Lexicase Selection for Multi-task Evolutionary Robotics (2022, Artificial Life)
In this paper we tie together the early work on Lexicase for ER and push forward into searching for control parameters that deliver capability in multiple task types. We use Lexicase to drive the evolutionary process to optimise obstacle traversal, turn-to-target and cargo-carrying, rather than just obstacle traversal which was our single task. The paper demonstrates the potential of Lexicase to solve these kinds of problems.
Where do successful populations originate from? (2021, Journal of Theoretical Biology)
We explore the role of geographical factors such as land fertility and mountains in the context of human population evolution and distribution dynamics. We demonstrate though computational modelling and analysis of geographicsl data that successful human populations, i.e. those which become dominant in their environment, often originate from lands of many valleys with relatively low land fertility, which are close to areas of high land fertility.
