Big-O Notation

The symbol , pronounced "big-O of ," is one of the Landau symbolsand is used to symbolically express the asymptotic behavior of a given function.
In particular, if is an integer variable which tends to infinity and is a continuous variable tending to some limit, if and are positive functions, and if and are arbitrary functions, then it is said that provided that for some constant and all values and .
Note that Big-O notation is the inverse of Big-Omega notation, i.e., that


Additionally, Big-O notation is related to Little-O notation in that is stronger than and implies .
