网络流是图论中的一种理论和方法，研究网络上的一类最优化问题。就是将问题

It is a network flow theory and methods of graph theory, a class of optimization problems on the network. The problem is, in a way analogous to solve the water problem. Network flow theory was originally founded by Ford and Fulker in 1956, including the theory and algorithms of two parts. The key network flow is the introduction of the concept of "flow" in the network. There are a large number of networks, such as power grids, water supply network, transportation network, communications networks, etc. in our daily lives. In these networks, the "flow" are ubiquitous. When in recent years to solve problems related to networks, the network flow plays an important role. <br>We can use a simple example look at the issue of network flows. <br>Suppose you have a simple network traffic, the network has only one

Network flow is a theory and method in graph theory, which studies a kind of optimization problem on the network. is a way to compare a problem to a water flow problem. The theory of network flow was originally founded by Ford and Fulker in 1956 and consists of two parts: theory and algorithm. The key to network flow is to introduce the concept of "flow" into the network. In our daily life, there are a large number of networks, such as power grids, water pipe networks, transportation networks, communication networks and so on. In these networks, "flow" is common. Network flow has played an important role in solving network-related problems in recent years.<br>We can use a simple example to look at the problem of network flow.<br>Suppose there is a simple transportation network, which has only one

Network flow is a theory and method in graph theory. It studies a kind of optimization problem on network. It is a method to solve the problem by analogy with the flow problem.
