How to Determine Big-Omega Ω Notation?
In simple language, Big-Omega Ω notation specifies the asymptotic lower bound for a function f(n). It bounds the growth of the function from below as the input grows infinitely large.
Steps to Determine Big-Omega Ω Notation:
1. Break the program into smaller segments:
- Break the algorithm into smaller segments such that each segment has a certain runtime complexity.
2. Find the complexity of each segment:
- Find the number of operations performed for each segment(in terms of the input size) assuming the given input is such that the program takes the least amount of time.
3. Add the complexity of all segments:
- Add up all the operations and simplify it, let’s say it is f(n).
4. Remove all the constants:
- Remove all the constants and choose the term having the least order or any other function which is always less than f(n) when n tends to infinity.
- Let’s say the least order function is g(n) then, Big-Omega (Ω) of f(n) is Ω(g(n)).
