Replacers and their evolutionary stability in the Moran process on graphs
Michal Pecho, Jakub Svoboda, Lenka Kopfová +2
Evolutionary dynamics in finite structured populations are commonly modeled by the Moran Birth-death process. A key quantity is the fixation probability of a single invader attempt…
Approximating the Uniform Value in Hidden Stochastic Games with Doeblin Condition
Krishnendu Chatterjee, David Lurie, Raimundo Saona +1
We study \emph{zero-sum two-player hidden stochastic games}, where players receive partial observations of the state. We focus on a central solution concept for analyzing long-dura…
Genotype specificity and spatial arrangement govern the direction and magnitude of selection in variable environments
Hossein Nemati, Kamran Kaveh, Jakub Svoboda +2
Spatial environmental variation can either amplify or suppress the fixation of beneficial mutants in structured populations, yet the interplay of ecological factors and spatial str…
Predicting success of cooperators across arbitrary heterogeneous environmental landscapes
Amir Kargaran, Kamran Kaveh, Krishnendu Chatterjee
Cooperation is central to the organization of complex biological and social systems. Most theoretical models assume homogeneous environments; in reality, populations inhabit spatia…
Uniform Value and Decidability in Ergodic Blind Stochastic Games
Krishnendu Chatterjee, David Lurie, Raimundo Saona +1
We study a class of two-player zero-sum stochastic games known as \textit{blind stochastic games}, where players neither observe the state nor receive any information about it duri…
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…
