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". 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?

WebThe fastest strongly polynomial time algorithm is due to King et al. [21]. Its running time is O(nmlog m=(nlogn) n). When m= (n 1+ ) for any positive constant , the running time is O(nm). When m = O(nlogn), the running time is O(nmlogn). The fastest weakly polynomial time algorithm is due to Goldberg and Rao [16].
