Definition: When the execution time of a computation, m(n), is no more than a polynomial function of the problem size, n. More formally m(n) = O(nk) where k is a constant.
Specialization (... is a kind of me.)
sublinear time algorithm.
See also NP, exponential, logarithmic.
Note: Broadly speaking, polynomial time algorithms are reasonable to compute. The time to run exponential algorithms grows too fast to expect to be able to compute exact solutions in all cases.
