 | | Big O notation (with a capital letter O -- originally an omicron -- not a zero), also called Landau's symbol, is a symbolism used in complexity theory, computer science, and mathematics to describe the asymptotic behavior of functions. |
 | | Obviously, this notation is abusing the equality symbol, since it violates the transitivity axiom of equality: "things equal to the same thing are equal to each other", as well as symmetry: the notation O(g(x)) = f(x) looks pretty strange. |
 | | Under this convention, it is said, e.g., that f(x) belongs to class (or set) O(g(x)) and the corresponding set membership notation is used. |
