Adaptation mechanisms

Definition

Adaptation mechanisms are processes or strategies employed by organisms or systems to adjust and thrive in changing environments. In evolutionary robotics, these mechanisms involve the ability of robotic agents to modify their behavior or structure based on feedback from their interactions with the environment, which is crucial for optimizing performance and achieving specific objectives.
