When to use Big-Omega Ω notation?
Big-Omega Ω notation is the least used notation for the analysis of algorithms because it can make a correct but imprecise statement over the performance of an algorithm.
Suppose a person takes 100 minutes to complete a task, then using Ω notation it can be stated that the person takes more than 10 minutes to do the task, this statement is correct but not precise as it doesn’t mention the upper bound of the time taken. Similarly, using Ω notation we can say that the best-case running time for the binary search is Ω(1), which is true because we know that binary search would at least take constant time to execute but not very precise as in most of the cases binary search takes log(n) operations to complete.

In the analysis of algorithms, asymptotic notations are used to evaluate the performance of an algorithm, in its best cases and worst cases. This article will discuss Big-Omega Notation represented by a Greek letter (Ω).
