Computational efficiency

Definition

Computational efficiency refers to the effectiveness of an algorithm in terms of the resources it uses, including time and space. This concept is essential in ensuring that computational processes, especially those related to algorithmic approaches like genetic programming and robotic simulations, run optimally and utilize minimal resources. Higher computational efficiency often leads to faster processing times and lower energy consumption, which are critical for tasks like evolving robotic behaviors or simulating environments accurately.
