The worst case complexity function is a good measure to use when
A) the load on the system is heaviest
B) we want a guarantee on the performance of an algorithm
C) the best case complexity would lead to incorrect results
D) we want to create an efficient algorithm

Question

Quizplus · Accepted Answer

The worst case complexity function guarantees that an algorithm will not perform worse than a certain threshold, which is important when we want to ensure that an algorithm will always perform within a certain time or resource limit. It may not be the only measure for creating an efficient algorithm, but it is a crucial measure when we want to ensure that an algorithm will always perform in a predictable and reliable manner. Choices A and C are not relevant to the use of worst case complexity function, and choice D suggests that worst case complexity is the only measure of efficiency, which is not necessarily true.
