WebApr 9, 2024 · Again, the fact that we call these solutions "polynomial-time" algorithms is a bit sloppy, but it seems to capture the difference in difficulty between convex minimization and general nonlinear programming in a legible way. Convex programs that are "truly" in P. Finally, Are there any truly polynomial-time algorithms for convex minimization? WebA majority vast majority of algorithms, useful algorithms have small exponents. So, this means that it really makes things in favor of saying that polynomial time algorithms are somehow delineating the boundary between what is fast and what is not fast. Okay, so, having said this, there is a different class of algorithm. So polynomial time.

"An algorithm is said to be of polynomial time if its running time is upper bounded by a polynomial expression in the size of the input for the algorithm, that is, T(n) = O(n ) for some positive constant k. Problems for which a deterministic polynomial-time algorithm exists belong to the complexity class P, 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". " - Polynomial-time algorithms
