Definition

Computational efficiency refers to the effectiveness with which computational resources are utilized to achieve a given task, often measured by the speed and accuracy of algorithms. High computational efficiency minimizes resource consumption, such as time and memory, while maximizing performance, which is essential when solving complex problems in engineering and design. This concept is particularly relevant when developing surrogate models or implementing inverse design methods, where the goal is to optimize processes while managing computational costs.
