Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [1] Edmund Landau, [2] and others, collectively called Bachmann–Landau notation or asymptotic notation.
The order in probability notation is used in probability theory and statistical theory in direct parallel to the big O notation that is standard in mathematics.Where the big O notation deals with the convergence of sequences or sets of ordinary numbers, the order in probability notation deals with convergence of sets of random variables, where convergence is in the sense of convergence in ...

The elementary functions are constructed by composing arithmetic operations, the exponential function (), the natural logarithm (), trigonometric functions (,), and their inverses. The complexity of an elementary function is equivalent to that of its inverse, since all elementary functions are analytic and hence invertible by means of Newton's ...
Therefore, the time complexity is commonly expressed using big O notation, typically (), (), (), (), etc., where n is the size in units of bits needed to represent the input. Algorithmic complexities are classified according to the type of function appearing in the big O notation.

In formal mathematics, rates of convergence and orders of convergence are often described comparatively using asymptotic notation commonly called "big O notation," which can be used to encompass both of the prior conventions; this is an application of asymptotic analysis.
Therefore, the complexity is generally expressed by using big O notation. For example, the usual algorithm for integer multiplication has a complexity of O ( n 2 ) , {\displaystyle O(n^{2}),} this means that there is a constant c u {\displaystyle c_{u}} such that the multiplication of two integers of at most n digits may be done in a time less ...
