WebDinic algorithm. The Dinic or Dinitz algorithm is based on two notions: a graph level, and a blocking flow (level graph & blocking flow). To determine the level graph, we place the source at level 1, its successors … WebThis is known as Dinic's Blocking Flow Algorithm. The time complexity of the algorithm is O(EV 2) where E and V are the number of edges and vertices respectively. This Algorithm was furthur optimized by using Dynamic Trees, which led to the reduction of the time complexity to O(VElogV). 4.
