Efficiently classifying shocks in complex systems requires dormant reporters
David A. Brewster, Philippe Cluzel
Many natural and engineered systems are large complex networks of interacting components, and external perturbations drive them along different dynamical paths. Identifying which p…
Fixation location in structured populations
David A. Brewster, Gabor Lippner, Josef Tkadlec +1
In stochastic evolutionary dynamics, the replacement of an existing genotype or cultural trait by a newly introduced mutant is typically characterized by the quantities of fixation…
Mixed updating in structured populations
David A. Brewster, Yichen Huang, Michael Mitzenmacher +1
Evolutionary graph theory (EGT) studies the effect of population structure on evolutionary dynamics. The vertices of the graph represent the individuals. The edges denote inter…
The Mixed Birth-death/death-Birth Moran Process
David A. Brewster, Yichen Huang, Michael Mitzenmacher +1
We study evolutionary dynamics on graphs in which each step consists of one birth and one death, also known as the Moran processes. There are two types of individuals: residents wi…
Speciesism in AI: Evaluating Discrimination Against Animals in Large Language Models
Monika Jotautaitė, Lucius Caviola, David A. Brewster +1
As large language models (LLMs) become more widely deployed, it is crucial to examine their ethical tendencies. Building on research on fairness and discrimination in AI, we invest…
Maintaining diversity in structured populations
David A. Brewster, Jakub Svoboda, Dylan Roscow +3
We examine population structures for their ability to maintain diversity in neutral evolution. We use the general framework of evolutionary graph theory and consider birth-death (b…
