This paper proposes two models for simulating belief update in social networks in cases where certain beliefs might be considered to be competing. The proposed models represent different attitudes of people towards the perceived conflict between beliefs. Computer simulations show that the first model usually divides the community into several distinct(More)

This paper analyzes two proposed models for simulating opinion dynamics in social networks where beliefs might be considered to be competing. In both models agents have a degree of tolerance, which represents the extent to which the agent takes into account the differing beliefs of other agents, and a degree of conflict, which represents the extent to which(More)
A single predator, single prey ecological model, in which the behaviour of the populations is reliant upon two control parameters has been expanded to allow for multiple predators and prey to occupy the ecosystem. A focus has been placed on analysing the diversity of the ecosystem that develops as the model runs, assessing how many predator or prey species(More)
