- In computer science, polynomial time refers to the running time of an algorithm, that is, the number of computation steps a computer or an abstract machine requires to evaluate the algorithm. An algorithm is said to be polynomial time if its running time is upper bounded by a polynomial in the size of the input for the algorithm.
- Problems for which a polynomial time algorithm exists belong to the complexity class PTIME, which is central in the field of computational complexity theory.
- Cobham's thesis states that polynomial time is a synonym for "tractable", "feasible", "efficient", or "fast".
