Formal definition of big o notation
WebCHAPTER13. BIG-O 164 13.4 The formal definition Let’s write out the formal definition. Suppose that f and g are functions whose domain and co-domain are subsets of the real numbers. Then f(x) is O(g(x)) (read “big-O of g) if and only if There are positive real numbers c and k such that 0 ≤ f(x) ≤ cg(x) for every x≥ k. WebNov 9, 2024 · Big-O For a given function , is defined as: there exist positive constants and such that for all . So is a set of functions that are, after , smaller than or equal to . The function’s behavior before is unimportant since big-O notation (also little-o notation) analyzes the function for huge numbers.

"Big" means "capital", and "O" means order, as in "order of complexity". So named because of the convention of writing "order of complexity" as O (f (x)), e.g., with a capital letter 'O', or a 'Big O'.
