algorithm - Polynomial time and exponential time - Stack Overflow
2019年3月22日 · O (n^2) is polynomial time. The polynomial is f (n) = n^2. On the other hand, O (2^n) is exponential time, where the exponential function implied is f (n) = 2^n. The difference …
Polynomial Time - an overview | ScienceDirect Topics
Polynomial time is a measure of the efficiency of an algorithm, where the running time of the algorithm is proportional to a polynomial function of the input size. (William Gasarch, 2014) It is …
