This presentation was given at UCT's Open Data Day on 6th March 2020. The presentation outlines the utility of repeat photography in understanding changing landscapes, through citizen science. Historical landscape photographs are scientifically valuable evidence of what landscapes looked like in the past and can be a useful source of biodiversity data in otherwise data-deficient geographic regions. Acquiring repeats of historical photographs on broad geographic scales is possible through rePhotoSA, a collaborative citizen science project led by the Plant Conservation Unit and the FitzPatrick Institute at UCT, which hosts an open online repository of historical landscape images.

The R code explores the calibration and simulation of the Farmer and Joshi (2002) agent-based model of financial markets using the method of moments along with a genetic algorithm and a Nelder-Mead with threshold accepting algorithm. The model is used for understanding daily trading decisions made from closing auction to closing auction in equity markets, as it attempts to model financial market behaviour without the inclusion of agent adaptation. However, our attempt at calibrating the model has limited success in replicating important stylized facts observed in financial markets, similar to what has been found in other calibration experiments of the model. This leads us to extend the Farmer-Joshi model to include agent adaptation using a Brock-Hommes (1998) approach to strategy fitness based on trading strategy profitability. The adaptive Farmer-Joshi model allows trading agents to switch between strategies, favouring strategies that have been more profitable over some period of time determined by a free-parameter determining the profit monitoring time-horizon.
