Question

what is omega notation?

Answer 1

Omega Notation, Ω The notationΩ(n) is the formal way to express the lower bound of an algorithm's running time. It measures the best case time complexity or the best amount of time an algorithm can possibly take to complete.

Answer 2

.The notation {\displaystyle \Omega ({\text{ }})\,\!} has at least three meanings in mathematics:

{\displaystyle f\in \Omega (g)\,\!}means that the function {\displaystyle f\,\!}dominates {\displaystyle g\,\!}in some limit, see Big O notation. In this context {\displaystyle \Omega } is referred to as a lower bound.{\displaystyle \Omega (n)\,\!}is the total number of prime factorsof {\displaystyle n\,\!}counting prime factors with multiplicity{\displaystyle \Omega (x)\,\!} may refer to the Omega function, the inverse of {\displaystyle y=x\cdot e^{x}\,\!} also known as the Lambert W function denoted {\displaystyle W(x)\,\!.{\displaystyle \omega (x) related to the Lambert W Function, is called the Wright Omega Function
