Computational efficiency

Definition

Computational efficiency refers to the effectiveness of an algorithm or process in terms of the resources it consumes, particularly time and space. It is crucial in determining how quickly and effectively tasks are performed, which is especially important in systems that rely on image processing and navigation algorithms. High computational efficiency means that an algorithm can process data faster and use fewer resources, leading to quicker responses and improved performance in real-world applications.

5 Must Know Facts For Your Next Test
