The definition of theta also requires that f (n) must be non-negative for values of n greater than n 0 . In simple language, Big Theta () notation specifies asymptotic bounds (both upper and lower) for a function f (n) and provides the average time complexity of an algorithm. As a result, the n 2 term limits the growth of f (n). This is a good answer, but Big-O and Big- have little to do with worst and best cases. However, usually we are interested in a "succinct", "canonical" or "simple" expression $g(n)$, for example of the form $c^n n^a (\log n)^b$, for some $c \geq 1$. I recently saw this. What is meant with finding real and integer constants in Big Oh notation? Web Web Web Big O is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called BachmannLandau notation or asymptotic notation.The letter O was chosen by It conveys the rate of growth or decline of a function.
