Description
Priyanka Mehra and Arend Hintze study how populations balance staying robust against staying able to change in this 2024 evolution paper. Their model world has two fitness peaks split by a valley, so populations must dip before they can climb higher. They vary mutation rates and valley depth, plus the ways genes interact.
At low mutation rates, few pioneers crossed the valley. Higher rates brought more crossings, yet lasting majorities on the high peak formed best at middle rates. Pioneers were often replaced later by hardier types. The gene interactions, where one gene affects many traits or modifies others, helped populations trade change against stability. The lessons may guide genetic algorithm design.
