The coalescent in finite populations with arbitrary, fixed structure

no code implementations6 Jul 2022 Benjamin Allen, Alex McAvoy

Our formalism allows for arbitrary -- but fixed -- spatial, age, sex, and class structure, with haploid or diploid genetics and any fixed mating pattern.

Selfish optimization and collective learning in populations

no code implementations15 Nov 2021 Alex McAvoy, Yoichiro Mori, Joshua B. Plotkin

When success is measured as payoff in a game played against another learner, mutual selfishness typically fails to produce the optimal outcome for a pair of individuals.

Evolutionary instability of selfish learning in repeated games

1 code implementation13 May 2021 Alex McAvoy, Julian Kates-Harbeck, Krishnendu Chatterjee, Christian Hilbe

However, when two such "selfish" learners interact with each other, the outcome can be detrimental to both, especially when there are conflicts of interest.

Evaluating the structure-coefficient theorem of evolutionary game theory

1 code implementation27 Oct 2020 Alex McAvoy, John Wakeley

In order to accommodate the empirical fact that population structures are rarely simple, modern studies of evolutionary dynamics allow for complicated and highly-heterogeneous spatial structures.

Fixation probabilities in evolutionary dynamics under weak selection

no code implementations10 Aug 2019 Alex McAvoy, Benjamin Allen

In evolutionary dynamics, a key measure of a mutant trait's success is the probability that it takes over the population given some initial mutant-appearance distribution.

Asymmetric evolutionary games with environmental feedback

no code implementations4 Jul 2018 Christoph Hauert, Camille Saade, Alex McAvoy

Interestingly, in non-varying heterogeneous environments, the long-term dynamics are the same as for symmetric interactions in an average, homogeneous environment.
