Formally, an algorithm is polynomial if there exists a k ∈$$\mathbb{N}$$ such that its running time is in O(n k ), where n is the size of the input. Here, O(n k ) denotes the class of all functions that, for large values of n, grow no faster than c · n k for some constant number c (this is the “Big-O notation”). For instance, when k = 1, the running time is linear, and when k = 2, the running time is quadratic in n.
