WebDinic's algorithm or Dinitz's algorithm is a strongly polynomial algorithm for computing the maximum flow in a flow network, conceived in 1970 by Israeli (formerly Soviet) computer scientist Yefim (Chaim) A. Dinitz. The algorithm runs in () time and is similar to the Edmonds–Karp algorithm, which runs in () time, in that it uses shortest augmenting paths.
