This is a replication model of the matching problem including the mate search problem, which is the generalization of a traditional optimization problem.

This model is a replication of that described by Peterson (2002) and illustrates the ‘spread’ feedback loop type described in Millington (2013).

This model illustrates a positive ‘transport’ feedback loop in which lines with different resistance to flows of material result in variation in rates of change in linked entities.

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

A reimplementation of the Wedding Ring model by Francesco Billari. We investigate partnership formation in an agent-based framework, and combine this with statistical demographic projections using real empirical data.

DIAL is a model of group dynamics and opinion dynamics. It features dialogues, in which agents put their reputation at stake. Intra-group radicalisation of opinions appears to be an emergent phenomenon.

Agents co-operate or defect towards other agents in a prisoner’s dilemma, with strategy choice depending on whether agents share tags or are kin in different social structures.

This is a replication of the altruistic trait selection model described in Pepper & Smuts (2000, 2002).

NetLogo implementation of Linear Threshold model of influence propagation.

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