Making the most of potential: potential games and genotypic convergence

Area of Science:

• Evolutionary biology
• Population genetics
• Game theory

Background:

• Understanding population genetic convergence is crucial for evolutionary studies.
• Previous models often simplified reproductive strategies and environmental dynamics.

Purpose of the Study:

• To investigate genotypic convergence in asexual and sexual populations under fixed fitness.
• To develop a unified theoretical framework for population convergence.
• To introduce and analyze 'virtual convergence' in varying environments.

Main Methods:

• Mathematical modeling of population genetics.
• Application of potential game theory and multiplicative weights updating algorithm.
• Analysis using the Baum-Eagon Theorem.
• Introduction of the 'virtual convergence' concept.

Main Results:

• Asexual and haploid sexual populations achieve monomorphic convergence.
• Diploid sexual reproduction leads to polymorphic convergence.
• A unified theory links these convergences to game theory and algorithms.
• Virtual convergence ensures optimal fitness growth rates in changing environments for various reproductive modes.

Conclusions:

• Population convergence dynamics can be unified under a game-theoretic framework.
• Virtual convergence offers a robust model for adaptation in fluctuating environments.
• The findings provide insights into evolutionary trajectories across different reproductive systems.
