This model aims to examine how different levels of communication noise and superiority bias affect team performance when solving problems collectively. We used a networked agent-based model of collective problem solving in which agents explore the NK landscape for a better solution and communicate with each other regarding their current solutions. We compared the team performance in solving problems collectively at different levels of self-superiority bias when facing simple and complex problems. Additionally, we addressed the effect of different levels of communication noise on the team’s outcome

This model is to explore how individuals’ cultural backgrounds may play a role in their Covid vaccination decision-making. Two cultural dimensions of collectivism/individualism and power distance are considered. Through the experimental scenarios, we find that Covid-vaccination opinions in collectivist societies can also be considerably polarised, if the power distance is less and authorities less centralised. This result complements the popular idea that cultural collectivism is usually associated with a high degree of social consensus. Hopefully, this study will help explain countries’ difference in the response of Covid vaccination programs.

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

The network-based trust game is a hybridization of both the repeated trust games and the network games.

Scilab version of an agent-based model of societal well-being, based on the factors of: overvaluation of conspicuous prosperity; tradeoff rate between inconspicuous/conspicuous well-being factors; turnover probability; and individual variation.

This model simulates how collective self-organisation among individuals that manage irrigation resource collectively.

A hybrid predator-prey model of fish and plankton that switches dynamically between ABM and SD representations. It contains 6 related structural designs of the same model.

This is an agent-based model designed to explore the evolution of cooperation under changes in resources availability for a given population

The NetLogo model implements an Opinion Dynamics model with different confidence distributions, inspired by the Bounded Confidence model presented by Hegselmann and Krause in 2002. Hegselmann and Krause used a model with uniform distribution of confidence, but one could imagine agents that are more confident in their own opinions than others. Confidence with triangular, semi-circular, and Gaussian distributions are implemented. Moreover, network structure is optional and can be taken into account in the agent’s confidence such that agents assign less confidence the further away from them other agents are.

The purpose of this model is explore how “friend-of-friend” link recommendations, which are commonly used on social networking sites, impact online social network structure. Specifically, this model generates online social networks, by connecting individuals based upon varying proportions of a) connections from the real world and b) link recommendations. Links formed by recommendation mimic mutual connection, or friend-of-friend algorithms. Generated networks can then be analyzed, by the included scripts, to assess the influence that different proportions of link recommendations have on network properties, specifically: clustering, modularity, path length, eccentricity, diameter, and degree distribution.
