WebAlready Khachiyan's ellipsoid method was a polynomial-time algorithm; however, it was too slow to be of practical interest. The class of primal-dual path-following interior-point methods is considered the most successful. Mehrotra's predictor–corrector algorithm provides the basis for most implementations of this class of methods.

WebJan 1, 1991 · The referenced maximal flow algorithms, when using the Dinic algorithm, have achieved an overall computational worst case complexity of O (n3) for the maximum value flow problem in dense networks with m .^.s n2. This worst case complexity of O (n3), is still the best that has been achieved for dense networks. Yefim Dinitz invented this algorithm in response to a pre-class exercise in Adelson-Velsky's algorithms class. At the time he was not aware of the basic facts regarding the Ford–Fulkerson algorithm. Dinitz mentions inventing his algorithm in January 1969, which was published in 1970 in the journal Doklady Akademii Nauk SSSR. In 1974, Shimon Even and (his then Ph.D. student) Alon …
