Computational Model Library

The simulation model LAMDA investigates the influences of varying cognitive abilities of the decision maker on the truth-inducing effect of the Groves mechanism. Bounded rationality concepts are represented by information states and learning models.

In CmLab we explore the implications of the phenomenon of Conservation of Money in a modern economy. This is one of a series of models exploring the dynamics of sustainable economics – PSoup, ModEco, EiLab, OamLab, MppLab, TpLab, CmLab.

John Q. Public (JQP): A Model of Political Judgment and Behavior

Sung-Youn Kim | Published Mon Mar 14 06:11:31 2011 | Last modified Sat Apr 27 20:18:37 2013

The model integrates major theories of political judgment and behavior within the classical cognitive paradigm embedded in the ACT-R cognitive architecture. It models preferences and beliefs of political candidates, parties, and groups.

This adaptation of the Relative Agreement model of opinion dynamics (Deffuant et al. 2002) extends the Meadows and Cliff (2012) implementation of this model in a manner that explores the effect of the network structure among the agents.

Simulation to replicate and extend an analytical model (Konrad & Skaperdas, 2010) of the provision of security as a collective good. We simulate bandits preying upon peasants in an anarchy condition.

Model of shifting cultivation. All parameters can be controlled by the user or the model can be run in adaptive mode, in which agents innovate and select parameters.

This model describes and analyses the Travel-Tour Case study.

Feedback Loop Example: Vegetation Patch Growth

James Millington | Published Thu Dec 20 19:02:47 2012 | Last modified Sat Apr 27 20:18:32 2013

This model illustrates a positive ‘growth’ feedback loop in which the areal extent of an entity increases through time.

SBH trust model

Di Wang | Published Tue Dec 14 14:50:47 2010 | Last modified Sat Apr 27 20:18:45 2013

This is a computational model to articulate the theory and test some assumption and axioms for the trust model and its relationship to SBH.

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
