Adaptive Operators

Definition

Adaptive operators are mechanisms used in evolutionary robotics that modify the behavior of robotic systems based on environmental feedback. These operators enable robots to adjust their actions and responses in real-time, allowing for more efficient problem-solving and enhanced adaptability to changing conditions. This adaptability is crucial for improving performance and achieving desired outcomes in dynamic and unpredictable environments.
