The Replicator Equation on Graphs
(Elsevier, 2006)
We study evolutionary games on graphs. Each player is represented
by a vertex of the graph. The edges denote who meets whom. A player can use any one of n strategies. Players obtain a payoff from interaction with all their ...
Synergy and Discounting of Cooperation in Social Dilemmas
(Elsevier, 2006)
The emergence and maintenance of cooperation by natural selection is an enduring conundrum in evolutionary biology, which has been studied using a variety of game theoretical models inspired by different biological situations. ...
Dynamics of prebiotic RNA reproduction illuminated by chemical game theory
(Proceedings of the National Academy of Sciences, 2016)
Many origins-of-life scenarios depict a situation in which there are common and potentially scarce resources needed by molecules that compete for survival and reproduction. The dynamics of RNA assembly in a complex mixture ...
Cooperate without looking: Why we care what people think and not just what they do
(Proceedings of the National Academy of Sciences, 2015)
Evolutionary game theory typically focuses on actions but ignores motives. Here, we introduce a model that takes into account the motive behind the action. A crucial question is why do we trust people more who cooperate ...
The organization and control of an evolving interdependent population
(The Royal Society, 2015)
Starting with Darwin, biologists have asked how populations evolve from a low fitness state that is evolutionarily stable to a high fitness state that is not. Specifically of interest is the emergence of cooperation and ...
