## Abstract

Dinic has shown that the classic maximum flow problem on a graph of n vertices and m edges can be reduced to a sequence of at most n - 1 so-called 'blocking flow' problems on acyclic graphs. For dense graphs, the best time bound known for the blocking flow problems is O(n^{2}). Karzanov devised the first O(n^{2})-time blocking flow algorithm, which unfortunately is rather complicated. Later Malhotra, Kumar and Maheshwari devise another O(n^{2})-time algorithm, which is conceptually very simple but has some other drawbacks. In this paper we propose a simplification of Karzanov's algorithm that is easier to implement than Malhotra, Kumar and Maheshwari's method.
