

A NetLogo ABM developed to explore unarmed resistance to an active shooter. The landscape is a generalized open outdoor area. Parameters enable the user to set shooter armament and control for assumptions with regard to shooter accuracy.
