Selfish optimization and collective learning in populations

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

A selfish learner seeks to maximize its own success, disregarding others.

Evolutionary instability of selfish learning in repeated games

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

We find that selfish learning is insufficient to explain human behavior when there is a trade-off between payoff maximization and fairness.

Fairness

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.
