Computational efficiency

Definition

Computational efficiency refers to the ability of an algorithm or computational process to utilize resources such as time and memory effectively to produce results. This concept is crucial in optimizing algorithms, especially in scenarios where large amounts of data or complex calculations are involved. Improving computational efficiency can lead to faster execution times and reduced resource consumption, which is particularly important in algorithms inspired by biological processes.
