I'm currently working on:
CEDSS, an agent-based model of domestic energy demand at household and community level.
ROFS, an agent-based model of Roman military communications on Hadrian's Wall. Modelling of human-environmental and socio-technical systems.
Celluar automata, specifically Conway's "Game of Life".
For publications, see nickgotts.weebly.com/publications.html. I will upload some shortly.
